Virtual DMIS

USER GUIDE CONVENTIONS Virtual DMIS is designed to run on a number of different computers and operating systems. While many of these platforms are very similar, the look and feel from one system to the next varies enough that it is not possible to write a guide that matches exactly what the user will experience. In an effort to present a consistent documentation that is easy to read with information that can be applied to a number of platforms the conventions described below are used. There are four basic areas: TYPOGRAPHICAL This is the look and feel of this guide. KEYBOARD

A description of key sequences.

VIRTUAL DMIS

How this guide describes the Virtual DMIS Graphical User Interface.

MOUSE

How some of the many types of mice interact with Virtual DMIS

TYPOGRAPHICAL CONVENTIONS Menu Selection Text seen in Virtual DMIS menu selections, or titles have been placed in bold characters for its first occurrence. DMIS Syntax DMIS syntax is typed using uppercase lettering. When examples of code are to be presented, the font will change to a Times New Roman 10 point font. -

THIS IS AN EXAMPLE OF TIMES NEW ROMAN 10 POINT UPPERCASE THAT IS USED FOR DMIS CODE. KEYBOARD CONVENTIONS Keyboards come in many shapes and sizes; each one has its own unique layout and labeling. In addition to confusing, labeling the function of a key can change from one application to the next. Users are urged to take a few minutes and review the notes below to learn the function of keys and key combinations in the Virtual DMIS environment. 1) The keys on your keyboard may not be labeled exactly as they are in the manual. 2) The keys on your keyboard may not be in the same location described in this manual. 3)

Beware of the keys in the numerical keypad area. Keys on the numerical keypad are not the same as keys in the main keyboard area. On some keyboards the ENTER key in the numerical keypad area sends a different code to the computer than the ENTER key in the main keyboard area. This also applies to the dual functions keys like 8 and 4. Well-informed and perceptive users never assume that keys on the numerical keypad will always function as advertised.

2

Introduction

Key-names Keyboards have keys and each key has a name, a "key-name". There is a key on the right it is larger than the other keys. On many keyboards, the word "enter" is printed on top of this key. In this guide, key-names are shown in capital letters. For example: 1) The Control key is shown as CTRL in this guide. 2)

The Escape key is shown as ESC in this guide.

3) The Enter key is shown as ENTER in this guide 4)

The Alternate key is shown as ALT in this guide

Single Keys Each key on a keyboard has a function and this function varies from one application to the next. The specific functions of keys in the Virtual DMIS application are listed below. ENTER ENTER and RETURN, are two common names for this key. Regardless of the name, these keys perform the same action in Virtual DMIS. In the documentation, 'Press ENTER' means that either ENTER or RETURN may be pressed, unless specifically instructed otherwise. TAB The TAB key will move the cursor from field to field within a window. Numeric Keypad Keys On most computer systems, the keyboard is extended to include a numeric keypad on the right-hand side. These keys may be used for numeric input. The NUM LOCK key must be activated. Usually there is a light on the keyboard, indicating when NUM LOCK has been activated ARROW KEYS (a4,0.=:>) The arrow keys are used to manipulate the graphics on the screen. To see more information to the right of the machine, press the right arrow, etc. All four directions are available (left, right, up, down). HOME, END, PAGE UP, PAGE DOWN These keys may be used to move the cursor through the database area of your screen. These may be used once a program has been created

Virtual DMIS

Hot Keys

Keys can be used in combination as shortcut keys. This is commonly used in Virtual DMIS. For example: 1. ALT+P means to hold down the ALT key and while still holding down the ALT key pressing the P key. 2. ALT+SHIFT+C means to hold down the ALT and SHIFT keys and while still holding down the ALT and SHIFT keys pressing the C key Keys can be used in sequence as shortcut keys. 1. ALT P means to press and release each of these keys in order; press the ALT key and release (often a menu bar is then highlighted) then press the P key. 2. ALT F C means to press and release each of these keys in order; press the ALT key and release (often a menu bar is highlighted at this juncture), then press the F key and release, then press the C key. Accelerator Keys

Functions on a menu in some applications have a key-name in that function underlined. These functions can be accessed with a single keystroke when the menu is active. Virtual DMIS supports accelerator keys for all the pull down menus on the Systems Utilities Menus. The key-name that points to the accelerator are always the keys are always the first letter or number in the name and are not underlined in Virtual DMIS. NOTE: When more than one item in the pull down begins with the same letter, pressing the accelerator key a second time will bring the user to the next selection with the same beginning letter. For example, the hot key ALT P will open the project menu and then pressing the accelerator, will bring the user to the Import CAD selection; pressing the key, a second time will bring the user to Import Sensor Data. This holds true for all pull down menus. Labels

When labels of features, sensors, tolerances, etc. are referred to in this document, the default system labels and names are assumed. Menu Selections

When prompted to select from a Virtual DMIS menu, the text of the menu selection will be typed in bold lettering. If there is an associated icon, the icon may be included in the text as well.

The left button (referred to as LMB in this manual) is the primary button. Most selections in the software are made using the LMB. Selections are made using a single 'click'. Functions may also be performed by pressing and holding a mouse button. The movement of the mouse while a button is activated will determine the amount of change on the screen.

RMB

The right mouse button (referred to as RMB in this manual) will present a variety of menus depending on where the pointer was resting when the right button was activated.

POINT Means to position the mouse pointer until the tip of the pointer rests on whatever you wish to point to on the screen. CLICK Means to press and then immediately release the mouse button without moving the mouse. DOUBLE CLICK Means to quickly click two times. This is used to activate an application. For example, 'Double click' on the Virtual DMIS logo to enter the software. The speed of the double click may be set by right clicking on 'My computer' on your desktop. Select open. Open the control panel on the menu and select mouse. The slider bar on the button tab will allow you to increase or decrease the speed of the 'Double click'. There is a test area next to the slider where you may test your speed. DRAG 'Drag' means to point and then hold down the mouse button as you move the mouse DRAG AND DROP means to point; hold the mouse button down over an item; slide the mouse across the screen and release the mouse button when the item is over the desired location. BOX

'Box' is created by holding the LMB and dragging the pointer on the screen diagonally. This function is used in the best-fit feature construction. This feature is also used to zoom in on an area of the Graphics area of the screen.

Installing Virtual DMIS

INSTALLING VIRTUAL DMIS Note: Virtual DMIS is installed at the factory when a CMM is shipped. If a retrofit kit was purchased, the software will be installed on the new computer that was supplied with the kit. Installation of the software should not be required. Virtual DMIS software is protected by a License key. There are two types on license keys; one requires a parallel port and the other uses a USB port. Each License key has it's own unique serial number and a license number associated with it. Each license number is generated by the Virtual DMIS central facility. As EACH SERIAL NUMBER IS MATCHED TO A SINGLE LICENSE KEY, it is vital that in situations where there are multiple copies of Virtual DMIS, each License key remains with the system for which it was intended. After installation ensure you have the following files backed up on a disk: C:\winhome l\vms.ini

This file contains the password required for installation of the software and all of the tunable parameters (size, feeds and speeds, etc.) for your machine. C:\vmshome2thin\errormap.txt This file contains the error correction data from the laser calibration. The file name generally matches the serial number of your CMM. For complete documentation, refer to the Virtual DMIS installation guide. 3

Home

HOMING THE CMM If this screen is displayed the CMM is ready to home.

Home Icon

Homing the system means to move to a preset location. This location is often referred to as the machine zero. Sending a machine to its home position allows the controller to read in the error map for the Dimensional Measuring Equipment. The error map is a mathematical adjustment correcting any structural geometry issues electronically. The error map is a fine tune adjustment of the system. DCC MACHINES ONLY •

Press the servo button on the controller if you have a DCC machine.

MANUAL MACHINES ONLY •

For a Manual Machine position the machine physically in the proper Home location before LMB on the home icon

HOMING THE CMM FOR ALL MACHINES •

Select the HOME icon and single click with the LMB. The HOME icon is the little house on the right at the top of the screen. OR

•

Select Tools from the system menu along the top of the screen;

•

Select Machine Status from the pull down menu;

•

Select Machine from the pop-up window;

•

Select Go Home Icon from the menu on the screen. For more information on this procedure, go to Page 57 of this guide.

Once a CMM has been sent to the home position, the Graphics view of the CMM should coincide with the physical machine. If the Virtual DMIS software has been installed as a retrofit the graphics may not be an exact match. If the hardware for the controller is in the computer used on the CMM, sending the CMM to home is only required when the computer has been shut down and restarted. For systems with external controllers, the system is sent home when the controller has been powered off or if the controller has been reloaded. Once Virtual DMIS is opened, the homing icon will automatically appear. It is not necessary to home the CMM if the emergency stop button has been engaged.

INTERACTIVE LOGO & DRIVER STATUS ICON The upper right hand corner of the screen displays several informational icons that define machine and controller status. The conditions and required actions associated with each Icon are described below.

HOME: This Icon indicates the machine needs to be "Homed". (See Glossary)

VIRTUAL DMIS LOGO: When the system is ready for operation, the 3V DMIS logo is seen with a ball cycling along the "V" and the Driver Status Icon is green. When a program is executing or when an error occurs this Icon is replaced with one of the following Icons.

DRIVER STATUS ICON:

The driver status icon is a round light that may be present in one of five conditions. 1. The driver status is Flashing and GREEN when, the CMM is on-line with Virtual DMIS. 2.

The driver status is GREEN and not flashing when the system is performing a task that requires time, for example computing the profile of a curve or surface.

3. The Driver Status Icon is not displayed for OFF-LINE Virtual DMIS installations. 4.

The driver status is GREEN / RED when, Virtual DMIS is in Simulation Mode. Simulation mode will disengage the motors of he CMM and part programs may be run in an offline mode without logging out of the online software. Program simulation allows the user to run the program and watch the probe path on the screen.

5. The driver status is RED when some aspect of the CMM is functioning correctly.

PROGRAM EXECUTION: During program execution, when a feature is being measured, this icon replaces the Virtual DMIS logo.

SERVO'S OFF: When the servos are off, this icon will appear; the button switch shown in the icon will appear green.

EMERGENCY STOP: When the emergency stop button is activated, this icon will appear. The Driver status light will change from its normal state, green, to red. In addition, if the E-Stop is depressed, the button will change to red.

LOW AIR PRESSURE: When this Icon is displayed, the machine must not be moved! Determine why there is insufficient air available to the machine, remedy the problem and the low air Icon will be replaced by the Virtual DMIS logo. 23

Virtual DMIS

OUTSIDE OF ERROR MAP ON X-AXIS: Probe position is outside of the X error map range. This could affect the results of the measurement. This icon can appear if the user attempts to measure features without first sending the CMM to the home position.

OUTSIDE OF ERROR MAP ON Y-AXIS: Probe position is outside of the Y error map range. This could affect the results of the measurement. This icon can appear if the user attempts to measure features without first sending the CMM to the home position.

OUTSIDE OF ERROR MAP IN Z AXIS Probe position is outside of the Z error map range. This could affect the results of the measurement. This icon can appear if the user attempts to measure features without first sending the CMM to the home position.

MISSING ERROR COMPENSATION FILE: This indicates that there is no error compensation available on the system or that the error compensation file location and the VMS.INI file entry for the error compensation file do not match.

SCALE ERROR: This indicates that there is scale read error. This may also appear if the ON Motion Servo motors are not ready. This is used on systems with analogue reader heads. If it appears it indicates a scale read error on the reader head as well as the machine.

TCPIP This logo indicates a TCPIP connection is active. Typically, this appears while working on a dual arm CMM.

CAD files are accessible from local directories, CD ROMs, or across network drives. When selecting the import CAD option a file management window appear.

NOTE: Any file that is imported into the Virtual DMIS UI must reside on the local computer. Translated files may not be imported from the network or from CD. Although the file formats IGES, STEP, VRML, IV, DXF and VDA are supported, they must be translated first using one of the available Virtual DMIS translators. In the file management window the default type is RLE. RLE files contain precision data of the imported geometry. An RLE file will not be displayed without the associated WRL file. WRL files by themselves can be displayed however the WRL by itself may not be as precise as the .RLE file. With "learn on' the full pathname to the CAD model is saved in the DMIS program.

Virtual DMIS CAD Translation Virtual DMIS supports several neutral file formats; IGES, STEP, and VDA. These files are translated into two files, a WRL (VRML) file used for display and an RLE file used to store mathematical data. VRML and IV files do not require translation. If an IGES file is translated, the file name remains the same and an extension is added to the end of the file name once the translation is complete. Example - SAMPLE.IGS will be converted to SAMPLE.IGS.WRL and. SAMPLE.IGS.RLE. While a file is translating, it is possible to continue working within Virtual DMIS. The translator may be run in the background. The CAD Translator Shortcut is automatically placed on the desktop when Virtual DMIS is installed. If the short cuts are not on the desktop. The *.exe files required are found in the C:\vmshome\Vmlges directory. T

Wire Mode

This mode affects both face and wire translation. There are 5 modes for IGES and 2 for STEP files. This can reorder the wire frame to correct missing surfaces or gaps between patches.

30

System Utilities Menu

Visual Tolerance

This setting only affects the .WRL file by changing the number of triangles for each face. The larger the Visual tolerance setting, the fewer triangles involved in the graphical view, resulting in a smaller WRL file. If the translated file is too large or difficult to manipulate in Virtual DMIS, the visual tolerance value may be increased and the file translated a second time. A lower visual tolerance may fill gaps in surface data that appear at a higher Visual Tolerance value.

Entity Filtering

Select the entities to include or exclude by checking the appropriate boxes.

Mirror Plane

Sets the plane to mirror about if a mirrored part is desired

Virtual DMIS requires the CAD files are stored on the local computer for translation. Translation of files stored on a network drive may be slow and the translated files may be corrupted. A log file will record the options selected for the translation. The log file name is the combined with CAD file name. For example, the log file for IMS Block Surface.igs will be "IMS Block Surfaceigs.translator_options.log". The file will be created in the folder containing the CAD file. IMPORT SENSOR DATA Imports previously defined sensors from existing projects. If sensors were calibrated in the existing project, they will be available under the actual sensor list. If the sensors were not calibrated, they will appear only under the nominal sensor list. It is important to note that sensors brought into a project in this manner do not get included in the definition of the sensors in the DMIS program. The code will be written to change to the various sensors and as long as the sensors are in the sensor database, the program will run. However, If the DMIS program is to be transported to a different CMM, or the programmer plans on using the Virtual DMIS Simplified User Interface (SUI 4), it is important that the code to import the sensor database is written to the part program. 5 Caution: If any sensor data is defined prior to importing sensor data, it will be overwritten without warning. IMPORT COORDINATE SYSTEM Imports previously defined coordinate systems from existing projects. If any labels are duplicated, the existing coordinate system will be renamed. Files are renamed as follows: coordinate system being imported has the label PCS1 and that label is present, the existing label is renamed to PCS1_2. Coordinate systems may be recalled into a DMIS program in the same manner as sensors.

The program would call up this tolerance file using the 'IMPORT TOLERANCE DATA' command. Once tolerance data has been imported, the User will not be required to type in any tolerance information. To apply a tolerance drag and drop tolerance information from the tolerance database into any open tolerance window. When importing tolerance data containing DIAM and CORTOL data, the current settings will be overwritten and the imported values will become the default. If the imported tolerance data does not contain these two tolerance types, the current default values remain active. Here is an example of recalling data from a stored project Recalled sensor data, named coordinate systems or tolerance labels are stored by project name. Because the data is stored by project name, the recall screens appear identical, however only the requested data will be input.

IMPORT FEATURES This will import previously saved project features. An example of application would be to set up a fixture in one project and measure a part in a second. If the user required a tolerance between a fixture feature and a part feature, it would be necessary to import the feature data from the fixture project.

IMPORT DMIS This allows the importation of programs created previously in either Virtual DMIS off-line or Virtual DMIS on-line. The previously defined DMIS programs are then resident in the program database area for use. The program may be modified, or executed from the database area. This option also may be used to import programs created using other vendor software. The vendor of the proprietary software must supply the DMIS posting processor: This enables users to create programs on alternate systems and run the program utilizing Virtual DMIS.

Video last frame pause - Allows the user to determine how long the help video will remain on the screen once it has completed running. A setting of '1000' will keep the picture for one second, where a setting of 10,000 will keep the picture for ten seconds. This setting is stored in the VMS.INI 6 file. Whisker Magnification - Graphics display will display form error whiskers for a measured feature when it is dragged and dropped on the graphic area. Form errors will not be displayed for constructed or nominal features. The size of the whisker is a reflection of the error and the whisker magnification. This value is read at start up from the VMS.ini file and is stored to the file when Virtual DMIS is exited properly. The sizes of the whiskers are a combination of the view arrangement and the actual form error on the feature. While displaying form error graphically, the user may zoom in on the feature so that it is the only item on the screen. If that is the case, the whiskers may have a smaller value in the setup as opposed to the size required for the complete view of the part. Remember while displaying form graphically that the error on a feature will change from one part to the next. The whisker magnification may need constant adjustment.

The sphere-bounding vector is also used to define the orientation of the mounting stem for the calibration artifact. Stem may be referred to as Stalk by some users If the stem of the calibration artifact is not orthogonal to the CMM surface this vector must be updated to provide the capability of automatic sphere measurement.

Note: These settings will affect the probe path available if Automatic Sphere measure is to be used during a part program For systems using the Renishaw TM UCC controllers, the sphere-bounding vector is defined in the VMS.ini file under the [RENISHAW] section of the file. The vector stored in the VMS.INI file is required by the UCC controller for use of the analogue scanning heads. The sensor calibration routine for the scanning heads is a function of the controller, NOT Virtual DMIS. Sphere bounding vector This defines how the MGAGE (calibration artifact) has been mounted on the CMM table. If a standard artifact is being used, the vector will be 0.00, 0.00, -1.00. Specifically the vector defines a plane that intersects the calibration sphere at the equator with the vector of the plane aimed into the mounting stem. Sphere bounding ratio This value is used to avoid collisions with the stem of the qualification artifact. The value defines what percentage of the sphere is available above the bounding plane to the automatic calibration routine (in this case above means in the direction of the plane vector). In order to clear the mounting stem while calibrating a star tip or a sensor with an angle of inclination greater than ninety degrees, the system is installed using a sphere bounding ratio of 67%. A larger the mounting stem requires a larger value entered into the window. In the diagram on the following page, the Bounding ratio removes approximately 33% of the sphere surface that is available to the probe. The image above indicates a sphere-bounding ratio of 63% (100%-37%). If the stem were larger, the value entered into the window would be smaller.

Enable Smart Measure This activates the Smart Measure algorithms. When enabled, the user is not required to select the feature type about to be measured. The Smart measure algorithm will determine the feature types as they are being measured. This tool is a time saver when programming on-line on a large machine, the amount of keyboard interaction being greatly reduced. To measure with Smart Measure simply go and measure the feature. The open measure window will display the counters in RED rather than in Yellow. The counter will go up in numbers as hits are added to the feature, not counting down as in the normal measurement mode. When one point is taken, the window will read and label a Point. As hits are added, the window will update the feature type accordingly. If two hits are taken in directions that cannot possibly solve a line, a buzzer will sound indicating those 2 points do not solve a feature. This occurs when measuring a circle. The feature measure window will display 2 points in the buffer until the 3 ro hit is taken. At this point, the feature measure window will change to Circle. To complete measurement of one feature and move to the next press the enter key on the teach pendant or click on the calculate feature now, a green check on the measurement window. If, while measuring the feature displayed is not the anticipated feature type the user can switch the feature by selecting the proper feature from the Feature tool bar. For example: •

This menu bar allows users to create new features from existing features through geometric applications. Examples of various constructions are found on page 157 of this document. Features used for construction may be actual or nominal features. Actual features are features that have been defined and then measured or constructed. Nominal features are features that have been defined and not yet measured. Some constructions can create different elements. For Example: "Tangential to 2 circles". When more than one resultant feature is possible, all possibilities can be viewed by selecting the down arrow in the Calculated Feature Window. To view the solutions in the graphics area LMB on the drop down list and select each feature in the Calculated Feature, window. The feature displayed in that window will appear as a green temporary feature in the graphics area. When the next feature is selected and the current is not applied, the temporary feature will disappear. The characteristics of the calculated feature are listed on the right side of the construction window. Direction of a linear feature may be reversed by selecting the REVERSE VECTOR key (green key) to the right of the calculated feature field.

After one of the available solutions is selected, the constructed feature is removed from the list of possible solutions and the construction window remains open. This prevents duplication of constructed features. Once all possible results have been constructed, the construction window will automatically close. This does not mean that if there is more than one solution every option must be calculated. Once the required feature has been constructed, select the APPLY button in the lower righthand corner of the window. To exit the construction window, select the 'X' in the upper right corner of the construction window or make a new menu selection. If the fields in the construction window contain features that do not solve the selected construction, the Calculated feature type window and the feature label field will remain empty. If a calculation is requested that is not arithmetically sound, the APPLY icon is unavailable to the user. When a feature construction window has two features available for input, the feature identified as `featl' is the last measured feature and leat2' is the second last feature measured. These features are automatically placed into these fields. Constructed features do not automatically update into these fields. If features other than the last two are required for the construction, features from the database may be dragged into the input fields, typed in or using Object select the User may click on the required features.

In all of the tolerance windows, an icon toggles between a feature control frame and calculator is displayed at the bottom of the window. By default, Virtual DMIS opens all tolerance windows with the option to calculate a tolerance on specified features. By clicking on the 'calculate tolerance' icon, the function of the window is changed to tolerance definition. z•-• 03M

2E1

Tolerance definitions may be used to predefine a list of general tolerances to be used in the program. While calculating tolerances will define a tolerance and calculate a tolerance when the APPLY button is selected. While inputting tolerance values, it is not necessary to input the leading zeros. Example: Tolerance + 0.10, may be input as .1 or 0.1 While placing the tolerance values in the input fields, it is necessary to place a minus `-' sign in front of the negative tolerance value if the tolerance has a negative value. The sign is not assumed by Virtual DMIS. Using Predefined Tolerances

Once a tolerance has been defined, the user may drag and drop the definition from the tolerance database into the Label field of any tolerance window. This will cause the tolerance window to display the appropriate selection from the tolerance menu. By using this method, the User is not required to re-enter similar tolerance data while programming. As with the constructions, if a calculation is requested that is not mathematically sound, the APPLY button is unavailable. All tolerances are calculated using the ANSI Y-14.5M standard for Geometrical Dimensioning and Tolerancing. For more information on Tolerance application, please refer to page 173 of this document. Note: In the VMS.INI file is as setting that will link a size tolerance to a feature. TOFEATLINK=1 If this setting is switched on, every tolerance will have a unique label. It will not be possible to apply DIA1 to more than one circle. This is true even if the size tolerance for several diameters is constant. This tool bar may be customized using the smart editor.

SENSORS

Sensors (or probes) are tools that are used to collect information from the part being inspected. Depending on the type of sensor, they need to be defined and calibrated. This tool bar manages the sensors. Definition, calibration, selection and deletion of sensors can be performed here. The windows that are activated on selection of one of these menu options allow the user to drag and drop previously defined or calibrated sensors into the input fields. When working with sensors the user must 1) Verify the graphics representation of the probe assembly using the following tool System Tool Bar Configuration Sensor Configuration Create a graphics model of the Sensor Assembly Or

2)

Perform Sensor Length and mount from the tool bar displayed above. This will have the user measure the qualification artifact two times. Once the routine is completed, Virtual DMIS will have an accurate mathematical model of the sensor assembly. The Sensor Length and mount routine is also useful if the stylus is customized for a specific jog (shaft bent). When this routine is executed, the new length and direction of the probe head is stored in the VMS.INI file. If using Standard Renishaw parts for the probe configuration, and the position of the probe head has been certified with the sensor length and mount during an earlier session of Virtual DMIS, the routine is NOT necessary. If the sensor auto calibration routine fails by missing the calibration artifact, it may be due to incorrect values in the senor length and mount. If this is the case, run the application.

Once Virtual DMIS has the correct data for the sensor length, programming may be performed without the need of first generating a sensor list and calibrating a sensor list. Virtual DMIS will have a reasonably accurate location for any sensor position allowing the user to program and generate the required list of sensors prior to calibration. Once a program has been completed, the sensor list may be easily a quickly calibrated. Calibration may be performed one sensor position at a time using tools on the Sensor Tool Bar, or by suing the pop up menu in the Nominal Sensor Database. The sensor functions are linked to several areas of the user interface. For a more detailed description, please refer to Using Virtual DMIS in this guide or in the Virtual DMIS On Line help, For the Beginner. This tool bar may be customized using the smart editor. For a more detailed description of sensor applications, please refer to the Sensor section in Using Virtual DMIS page 175

COORDINATE SYSTEMS

Once a part has been placed on the CMM table a Part Coordinate System (PCS) must be created from datum features. The tools for creating the datum reference frame are available on this tool bar. This tool bar allows the user to create and manage the coordinate systems. Virtual DMIS has additional tools for complex coordinate systems in the software keys on this tool bar. Virtual DMIS provides the tools required to generate Right Hand Coordinate Systems. Right Hand Rule It states that the direction of one axis combined with the direction of a second axis determines the direction of the third axis. The three axes are mutually perpendicular to one another. When working with a 3D coordinate system in Virtual DMIS, the major axis is identified as the first axis in the work plane and the minor axis is the second listed axis calculated 90 degrees CCW to the major axis. The projection axis is not listed. Work plane XY Work plane YZ Work plane ZX When building a coordinate system, each feature used as a datum of the coordinate system will set everything it can without undoing any of the previous steps. To understand what is happening with the coordinate system, hold out your 'Right' hand. With the palm of your hand facing up, curl in the small finger and the one next to it. The three remaining fingers represent the relationship of the axes in the coordinate system. Stand at the front of the CMM, look down the Y+ axis, you may notice your thumb is pointing along the machine X+ axis. Your index finger is pointing along the machine Y+ axis, and your middle finger is pointing along the machine Z+ axis. There are several methods to performing this relationship. You may find an easier method for determining the axial relationships. This tool bar may be customized using the smart editor. For further information on the Coordinate System Tool Bar, refer to the Using Virtual DMIS Section, paqe 181.

PROGRAM

The Program tool bar supplies the tools to direct the execution and development of part programs. This tool bar supplies the tools for running part programs, opening and saving DMIS programs, stopping the system at specific intervals and opens a DMIS editor. This tool bar may be customized using the smart editor. The last icon on the tool bar has several functions: 1. While running a program, hitting the "Stop Light" will cause the controller to stop immediately. 2. If there is output sitting in the print buffer, hitting the "Stop Light" will force the printer to send any data in the buffer directly to the printer. 3. If variable have been declared, hitting the "Stop Light" will reset the variables database. There will be no declared variables after this button is selected. To reactivate the variables, the user must step through the declaration portion of the part program. NOTE: Alt+C will perform the same task as the "Stop Immediately" button.

The procedure on the Smart Tool Bar runs a certification program that may also be used by the service technician while calibrating the CMM. Further instructions are supplied with the purchase of the MCG MY TOOL BAR My Tool Bar allows the user to place previously defined macros into the software. This is also useful if the user is running only a few parts. Customizing this tool bar allows the user to create a uniquely personal system. This tool bar also enables the user to read previously defined macros and DMIS files into an existing project. Macro files are given the extension ".mco" and DMIS files are given the extension ".dms". The files are not evaluated while they are read into the project; hence, the extensions are simply a useful user identifier. In a single user environment, the files are stored in "VMSHOME\Users\Macro and VMSHOME\Users\Program". For a multi-user environment, the path is "VMSHOME\UsersVogname\Macro and VMSHOME\UsersVogname\Program". This tool bar must be customized using the smart editor, and is empty at installation. HELP

This button activates the on-line help function of Virtual DMIS. On-line help is an electronic User Guide. Users are encouraged to investigate this tool. Help appears on top of the Virtual DMIS Graphics area; to return to inspection simply select the Minimize button and help will drop to the Windows Tool Bar.

SMART TOOL BAR The smart tool bar is one of the most unique and powerful features of Virtual DMIS. The tool bar itself is displayed below the Main Tool bar and changes dynamically with each different selection from the main bar. Not only does the smart tool bar update itself with each selection from the main tool bar, it also changes dynamically with each geometric feature measured. The Smart Tool Bar has two functions. 1. The primary function of the Smart Tool Bar is to view the functions typically applicable to the last two measured features. This area has been described as a metrology calculator. The user may set specific tasks linked to combinations of features. To customize Virtual DMIS, use the Smart Editor selection under Tools. This has been described under the Tools drop down menu selection located on the System Utilities Menu. The options that are presented with each selection from the main tool bar are standard choices and set as default in Virtual DMIS. These default selections however can easily be changed and modified, by either the user or a system administrator. This allows the software to be customized for each installation requirements if desired. To modify the Smart Tool bar, select the Smart Editor under Menu>Tools>Smart Editor option. NOTE: The last two measured features may also be used to lock the projection feature of subsequently measured features. Please refer to "LAST TWO FEATURES" in the "DATABASE AREA". 2.

The secondary function of the Smart Tool Bar is to display all of the menu options associated with items on the Main Tool Bar. The first image below shows the contents of the smart tool bar, with the system having just measured a circle and a plane, as indicated by the two left hand icons. To the right of the two features is a selection of the most commonly used options that could be required of a circle and/or a plane. otw,

Last Measured Features This area displays the last generated features. Measured or constructed. Virtual DMIS defaults to show the last 5 features with the last item at the bottom of the list and the 5 th last at the top of the list. This is referred to as the legacy order. The order in which the items appear may be changed by a user in the VMS.INI file. 10 Feature Titles The feature icon is blue, (bold) only if there are features in that category measured. This way you can see at a glance, which feature lists have been minimized and which are empty. Renaming a feature is done by slicking on a feature name to highlight and once it is highlighted, select the feature name again. Once the new label is entered, move the mouse off the highlight. This will cause the find and replace utility to open automatically. In the open utility, select replace all and the label name change will be applied to the ACTUAL feature database, the NOMINAL feature database and to all occurrences of the label in the DMIS part program. For more information on the Find and Replace Utility, refer to page 101 in this document. RMB on the feature title will bring up a pop up menu. This menu is constant for both the Actual and the Nominal database.

VARIABLES DATABASE I Intgr Variables are data-types that MUST be declared. The Variables IT1(19) database is used for High Level Language Programmers. It provides database utilities to the programmer. Variables may be declared for It Real RL1 (70.87871 use in calculations such as volume or area, or creation of Headers, where the operator must input serial numbers or Shift or Lot C Char information. CH1[70.87871 As with all other titles in the database area, a double click on the primary title will collapse or expand the list.

Intgr The data type integer is a signed whole number such as 1 or —1. It is a value to be used in calculations. For example, loops in programs will use whole numbers only.

Real is any number requiring precision greater than an integer, it may be a whole number. For example, a circle diameter may result in a whole number.

Char Allows for the substitution of alphanumeric data to be passed as text. An example charvar=text Character variables may be alphanumeric 1, 2, 3, 4 A, B, C, D, RMB on one of the Intgr, Real or Char categories brings up the pop-up menu.

Once the Variable has been defined, the label cannot be altered. Variable name checking against DMIS major and minor words is only performed when DMIS is at 4.0 or higher level. Value sets the numerical value for the Variable Obtain, when available, allows the user to drag either Actual or Nominal features into the input field.

Index provides a list of available parameters to assign to the Declared Variable. DMIS DECL is a drop down list with two options. It is only available when Learn ON. This controls where the Variable Declaration appears in the part program. Last Decl will send the definition of the current variable to the line in the part program where the last declaration was defined. Current Line will place the defined variable where the pointer is currently at in the DMIS program. 93

User Interface

In the DMIS code, the directory structure in the variables database will grow accordingly, sorting variables according to type. The variables database will display the variable data as it is generated in the part program. Once a variable has been declared, it may not be declared a second time. This becomes evident when debugging a part program or re-running a program without reaching the ;41 ENDFIL command. The variables database is cleared when the STOP IMMEDIATELY icon is selected on the Program tool bar. If an error message appears while executing a program, providing the option to select Cancel or OK to continue, the variables database is not cleared. The DMIS language provides a range of Declaration techniques. If using the DMIS standard while programming, the following variable declarations are available. DECL/LOCAL DECL/COMMON DECL/GLOBAL DECL/LOCAL will provide a variable that is declared within a macro. Once the ENDMAC line is executed, the variables are removed from the database. DECL/COMMON generates a variable that is constant throughout the current session of Virtual DMIS. These variables are not removed at the endfil line nor when the Stop immediately icon is selected. Common variables do not invoke an error message if the declaration statement is executed while the variable resides in the database. This variable type is only removed from the database area by exiting Virtual DMIS. DECL/GLOBAL is the variable type used by Virtual DMIS. If Global does not appear in the declaration line, Virtual DMIS assumes GLOBAL. Global variables are available to the part program and are cleared on ENDFIL or the stop immediately icon.

Last 2 measured features

The Last 2 Measured Features performs three functions. They are: 1. Controlling which functions appear on the Smart tool bar 2. Locking vectors to a feature. 3. Auto Project Controlling the Smart tool bar As features are measured, the Smart tool bar is automatically updated. It presents the most common functions applicable to the last 2 MEASURED features. Users may also drag and drop features from the database area into the last 2 measured features fields. This causes the Smart tool bar to update with respect to the selected features. Locking Vectors to a feature Double click on a feature residing in the last 2 measured feature icon area will Lock the l ei featur.Thiconwldspaytemgonhlf.Oceaturisokd,hevcI of the locked feature becomes the vector of any subsequently measured 2D features. Although all feature types can have the lock applied to them individually, the application is only a valid Metrology application for the following feature types: Plane Cylinder Cone 3d Constructed line It is recommended that as soon as the user has finished using the Locked feature that the feature has the lock removed Auto Project RMB on a Locked feature reveals a pop up menu (displayed in image below) Auto Project Onto Locked Feature(PL1)

vo Auto Project Onto Locked Feature

A right mouse click on the feature will re-display the menu so the user may confirm the sate (on or off). Move the mouse off the menu and LMB to exit. Once enabled the Icon changes ELJ indicating any features measured will be measured with the vector of the locked feature and a second feature will be created at the locked feature. For example, if a circle was measured 1 mm below a locked plane, CR1 would be generated with the measure and then CR1_P would automatically be calculated at the plane. This second feature will be a true 3D feature; meaning that the feature will be repeatable along all three axes, regardless of manual or automatic point collection It is recommended that as soon as the user has finished using the Locked feature that the feature has the lock removed If both features in this area are locked, the last measured feature takes precedence. If the features were dragged onto the fields and both were locked, the left field takes precedence.

Selecting any feature Icon from the Feature Measurement Tool Bar will display the Feature Measurement Window shown in the graphics area, above. There are twelve informational and control areas in the Feature Measurement Window, beginning with the Feature Label and ending with Relative Measurement. Feature Label

If previously defined feature is not used the label increments sequentially based on the nomenclature existing in Virtual DMIS, for example CR1 then CR2 for circle or CIRCLE1 then CIRCLE2 if the nomenclature has been redefined by the user in Change Feature Id, located under Tools in the System Utilities Menu. The user may also re-type any desired syntactically valid label desired. For example DATUM A_ in place of PL1. A previously defined label may be dragged from the Database Area and the feature measured, manually or if properly defined in automatic mode, on DCC CMM's.

103

User Interface

Point Counter In normal measurement based on the number of desired points, this counter will decrement until all the points are taken. Please refer to additional notes under Finish Measurement later in this section. Smart Measure mode the point counter will increment and the numbers in the counter will be displayed in Red. Finish Measurement Allows the user to end a feature measurement regardless of the number of points required in the point buffer. Once the minimum number of points has been reached, the finish measurement icon becomes active. Auto Measure Is active when the feature being measured has been previously defined and the label is dragged from the 'database area into the label area of the Feature Measurement Window. Circles, points, lines, spheres and Cylinders may be measured in auto mode. Point Counter Slider Bar The number of points to be collected during the feature measurement is increased or decreased using the slider bar. The altered number will remain in the measurement window for all subsequent features of the same type, until the number of points is changed again. The maximum number of points to be measured on a geometrical item is nine hundred ninety-nine. Curves and Surface scans do not have this limit. Performance dramatically degrades above five hundred points on all except the most powerful computers. Once the minimum number of hits has been recorded, the feature will be calculated and the form will begin calculation as well. If the output window is open during measurement, the output will update with each point taken beyond the minimum set requirement.

Scan Is supported for lines circles, cylinders, arcs, curves and surfaces. A previously defined circle may be scanned after taking two points while a surface requires five points to define the direction and boundary. 13 Delete Selected Point This feature allows the user to look at the form error introduced by each point within an uncompleted feature, select obvious errors and delete the points. Once the feature has been completed, this item is not available. The selected point appears in red in the histogram. Unless a point is selected by the user, the last point is highlighted for, review and delete options Point Buffer Increments as points are taken. The user may select any point in the buffer with the LMB, and delete it using Delete Selected Point. Deviation Informational only, shows maximum deviation and error (deviation) of last measured point. Histogram Gives an overall view of the form of the feature being measured. Clicking on a bar within the histogram selects the actual point within the feature. This allows the user to view the form introduced by the selected point.

13 For more information on feature scan and surface scan, refer to the scanning document on the Virtual DMIS CD.

104

Feature Tool Bar

Obtain Control Window The active CAD model (Geom) label may be dragged from the database area into this window; planes, cylinders and spheres are also supported. When a model or geometry is in this window, the vectors for the measured feature are obtained from the model or geometry. Measured features are nominally defined at the surface of the selected entity.

Projection This is an animated icon provided to indicate the application of the Obtain Control Window. Relative Measure is supported for feature point, circle, arc and slot. Selecting the down

arrow on a supported feature will display the following window. There are three supported formats: Vector Build

Vector build obtains a vector from a locally measured plane and uses this vector to measure the defined feature. Two variables are required. "Ni" is the number of points to be measured in the local plane. "Dist" defines how far away from the edge of the nominal feature the local plane will be measured. All points in the local plane are evenly distributed around the nominal feature.

Drag the label of a nominal or actual feature from the database and the vector of the feature will be used in the measurement of the defined feature.

Fixed Axis

When selected the vector is locked to a single axis relative to the active part coordinate system.

MODE There re 3 modes of programming available with this first key. Manual Manual mode creates a part program requiring operator interface. Features within the progran, will be measured by the User either with the joystick or by manipulating the probe by hand. The measurement technique is dependant on the type of CMM. This mode of programming is used on manual machines where there are no servos to drive the machine and semi-automatic machines where the joystick supplies the only power of movement. The method of programming may also require the use of manual mode. For instance, the program may require manual set up of the coordinate system or of a temporary coordinate system.

Auto Auto mode is the easiest form of programming. This method uses the probe settings,clearance planes automatic collision avoidance" (if activated) to determine clearance moves and probe position. Auto mode also makes use of the systems ability for circular interpolation 15 . Caution: All lines of programming between the feature MEAS and ENDMEAS command are ignore by the program (i.e. PTMEAS, GOTO and sensor change commands). If there are specifi moves or contact points that are required within the measurement of a feature, Auto Mode i not the program mode to use. While running a feature in Auto mode, Virtual DMIS can ch ck for the first GOTO move in the measurement block and check for inconsistent use of the s nsor. This function is activated using the following menu selections: •

Configuration

•

System Settings

•

While measuring a feature using Auto mode, the sensor approach and retract values are checked against machine travel. If the sensors approach and retract values exceed machine travel, a warning message is displayed.

Go to System Tool Bar, Configuration, System Settings and the Sys Status Tab for more information on Collision Avoidance. 15

Go to section of machines settings for more information on Circular interpolation. 107

User Interface

Prog Program mode is easiest described as copycat mode. When running a program that was created in program mode, the probe will move exactly where programmed. The GOTO points are read and executed within features (between the feature MEAS and ENDMEAS commands in the DMIS code).

PROBE COMP Probe compensation has two settings, On and Off. This toggle switch displays the current setting. There are very few occasions to turn the probe compensation Off. One example would be for scanning. While measuring points on an unknown surface the User may choose to turn probe compensation off. When these points are read into a CAD station, they may be adjusted by probe radius to negate the possibility of probe compensation errors. Probe compensation status does not effect the calibration.

WKPLANE Work plane determines the aOtive plane for the measurement and evaluation of twodimensional features. The work plane may be changed at any time during a program as required by the inspection. While setting up the initial coordinate system, the work plane may not be changed until the orientation (direction of the axes) has been determined. XY Two-dimensional features will be viewed along the Z-axis. YZ Two-dimensional features will be viewed along the X-axis. ZX Two-dimensional features will be viewed along the Y-axis.

LENGTH This selection determines the unit of measurement currently in use in the program. MM CM IN FT M

Millimeter Centimeter Inch Feet Meter

F

The unit of measurement may be switched at any time during the programming sequence. In some facilities, it may be ne ssary to report the results of an inspection in both inches and millimeters. This dual reporti g may be programmed into the part program. The change of units will be reflected in thevalues after changing the units. It is not necessary to re-measure a feature to report in more than one unit.

108

Program Status Tool Bar

ANGLE There are two systems available for measuring angles. This selection, similar to the length selection, determines the unit of angular measurement for the program. As with length, the unit of angular measurement may be switched at any time during the programming sequence. If while programming angles between features are to be reported as Degree : Minutes: Seconds There i a switch In the angle between tolerance window. If the switch is not turned on, refer to the MS.ini section of the online help file.

ANGDEC Sets the angular unit to decimal units. Each one-degree is divided into one hundred units.

ANG RAD Sets the angular units to Radians. In many theoretical applications, the angle is measured as part of a circle. Radians are defined as The length of the arc subtending the angle An angle so defined is expressed in circular measure, having the radian as a unit. The circumference of a circle is pi times its diameter, 2 pi radians equal 360 degrees.

User Interface

COORDINATE The coordinate setting sets t e type of coordinate to be reported by the Digital Read Out (DRO). This also determines he setting for output purposes. Two types of coordinate reporting are available.

CART — This sets the display to the Cartesian coordinate system. The Cartesian coordinate system consists of three axes perpendicular to each other. Virtual DMIS uses the right hand rule in coordinate system definition. The axes are referred to as X, Y and Z. The work planes are defined using two of the t ree axes, for example the XY work plane. These axes are oriented with the positive Y- a is running 90 degrees counter clockwise to the positive X-axis. The Z-axis is 90 degrees cou ter clockwise to the X-axis and the Y-axis. POL — This sets the display t Polar coordinates. Virtual DMIS analyzes two-dimensional polar coordinates. The axes isplayed are R (radial distance), A (angular location) and H (height). Radial distance is a alculation of distance along the longitudinal axis and the transverse axis of the feature Polar location is simply a different means with which to report the location of a feature. For example, if a feature was located at X30.00 mm Y50.00 mm the polar location could be c lculated using the Pythagorean theorem and trigonometry R = square root (Deviation of X squared + Deviation of Y squared) = 58.31 Where deviation is distance from the origin. While the Angular location may be calculated using trigonometry A = ARC TAN (delta y/delta x) = 59.03 degrees Rather than calculate these values out when required, simply change the coordinate readings from Cartesian to polar. This tool is helpful when working with bolt hole patterns. It is important to note that th features are stored in the feature database as either Polar or Cartesian entities. If the locat on of a Cartesian entity requires Polar output, the programmer must perform the Tolerance f nction of Coordinate located on the tolerance tool bar. Nominal values may be edited in the • utput window as either Polar or Cartesian coordinates, but once save in the output window is elected, the feature is stored with the coordinate type. Any output from the output windo will reflect the coordinate setting that was present when the Save button was selected. LEARN Learn toggles between on an• off.

Learn ON — When learn mod is on, a project is created. The project will store DMIS program, sensors, coordinate systems, features (nominal and actual), raw data output files and tolerance data.

Learn OFF — This allows the .ystem to be utilized as an inspection station. Virtual DMIS allows the system to measur and evaluate features but the methods used for these functions are not stored. Ste •s taken while learn mode is turned off are not repeatable without a User HINT: if while running a proven program, one feature will not measure automatically because the part is out of spec; ensure learn mode is OFF, change to manual mode, run the line of code to measure the offendin feature, return PROG setting to either AUTO or PROG (as the program originally set) and ntinue running from current line. 110

Show Feature Graphical Processor

The feature Graphical Processor (FGP) application designed to allow users to analyze measured data by removing unreasonable point data from a feature. Unreasonable flyers may be caused by dirt on the feature, or a bad hit with a probe, vibration in the lab. Whatever the cause, the FGP is available to the user to remove flyers.

^.VirtualDMIS Feature Graphical Processor

Once the FGP is opened, the feature in question may be dragged from the database into the new window. The FGP allows the user to: 1)

Edit the current feature

2) Generate a new feature with flyers removed 3) Graphically display nominal and actual feature 4) Show points within the feature and the properties of each point 5) Magnification of form error to show points 6) Display form of feature as a form distribution chart 7) Zoom in on the isolated feature The F P supports the following features: •
