Mastercam X4 Maintenance Update 1 Mastercam X4 Maintenance Update 1 (MU1) includes the following enhancements and improvements.

General System Enhancements Mastercam Customer Feedback Program Mastercam X4 MU1 includes an optional data feedback tool called the Mastercam Customer Feedback Program. Participation is completely voluntary. If you choose to turn this functionality on, it runs during every Mastercam session, automatically collecting and sending usage information to CNC Software, Inc. (CNC). This data is used only for quality and product improvement purposes and helps give CNC an idea of the relative value of various functionality within its products. The data does not include any user model data or any information that could be used to re-create models. This program cannot/will not collect any data for the purpose of reverse engineering.

6 • WHAT’S NEW IN MASTERCAM X4 MU3

IMPORTANT: The Mastercam Customer Feedback Program will at no time collect any data that is not relative to Mastercam. No sensitive, personal, or otherwise private data will be gathered. The feedback tool is turned off by default, and you must choose to participate in the program by clicking the option shown below in the Mastercam Customer Feedback Program dialog box, which appears when you first open Mastercam after an install. You can also open this dialog box at any time by choosing Help, Customer Feedback Program from the Mastercam menu bar. After choosing the Yes option, click the OK button to begin participating.

If you choose to participate, some of the types of data that this tool collects include:

 The Mastercam build number  Your SIM number  The name of the function you called and how you accessed it (toolbar button, hot keys, menu) The combined data gathered from Mastercam Customer Feedback Program participants is used by CNC Software to answer the following types of questions:

    

What Mastercam functions are used the most, and which are used the least? How often and when is Mastercam Help used? Which file translators are used, and how often? Which C-Hooks are used and how often? What commands are used sequentially or in conjunction with each other?

MASTERCAM X4 MAINTENANCE UPDATES • 7

Note: The lists above are not comprehensive. These are examples of the types of data CNC Software will collect.

If you are running the Mastercam Customer Feedback Program, an icon

displays

in your Windows program tray in the bottom right corner of your computer screen. Notes: • Participating in this program will not impact your processing time or computer performance. • If you are running the Mastercam Customer Feedback Program, the tool will automatically close when you close Mastercam. • The data gathered by this program is sent to CNC when you shut down Mastercam, or after a specific number of transactions. • If you do not have an Internet connection, the data will be saved to your local drive. The next time you open Mastercam, the program will attempt to send the data. If the data cannot be sent over a period of five days, it is automatically purged from your system. • You can change your participation at any time, and any number of times during a Mastercam session. For example, you can let the program collect data up until a certain point in your work, turn it off for a period of time, and then turn it back on.

Stock Shading and Stock Boundary Toolbar Buttons Mastercam X4 MU1 allows for quicker toggling of stock shading and stock display with two new features. These buttons are located in the Shading toolbar.

 Stock Display

- This button switches stock display on and off. It

maintains the stock shading's last state when it is switched back on.

 Stock Shading

- This button switches stock shading on and off.

Notes: • Stock shading will not shade the stock unless the stock is on. (If shading is on and the stock display switch is used, shading will be turned off.) • In Lathe, these icons control both spindles at the same time and affect the display of the chuck jaws, steady rest, and tailstock.

8 • WHAT’S NEW IN MASTERCAM X4 MU3

Unselect All in Chaining A new Unselect All button on the Chaining dialog box lets you unselect all chains with a single click. This makes unselecting chains much easier when you have a large number of chains.

MASTERCAM X4 MAINTENANCE UPDATES • 9

Wireframe Feature Recognition for Mirrored Shapes A new option in the Chain Feature dialog box controls whether Feature Recognition selects or ignores mirrored chains. You can access this dialog box by clicking the Chain Feature Options button on the Chaining dialog box.

10 • WHAT’S NEW IN MASTERCAM X4 MU3

Wireframe Feature Parameters in System Configuration These additional options on the Chain Feature page add the ability to set up defaults for wireframe feature recognition in chaining. You can access the System Configuration dialog box by choosing Settings, Configuration from the Mastercam menu bar.

Immediate Mode Commands in the MRU Toolbar A new option on the Screen page of the System Configuration dialog box determines whether immediate mode commands display in the MRU toolbar.

An immediate mode function is a command that executes without first canceling the current function. Immediate mode functions interrupt a function, and when they have finished, they return to the function. The opposite is a root function, which cancels any existing active function before starting up.

MASTERCAM X4 MAINTENANCE UPDATES • 11

Mill Enhancements Locking Feed Rates and Speeds You can now set Mastercam to not update feeds and speeds once a toolpath has been created. To turn on this option, choose Settings, Configuration from the Mastercam menu bar and go to the Toolpaths page to select the Lock Feedrates option.

When you initially create a toolpath, the feeds and speeds are populated based on the Feed Calculation settings on the Tool Settings tab of the Machine Group Properties dialog box.

12 • WHAT’S NEW IN MASTERCAM X4 MU3

All the fields shown in the following picture remain set from that point forward (manually editing is allowed). Selecting another tool or reselecting the same tool will not cause the fields to change.

If you want to reinitialize the settings, you can right-click in the tool list and select Re-initialize feeds & speeds.

MASTERCAM X4 MAINTENANCE UPDATES • 13

3D Rest Machining - Targeted Previous Operations Mastercam X4 MU1 adds the option to select the set of previous operations upon which a rest machining operation is based. You can choose from previous operations in the current toolpath group, previous operations in the current machine group, or all previous operations in all machine groups. This change affects the following toolpath types:

 3D HST Rest Roughing  3D HST toolpaths that have a Rest Material page (Waterline, Scallop, Raster, Pencil, Radial)

 Surface, Rough, Rest Mill

HST Rest Roughing - Outside In Option This new option on the 3D HST Rest Roughing Cut Parameters page creates offset passes from the outside towards the inside (in a core roughing manner) rather than always using an inside towards the outside (area clearance) cutting method.

14 • WHAT’S NEW IN MASTERCAM X4 MU3

Lathe Enhancements Cutoff/Pickoff/Bar Pull Setup C-Hook You can use this new function to translate geometry and create reference points for the programming of a part transfer operation from the main spindle to the sub spindle and/or a bar pull operation prior to a cutoff toolpath. This new add-on is specifically used for parts cut from bar stock, not parts cut from slugs, castings, or forgings. You can access this function by two methods:

 From the Mastercam menu, choose Settings, Run User Application, and open the file PickoffSetup.dll.

 From the Mastercam menu, choose Settings, Customize and set up a custom toolbar with the Define geometry for stock cutoff, pickoff and pull operations button from the MultiTasking category.

This function makes it possible to:

 Make a copy of the part geometry that is positioned correctly in the subspindle for toolpaths on the backside of the part.

 Make a copy of the part geometry that is positioned as would be after a bar pull operation just prior to a cutoff/pickoff operation sequence

 Create reference points for the bar pull and cutoff toolpaths.  Create a reference point for the Tplane origin for backside operations in the sub-spindle.

MASTERCAM X4 MAINTENANCE UPDATES • 15

IMPORTANT: The left and right stock margins defined in the Component Geometry tab (Cylinder) dialog box are also used by this function.

Cutter Compensation Improvements A variety of cutter compensation issues have been addressed in X4 MU1. These changes should improve the overall performance of cutter compensation. Because it is impossible to imitate all the different ways cutter compensation is used and predict the outcome of each scenario, the new changes are not turned on by default in X4 MU1. Recognizing the need for proceeding with caution, these new fixes can be turned on in the Mastercam Applet. Once we have verified that no unanticipated problems arise from these new changes, they will be on by default in X5. To turn on the updated cutter compensation: 1 Go to the Windows Start Menu and choose All Programs, Mastercam X4, MCAMX Control Panel Applet. 2 Click on the [+] before the Mastercam properties option to expand the list. 3 Select Toolpath support from the Mastercam properties list.

16 • WHAT’S NEW IN MASTERCAM X4 MU3

Click the drop-down list next to Lathe toolpath cutter compensation and select Use improved lathe toolpath cutter comp.

Router Enhancements Onion Skin Operation Updated to Tree-Style Dialog In keeping with the ongoing conversion of toolpath dialogs to promote consistency, the Onion Skin operation type has been converted to the new tree-style dialog format.

MASTERCAM X4 MAINTENANCE UPDATES • 17

You can access this dialog box from the Advanced button on the Additions tab in the Toolpath Nesting dialog box.

Wire Enhancements Additional Tab Stop Option An additional option to stop on a tab at a defined position from the end of the tab has been added for X4 MU1.

18 • WHAT’S NEW IN MASTERCAM X4 MU3

Reset Pass Number Option This new option becomes available when you select either Cancel taper after pass or Apply taper after pass as the Pass settings option on the Taper page.

This switch works similarly to the Reset pass number on tab cuts option on the Cut Parameters page.

Where Reset pass number on tab cuts allows for the selection of the rough cutting conditions on the first pass across the tab, this new option on the Taper parameters page allows for the selection of roughing parameters when changing to/from the taper/ land cut.

MASTERCAM X4 MAINTENANCE UPDATES • 19

New Reset Taper Option for Lead - Entry/Exit This option controls how the Lead Out set on the Leads page is trimmed. In the example below, the Lead Out is set to be trimmed to 2mm.

If Reset Taper is not selected, the path would end at the Max lead out position, leaving the machine in a tapered position. On some machines, this is an undesirable condition; taper must be at 0 (zero) to change the G41/G42 compensation and other settings. With Reset Taper selected, the path continues as needed (in XY or UV) to bring the machine to a vertical position, while still respecting the requested trimmed length of the Lead Out.

Post Enhancements A new pre-defined variable — move_ang_pln$ — indicates the plane in which the move_ang$ value applies. By default, this is set to 0 (zero) for compatibility with older posts. Initialize it to a negative value to have MP dynamically update the value. MP updates it based on the toolpath type:

 Lathe toolpaths switch it to -3.  Non-lathe toolpaths switch to -1.  Nothing currently automatically switches to -2, but this can still be used to initialize automatic processing. Set it to a positive number to manually lock the value to a specific plane.

move_ang_pln$ Values -3 -2 -1 0

1 2 3 4 or greater

XZ plane; automatic processing YZ plane; automatic processing XY plane; automatic processing (Default) XY plane; static value. This value is processed the same as 1. It is provided to maintain compatibility with existing posts. XY plane; static value YZ plane; static value XZ plane; static value Disable all move angle calculations.

General System Enhancements Mastercam X4 introduces several features to improve your productivity, no matter what level of Mastercam you own.

Dynamic Planes Dynamic Planes is a new method for defining construction planes (Cplanes), tool planes (Tplanes), planes, and work coordinate systems (WCS) in Mastercam X4. You can now define the desired plane using an interactive graphical gnomon to establish the plane's origin and orientation. Everything centers on using the gnomon and its position-sensitive functionality. The gnomon is made of an Axis Origin and three axes, each consisting of a First Leg, Axis Label, Second Leg, and Axis Arrowhead. Each piece has its own functionality.

1 Axis Origin - Select to place the origin of the gnomon in 3D space. You can use AutoCursor positions, type in XYZ values, or sketch a point. Generally, this is the first manipulation of the dynamic gnomon. 2 First Leg - Select to move the gnomon along the selected axis. Move the gnomon along the scale displayed in the graphics window. You can also use AutoCursor positions, type in XYZ values, or sketch a point. 3 Axis Label - Select to rotate around a perpendicular axis. Rotate the gnomon along the scale displayed in the graphics window. You can also use AutoCursor positions, type a rotation angle, or sketch a point. Selecting the axis label for rotation follows these rules:

 X axis label = rotate around Y  Y axis label = rotate around X  Z axis label = rotate around X

22 • WHAT’S NEW IN MASTERCAM X4 MU3

4 Second Leg - Select to rotate around a perpendicular axis. Rotate the gnomon along the scale displayed in the graphics window. You can also use AutoCursor positions, type a rotation angle, or sketch a point. Selecting the axis second leg for rotation follows these rules:

 X second leg = rotate around Z  Y second leg = rotate around Z  Z second leg = rotate around Y 5 Axis Arrowhead - Select to align the gnomon to existing geometry. You can also use AutoCursor positions to place the gnomon on an entity. You may align the gnomon to:

 a line or solid edge  tangent to a spline or arc  normal to a surface or solid face TIP: You can modify the behavior of the gnomon with the Gnomon Settings dialog box. Access this dialog box by clicking the Settings button on the ribbon bar or dialog box or by holding the [Ctrl] key and right-clicking anywhere in the graphics window.

Pre-Drilling FBM Drill now includes a simpler way for pre-drilling to only drill the pilot hole diameter and not perform any pre-drilling up to that hole size. The Pre-drill pilot holes only check box on the Pre-drilling page generates only pilot hole pre-drill cycles followed by finish hole drill cycles, such as tapping or reaming.

Create Additional Geometry This new option on the Setup page allows FBM Drill to create additional geometry while creating the drill toolpaths. This geometry can be used to select holes for multiaxis drilling. The Vector of drill engagement option creates a vector from the top

of the hole to the deepest depth of the hole, taking tip compensation and tool selection into account.

FBM Mill Slug Cutting Users who work with wood and composite materials on large vacuum table machines will definitely appreciate this enhancement in how FBM Mill handles through pockets. FBM Mill now detects when a through pocket area is large enough for a vacuum table to hold down the resulting slug. Instead of pocketing the entire area, Mastercam uses a contour operation to cut the outermost passes of the profile, leaving behind a slug that is held in place by the vacuum table. Note: The Slug cutting page is available only when the Through features check box is selected on the Feature detection page.

Mill Level 3 Enhancements Mastercam X4 offers several enhancements for Mill Level 3 and Router Pro users, including support for multi-threaded processing, new filters for improved finish results, and an updated interface for Curve 5-axis and Drill 5-axis toolpaths.

Multi-Threading Support Multi-threading is a special form of program multitasking that allows a single program to execute portions of itself concurrently (as opposed to a single-threaded program, which executes in a linear mode). This processing mode allows Mastercam to split the programs that regenerate its largest, most complex toolpaths into smaller, separate program threads that execute simultaneously. Programs that are multi-threaded can process more quickly and efficiently. In Mastercam X4, multi-threaded toolpath processing is available for all of Mastercam's 3D surface high speed toolpaths (HST), and for the following multiaxis toolpaths:

 Multisurface 5-axis  Flowline 5-axis  Port 5-axis You can enable/disable multi-threaded toolpath processing as part of your Mastercam configuration for all Mastercam sessions (Settings, Configuration, Toolpaths page).

64 • WHAT’S NEW IN MASTERCAM X4 MU3

Or you can use the Toggle Multi-Threading button to turn it on or off for the current Mastercam session.This button is located on the What’s New in X4 toolbar, and in the Settings, Customize dialog box in the Multi-Thread Toolpath Manager category. Once you activate multi-threaded processing, whenever you generate/regenerate 3D HST and multiaxis toolpaths, you can continue working in Mastercam once the toolpaths have been sent to the Multi-Threading Manager (MTM). This dialog box shows you all existing threads, along with their current states, progress bar indicators, and processing status.

You do not have to wait for the toolpath regeneration to complete before starting another Mastercam function. Mastercam continues to process these toolpath files in the background. You can use the Toggle Multi-Threading Manager button to control the display of this dialog box for the current Mastercam session. This button is also located on the What’s New in X4 toolbar, and in the Settings, Customize dialog box in the Multi-Thread Toolpath Manager category. When processing toolpaths in multi-threaded mode, the Toolpath Manager displays two icons to indicate that toolpaths are being processed as threads in the MultiThreading Manager. The icons are green or yellow spools of thread.

 

Green icons indicate threads that are being processed in the MTM. Yellow icons are assigned to dependent toolpath threads (for example, rest toolpaths). Dependent threads require data from prior “parent” toolpath threads. Dependent threads cannot begin processing until the MTM completely finishes processing the parent thread (including translation of the binary NCI data).

MILL LEVEL 3 ENHANCEMENTS • 65

Toolpath Refinement Mastercam X4 adds a new toolpath refinement feature — 3D Advanced Toolpath Refinement — to 3D surface toolpaths. The 3D Advanced Toolpath Refinement helps you optimize cycle times and produce better finishes with your 3D surface toolpaths. This new feature combines the existing arc/line filter with new functionality that supports smoothing, randomizing points, creating minimal points, maintaining a consistent distance between points, and even converting arc motion to all G1 motion.

 Adjusting toolpath results using Toolpath Refinement 1 From the Mastercam menu, choose File, Open. 2 Go to ..\Documentation\ExampleParts and select REFINE.MCX. This part includes four surface high speed toolpaths. 3 In the Toolpath Manager, expand the first toolpath in the list.

4 Click the Parameters icon to display the Surface High Speed Toolpaths dialog box.

66 • WHAT’S NEW IN MASTERCAM X4 MU3

5 Select the Arc Filter/Tolerance page from the tree control. Notice that the Total tolerance value is set to 0.001.

6 Click the Refine toolpath button to open the Refine Toolpath dialog box.

MILL LEVEL 3 ENHANCEMENTS • 67

In the Tolerances Distribution section, Mastercam displays the formula it uses to apply the 0.001 Total Tolerance value. For this toolpath, the percentages of Line/Arc filter tolerance and Smoothing tolerance are set to 0%, making the Cut tolerance 100% of the Total tolerance value. This indicates that the 3D Advanced Toolpath Refinement feature is not in effect. 7 Select the Smoothing Settings check box to activate smoothing for the toolpath. This automatically adjusts the Smoothing tolerance in the Tolerances Distribution to 5% of the Total tolerance and reduces Cut tolerance to 95%.

8 Select the Line/Arc Filtering Settings check box to activate line/arc filtering for the toolpath. Line/arc filtering and smoothing tolerance are applied approximately equally.

68 • WHAT’S NEW IN MASTERCAM X4 MU3

9 Slowly move the + slider, located immediately after the Cut tolerance field, to the right. This adjusts the ratio between the two sections in 5% increments, but respects the final number for the total tolerance.

10 Move the slider in between the line/arc filter and the smoothing tolerance to the left. This adjusts the ratio between the two fields.

Notes: There are other ways to change the distribution between the fields: • Type values directly into the fields • Use the sliders in the My preferences section. 11 Click Cancel to close the Refine Toolpath dialog box. 12 Click Cancel to close the Surface High Speed Toolpath dialog box.

Examining the Toolpath Results 1 Select all four toolpaths in the Toolpath Manager and click the Backplot button. 2 Expand the Backplot dialog box using the arrow button in the upper left corner so you can see all four toolpaths.

MILL LEVEL 3 ENHANCEMENTS • 69

3 Select the first toolpath.

4 Select the Display Endpoints button to see the entity endpoints within the tool motion. 5 Zoom in on a section of the part. The first toolpath has no filter applied, so you can see how the points line up with neighboring points. This introduces the potential for a low-quality surface finish.

70 • WHAT’S NEW IN MASTERCAM X4 MU3

6 Select the second toolpath in the Backplot dialog box. The Refine Toolpath filter is turned on for this toolpath, which randomizes the point placement to avoid patterns.

7 Select the third toolpath in the Backplot dialog box and notice the reduction in the number of points. For this toolpath, the Minimize number of points option in the Smoothing section is selected, which further filters the toolpath and creates smaller NC files. 8 Select the last toolpath in the Backplot dialog box. This toolpath uses the Use Fixed Segment Length option in the Smoothing section. No two points are more than 0.04 inches apart, which is ideal for high speed machining.

9 Click OK to close the Backplot dialog box.

Toolpath Refinement Frequently Asked Questions Mastercam X4’s Toolpath Refinement gives you a single control panel for two powerful methods of toolpath improvement. The first method — Line/Arc Filtering — you may already be familiar with. The second method of toolpath refinement — Smoothing — is new to Mastercam. Note: The Cut Parameters Smoothing option used to round corners in high speed toolpaths is unrelated to 3D Advanced Toolpath Refinement. Here are a few commonly asked questions that should help you decide if the new Smoothing feature is for you:

Which toolpaths use Toolpath Refinement? All 3D surface toolpaths and surface high speed toolpaths have the option of using Toolpath Refinement. This includes both roughing and finishing toolpaths.

What does Toolpath Refinement Smoothing do? Smoothing distributes a toolpath’s node points, avoiding the clustering and grouping of points that can cause marks and other imperfections. It does this through shifting, removing, and/or adding node points along an already generated toolpath.

What are the benefits? Smoothing delivers three clear benefits on certain parts:

 Superior finish quality. Tests show a much smoother, consistent finish with fewer visible tool marks on many parts.

 Reduced machining time. Smoothed toolpaths eliminate many of the small moves common to 3D toolpaths, letting you run the program at much higher feed rates.

 Reduced tool wear.

How do I access the Refine Toolpath options? Choose a 3D surface toolpath or a surface high speed toolpath from the Mastercam Toolpath menu or toolbar. Then choose one of the following actions based on your toolpath selection: For tree-style toolpaths: 1 Choose the Arc Filter/Tolerance page.

72 • WHAT’S NEW IN MASTERCAM X4 MU3

2 Enter a Total Tolerance value. 3 Click the Refine Toolpath button. For tab-style toolpaths: 1 Choose the toolpath's parameters tab (for example, Rough radial parameters or Finish project parameters). 2 Enter a Total Tolerance value. 3 Click the Total Tolerance button. Try out this powerful new technique and see for yourself the smoother, faster results it can deliver. You can also use it together with Mastercam’s standard Line/Arc filtering, as the two techniques work well together.

Minimum Tilt in Multiaxis Toolpaths This new feature automates tool axis motion when the tool or holder encounters a potential collision with a selected surface. These options are available in Port 5-axis, Flow 5-axis, and Multisurface 5-axis toolpaths. You can enter a clearance distance to maintain between the tool shank/holder and the part. For Mastercam X4, this function can only be used with a lollipop cutter.

New Tree-Style Dialogs for Curve 5-axis and Drill 5-axis Mastercam continues to convert toolpaths to the new tree-style dialog boxes. The new dialogs for Drill 5-axis and Curve 5-axis streamline the programming process.

MILL LEVEL 3 ENHANCEMENTS • 73

Circle Mill 5-axis Toolpath The new Circle Mill 5-axis toolpath is useful for creating circular pockets normal to a surface, parallel to a line, or referencing a plane in order to insert an object such as a fastener. It can also generate round holes at any orientation where drilling is not

horizontal and vertical trim check boxes in the Results dialog are used to specify which cuts to make.

Lathe Enhancements Mastercam X4 Lathe provides many new features to make your lathe jobs faster and more efficient, including several enhancements for grooving toolpaths, better functionality for creating turned profiles, and a user-friendly interface for C-axis toolpaths.

Grooving Enhancements Mastercam X4 includes several improvements that provide a new level of control for Lathe grooving toolpaths.

Multiple Chains Grooving Option The new Multiple chains option allows you to select more than one groove for a groove toolpath.

When you use this option to chain multiple grooves, the chaining function is impacted in the following ways:

   

The type of chain in the Chaining dialog box defaults to Partial Chain. You are prompted to select an entry point or chain the inner boundary. Using the Partial Chain method, select the first entity and then the last entity.

Using the Point method, select an entry point or points. You can then select a retraction point or complete the chaining process.

84 • WHAT’S NEW IN MASTERCAM X4 MU3

Because the grooves can be different widths, you can only select the new Middle overlap option on the Groove Finish parameters tab.

LATHE ENHANCEMENTS • 85

Feed and Speed Settings for Finish Passes New parameters in Mastercam X4 Lathe allow you to set speeds and feed rates specifically for finish groove passes, making it easier to produce your desired finish.

Corner Dwell on Finish Grooving The Groove finish parameters page now includes a Corner Dwell option. The dwell occurs at the intersection of the wall or corner geometry and the flat bottom of the groove. Dwell may not work in odd-shaped grooves.

86 • WHAT’S NEW IN MASTERCAM X4 MU3

Independent Feed Rate for First Plunge The Groove rough parameters page has a new option to set a feed rate specifically for the first plunge move, providing precise control of your toolpath motion.

Tool Inspection Mastercam X4 Lathe also provides the ability to program tool inspections into your groove toolpaths. You can program safe approach and retract locations for performing the tool inspection. You can also define specific conditions for when you want to inspect the tool.

LATHE ENHANCEMENTS • 87

IMPORTANT: This feature only works if the post is customized to capture the new information in the NCI file. For more information, see Support for Lathe Tool Inspection on page 94.

Create Turn Profile Customers asked for a better solution to the problem of generating a turned profile from a solid. Mastercam X4 includes a new function for doing this, which replaces the Solid to 2D Profile function in Mastercam X3. The Turn Profile functionality is a subset of the Create, Silhouette Boundary functionality.

You can access this new function by selecting Create, Turn Profile from the Mastercam menu. After you select an existing solid, solid face, or surface, the following dialog box displays.

88 • WHAT’S NEW IN MASTERCAM X4 MU3

Two methods are available for generating the turned profile:

Spin — Designed for complex, non-symmetrical geometry containing Mill and Turn features. The entire model is spun to generate the profile of the maximum turned envelope for the component. This option can also be used on symmetrical geometry. Slice — Designed for symmetrical, revolved geometry and a simple slice is taken through the model. The final profile can be limited to the Upper or Lower profiles or both sides. The new function always uses the current WCS X axis as the axis of rotation and the resulting profile is created in the Top view of the active WCS.

New Tree-Style Dialogs for C-axis Toolpaths Since C-axis toolpaths are very similar to the 2D chain-based and point-based toolpaths, these toolpath dialog boxes are also being converted to the new tree-style dialog. This will help maintain consistency between Mastercam Mill and Mastercam Lathe.

LATHE ENHANCEMENTS • 89

Round Boring Bar Display in Verify Mastercam X4 now shows round boring bars in Verify. The display is a simplified representation of round tools, including boring bars. Collision checking is performed in the background against the 2D profile as it has always been.

All boring bar-type tools, including any custom boring bars, are now created with the new, simplified round representation. For other tool types like General, ID groove, and ID thread, the option to create a round tool shank is available.

Wire Enhancements Mastercam X4 Wire provides a new, customized interface if your wire machining processes include using Agie EDM with Agievision controls.

Agievision Workflow In Mastercam X4 Wire’s new Agievision mode, the wirepaths and related dialog boxes are intentionally designed to closely resemble the actual Agievision interface for a familiar look and ease of use. This new Agievision support also includes a complete set of machine definition/control definition/post processor files. You can identify these files by the _AWF in the file names.

Select one of the Agievision AWF Wire Machine Definitions (WMD files) to switch Mastercam Wire into the Agievision mode. Once you switch to this mode, the Toolpaths menu shows the following wirepaths:

92 • WHAT’S NEW IN MASTERCAM X4 MU3

As you go through the pages in the wirepath dialog boxes, you will see the Agievisionspecific parameter pages that anyone familiar with the Agievision will instantly recognize.

Notes: • Mastercam X4 still includes the Agie C-Hook. This means that you can still run and maintain your current Agie C-Hook files using your current Agie machine definition and post. • Since these new Agievision wirepaths are Agievision-specific, they are not compatible with existing wirepaths that have been created with the Agie CHook. The part geometry can be reused, but all the wirepaths must be recreated using the new interface.

Post Enhancements Mastercam X4 includes a number of post enhancements that support the other new X4 features. Your \Documentation folder includes two additional resources for posts information:

 Post Debugger User’s Guide — Describes how to use the post debugger, including a tutorial example and quick reference.

 NCI & Parameter Reference — Lists all of the NCI codes and associated parameters, 20000s-series codes, and all the operation parameters. It includes procedures and examples for accessing each type of value.

Updating Posts for Mastercam X4 All posts need to be updated before they can be used with Mastercam X4. Use the UpdatePost C-Hook to update them. This is installed in your \chooks folder and is run like any other C-Hook. If you try to use a post that has not been updated, Mastercam displays an error message. UpdatePost will make the following changes to your post:

 The header will be updated with the latest version number, 13.00.  String initialization will be updated to conform to current best-practice standards. The following picture shows the new string initialization. All such statements will use the : operator, with the string value in double-quotes " ". This also applies to blank strings.

UpdatePost also includes routines that search for references to specific parameter numbers and validates them against known changes. If your original post tries to read a

94 • WHAT’S NEW IN MASTERCAM X4 MU3

parameter with a number that has changed, the following line will be written to the updatepost.log file: PARAMETER DATA - - Possibly incorrect parameter number detected: 99999. Please check the parameter number. When you see this message, look up the parameter number in the tables in the NCI & Parameter Reference and make sure that your post is actually referencing the parameter that you want. Note that UpdatePost only looks at parameter numbers in fprm tables. Postlines that are inside postblocks are not validated. Here is one example: pparameter$ if prmcode$ = 10068, z_stock = rpar(sparameter$, 1)

Support for Lathe Tool Inspection The generic lathe posts supplied with Mastercam have been modified to support the new tool inspection retract moves for lathe groove toolpaths. To implement this feature, there are two enhancements to the NCI output for lathe groove toolpaths:

 A retract move to the inspection position. This is indicated by the same 70000 cur_cflag$ (rpd_typ$ = 7) used for the Mill tool inspection feature in the surface high speed toolpaths.

 A comment that is written to the NCI just before the 70000 move. A new 29999 NCI code has been created for this comment. Unlike other 20000s lines, which are written to the NCI before the tool change line, the 29999 is written in the middle of the toolpath, at the point where the tool inspection is to take place. The following picture shows the NCI code for a lathe groove toolpath, with and without the tool inspection. You can see how the retract move and new codes are implemented.

POST ENHANCEMENTS • 95

If you are not using one of Mastercam’s generic lathe posts, you (or your reseller) will need to modify your post to properly process the new NCI codes. UpdatePost will not make these changes for you. See the NCI & Parameter Reference for detailed instructions and examples.

Agievision Support The Agievision interface introduced with Mastercam X4 includes many new dialog boxes that mimic the look and feel of the Agievision control. A new range of parameters has been established, 22000–22999, to encapsulate these settings and pass them to the post. These are then read and stored during pparameter$ like any other 20000-style parameters. This represents a significant change from how Agie data was written out by the Agie CHook used in Mastercam X3. The C-Hook wrote the data to a separate .ADT file to be read by the post, instead of the 22000 parameters. Posts written for the new Agievision interface therefore need to be completely different. The Agievision interface supplied with Mastercam X4 includes a complete post, along with a machine and control definition:

96 • WHAT’S NEW IN MASTERCAM X4 MU3

This information is used to validate the post and ensures that the selected post has been properly configured for the interface. This means that any current Agie posts (posts that had been developed to work with the Agie C-Hook) will not work with the new interface. See the NCI & Parameter Reference for detailed lists of all the new 22xxx parameters and other information about the Agievision post.

New Operation Parameters Mastercam X4 includes many new operation parameters to support the new toolpath types and other new features. These new parameters are itemized in the NCI & Parameter Reference. Traditionally, operation parameters have been numbered from 10000–19999. Since we are running out of numbers in this range, new parameters are now numbered in the 40000s.

Post Debugger Improvements The Mastercam Post Debugger, which was introduced in Mastercam X3, has several significant enhancements.

 Run Turbo mode - Lets you quickly preview your NC output so you can set breakpoints, add variables to the watch list, and otherwise identify areas of interest that you want to look at closely.

 Expanded NC Output - Lets you see each element of each NC line as it is output, and identify the specific postline element or statement that output it. In addition, the documentation has been significantly enhanced, including a quick reference, FAQ, and tutorial example. Click the new Help button on the debugger toolbar, or open the Post Debugger User’s Guide directly from the \Documentation folder.
