CHAPTER 11

Introduction To Mastercam

OBJECTIVES In this chapter, you will learn what CAD/CAM software is and how Mastercam works. Upon completion of this chapter, you should be able to do the following: • • • • • • •

Understand the CNC Setups. Understand file types and directory structures. Start and exit Mastercam. Mastercam file functions. Import and export data to other CAD/CAM Systems. Translation - Neutral and Native. File Compression

INTRODUCTION CAD and CAM are the acronyms of Computer-Aided Design and Computer-Aided Manufacturing, respectively. CAM/CAM software is used to program CNC (Computer Numerical Control) machine tools. CAD/CAM software allows you to draw or model a part on the computer. This electronic model is accurate and can be easily modified. Machining operations can be applied to remove excessive material and to finish the part. The machining processes are accurately simulated, allowing you to find and resolve problems before running the program on the machine. Once you are certain that the machining processes are safe and effective, Mastercam performs all the tedious calculations and formatting to generate the NC (Numerical Control) code file. CAD/CAM software is often used to program CNC machine tools because it offers many advantages over manual programming, including • Faster programming • More efficient CNC programs • Fewer CNC program human errors, resulting in fewer scrapped parts and broken tools

Introduction To Mastercam

CNC SETUPS Parts must be located precisely and held securely during the machining process. Work holding devices are referred to as fixtures. A fixture can be as simple as a vise with hard jaws. Very complex fixtures, like those used in the aerospace industry, may cost many thousands of dollars and be designed by highly experienced tooling engineers. A few of the many factors influencing work holding include: • • • • • • • •

Type of material being machined Number of sides of part to machine Feature tolerances Machining forces Rigidity of the part, before and after material is machined Cost to manufacture the fixture Number of times the fixture will be used Skill level of the machine operator

For example, many parts can be accurately located and held in a vise. If the part is machined on several sides, pay careful attention to the order in which each face is machined and how the part is flipped between operations. Production quantity is an important consideration. Higher production volumes usually justify more expensive tooling to speed production and reduce scrap rate. Size and type of material and cutting forces also affect fixture choice. A foam or plastic visual prototype may be simply glued or taped down. More substantial parts can be bolted, clamped, or held with a vacuum.

CHAPTER 11

CNC Setups Vise A basic vise setup uses a vise, step jaws, vise stop, and stock material machined to size as shown in Figure 1. The back edge of the fixed step jaw is dial-indicated parallel to the machine’s X-axis. The vise stop sets a limit to slide the stock against as new stock material is loaded. Figure 1

NOTE: Improperly designed setups are extremely dangerous. Parts, tooling, or fixture components can shatter or be ejected at high speed, causing serious injury or even death. Always wear safety attire (glasses, steel toes, hearing protection, etc) and observe all machine safety procedures.

Figure 2 shows the layout of a typical VMC and the location of the spindle when the machine is at its Home Position. Figure 2

NOTE: CNC programs are written in terms of the tool tip motion, not table motion. For example, a command of X1.0 moves the tool to the right (though on a VMC the table will move to the left).

CHAPTER 11

Fixture Offsets You have probably noticed that when the machine is at its home position, its coordinate system datum is far away from the part datum. The reason is explained below. When you first power-up a CNC machine, the machine does not know where the spindle is in the workspace. The machine finds the spindle’s position, also known as the machine position, during the startup-home process by simply driving each machine axis towards its limit. Just before the machine reaches an axis limit, it trips a microswitch. This signals the control that the axis is at a known location, called the Machine Home. Home is usually defined as the center-face of the spindle where the machine is at its axes’ limits. Once a machine has been to the Machine Home, the machine keeps track of its own position by measuring how far each axis moves from Home. Coordinates in relation to the Machine Home are called Machine Coordinates. The Machine Home position is far from the work piece; hence, programs written in Machine Coordinates will have numbers that hardly exhibit obvious relations to coordinates on the part. Further, if a fixture is removed, it will be difficult to put back the fixture exactly where it was, and the CNC program written in Machine Coordinates will have to be rewritten to account for all the changes. Therefore, Machine Coordinates are rarely employed to generate CNC programs. Since a part has its own datum, NC programs can be written in reference to the Part Datum, and such programs can be easily understood. Figure 3 gives an example of the coordinate system based on the Part Datum. Figure 3

Any point on the part or fixture can be used to locate the part datum, as long as the point’s position can be reliably obtained.

Introduction To Mastercam

In Figure 4, the material is machined to the finished size before loading it into a standard six-inch vise with step jaws. The top of the finished material is the Z-Datum. The fixed (back) vise jaw is dial-indicated parallel to the machine X-axis. A Vise Stop, in this case an adjustable rod, allows stock material to be loaded into the vise in the exact same position each time. The part datum must be located precisely, typically +/- .001 or less. There are many ways to find the part datum. For example, the XY-Datum can be easily obtained using the Edge Finder to locate the back and left edges of the part. Figure 4

CHAPTER 11

Fixture Offset Registers (G54-G59) The coordinate system is shifted from Machine Home to the Part Datum by a Fixture Offset. A fixture offset is simply a record of the distance between the Machine Home position and the Part Datum point, which is kept by the machine control. Each time the NC program commands a move, the machine control checks this record, or Register, and internally adds this value to that move. G-codes that are assigned for Fixture Offset are usually G54 through G59, and some machines may allocate more. Each fixture offset has an XYZ shift value. In Figure 5, the G54 offset register is called on line (N2) of the NC program. This line of code moves the center of the spindle from the Machine Home position to directly above the Part Datum. Figure 5

CHAPTER 11

Introduction To Mastercam

Tool Length Offsets (H) You have probably noticed that the fixture offset in the previous example was used only to shift the datum in the X-Y directions, not in Z. This is because the Z shift distance changes based on the tool length - how far the tool extends below the center-face of the spindle. Most tools are of different lengths. Length may also change when you replace a worn or broken tool. Shifting the Z-datum is completed by using Tool Length Offsets. Tool offsets function similarly to fixture offsets. They inform the machine of the location of the tool tip in relation to the part Z-datum. Each tool has its own Tool Length Offset number. For most machines, Tool Length Offset number is an H-value that uses the same number as the tool (i.e., T1 uses H1, T2 uses H2, etc). The H-value is called in the G-code file with the first rapid move to depth along with a G43 (Read Tool Height Offset Register). This requests the machine to check the H-register value and add this to the move, as shown in Figure 6. Figure 6

Introduction To Mastercam

CHAPTER 11

The previous illustration presents the simplest way to use the Tool Length Offsets. This method is widely used in prototype and short production. Below is a more detailed description about the method. • The tool is jogged to the Part Z-Datum (in this case, the top of the part). • The incremental distance moved in Z-axis from the home position to the top of the part is recorded and entered in the appropriate Tool Length Register. • This value represents the shift in Z from the machine home to the Z-Datum of the part. • The value is usually negative; the machine subtracts this value from the Z-position of the spindle, shifting the tool down towards the part.

There is another method of using the Tool Length Offsets, which employs preset tooling. This method is used more often in larger companies and long production run work. A more detailed description of the method is as follows. • The tool length (distance from the center-face of the spindle to the tip of the tool) is accurately measured in the tool room. • This gage length is entered in the tool-offset register as a positive value. • The fixture offset Z-value represents the distance from the center-face of the spindle to the part Z-datum. • Internally, the control first subtracts the fixture offset from a command move. It then adds the tool gage length to the move.

NOTE: Some machines have automatic tool probes which measure the length automatically. Follow the instructions in the machine operator manual for use of tool and fixture offsets with a probe. There are other ways to use fixture and tool offsets. They all work, and companies have good reasons to adopt a particular method. But, once you understand how fixture and tool offsets work, you will easily be able to adapt to whatever method your company or school uses.

Introduction To Mastercam

CNC Setups Plate work refers to machining sheets or plates of material. The material is manufactured to a specified thickness that is the same as the finish thickness of the part. Hence no facing operation is required. The purpose of the fixture plate is to locate accurately the stock material and then keep the part from moving during machining. The illustration below shows a typical fixture plate. The fixture base is machined to be flat, square, and parallel. The plate is engraved with the part name and the coordinates of the part datum in reference to the upper-left corner, as shown in Figure 7. This makes it easier to reuse the fixture plate. Figure 7

Example Fixture Plate The fixture plate below shows the setup just before the first machining operation. After the holes are drilled and the bolts are inserted through the part, the dowel pins and clamps should be removed if there is any possibility of a collision with the tool or holder, as shown in Figure 8.

Fixture Plate Components Component Fixture Plate

Description This is the base on which the fixture is built. For short production and prototype parts, an aluminum plate is commonly used. It is machined flat, square, and parallel. Deburr all sharp edges and holes so that the stock lies flat on the surface and is not scratched.

Stock

A sheet of aluminum stock that is within specification in thickness. Since an OD contour cut is made all around the part, stock can be sheared or saw cut to approximate the size. Deburr and inspect material before placing it in the fixture.

Dowel Pins

Dowel holes are drilled and reamed to a diameter of .251 and .375 deep, providing a slip fit in the holes. A .093 vent hole is drilled from the bottom of the reamed hole through the bottom of the plate. This allows air to enter into the space between the bottom of the dowel pins. Without it, the dowel may become impossible to remove due to the vacuum created with a blind hole.

Washers Cap Screws Clamps

Page |14

Steel cap screws will mar aluminum. Place an aluminum washer or pad between clamps and an aluminum surface. Two screws hold the clamps in place during drilling operations. Others are installed to hold the plate down during the OD contour cut. Simple shop-made aluminum clamps hold the part during drilling.

Shoulder Bolts In cases where you need to position a plate with existing holes, never rely on threaded holes to locate the part. Instead, use Shoulder Bolts (aka Stripper Bolts) as shown in Figure 9. Counterbore a hole in the fixture plate the diameter of the bolt shank. Drill and tap a hole in the bottom of this counterbore to screw in the shoulder bolt. Figure 9
