Save the file as elbow1. Exercise 2 — Creating the contour toolpath This exercise shows you the basic steps for creating a toolpath and posting it to an NC file that can be read by your machine tool.
In this exercise, you will create a contour toolpath. In a contour toolpath, the tool follows the shape of a curve or chain of curves.
You will use the part you created in Exercise 1. In this exercise, you will learn the following skills: Creating a contour toolpath Chaining geometry Choosing a tool and setting toolpath parameters Selecting a tool library Using the backplot function to preview a toolpath Posting the toolpath to an NC file A toolpath can have more than one chain. If necessary, open the file from the previous exercise, elbow1.
Choose Main Menu, Toolpaths, Contour. Select the line at position 1 to start the chain. You should see the whole part highlight. To help you select the right geometry, Mastercam highlights the line when the cursor is close to it. After selecting the line properly, you will see an arrow display as shown in the following picture. Selecting a tool As soon as you finish selecting geometry for the toolpath, Mastercam automatically prompts you to select a tool and enter parameters.
Each toolpath can use only one tool. Mastercam organizes tool definitions into libraries. You can have as many libraries as you wish.
In this procedure, you will also learn how to select a different tool library. Mastercam automatically shows you the Tool parameters tab. Right-click in the large white area and choose Get tool from library as shown in the following picture. Right-click in the tool list and choose Change library. Tip: The arrow indicates the chaining direction. This is the direction the tool will move when you create the toolpath. Select the file MetricST Select the 12 mm HSS high-speed steel flat endmill as shown in the following picture.
The tool appears in the tool display area as shown in the following picture. For this toolpath, you will use the default values for all the Tool parameters, and edit the Contour parameters. Choose the Contour parameters tab. Enter a Retract height of Enter a Feed plane of 2. Enter a Depth of — Make sure your other parameters match the following picture. Rapid straight down to 2 mm above the stock the Feed plane. Because the feed plane is set to 2 mm above the part, the total plunge distance is 12 mm.
Because the compensation is set to Left, the tool will be offset from the part geometry by its radius, 6 mm. When the tool returns to the original starting point, it will rapid to the retract height, since the Rapid retract check box is selected. Choose OK to generate the toolpath. It should look like the following picture. Note: Remember that the online help has complete descriptions of all the fields, buttons, and options on each dialog box. Backplotting to view the toolpath Mastercam has two functions that you can use to preview toolpaths and operations and catch errors before you create the NC program: Backplot, which gives you a precise view of specific tool movements.
Verify, which gives you a better view of stock removal. This exercise will show you how to backplot your toolpath you will use the Verify function in the next chapter. Choose Operations to open the Operations Manager. Choose Backplot. Make sure the settings on the Backplot menu match the following picture. Choose Step from the Backplot menu or press [S] repeatedly. Mastercam will step through the toolpath. You will see a confirmation message when the backplot has finished. You can also preview the tool motion in 3D.
Choose the green Gview—Isometric button from the toolbar to look at the part in isometric view. If necessary, choose the Screen—Fit button to fit the part in the screen. Tip: To change a setting from Y to N, click on the menu option or type the underlined letter. Press [S] again to backplot through the toolpath. Now you can see the plunge and retract moves clearly. Notice that the rapid moves are in yellow and the feed moves are in light blue. When the backplot is complete, choose OK.
Exercise 3 — Making changes to the toolpath This exercise shows you how to make changes to your part or toolpath and automatically regenerate your operation. In this exercise, you will make the following changes: Edit the toolpath parameters to add entry and exit moves Change the part geometry Switch to a different tool After you've made all the changes, you will post the toolpath to an NC file.
Plunging directly into the part is not desirable because of the dwell marks left behind at the tool entry spot. In this exercise, you add entry and exit moves to the toolpath to eliminate the dwell marks. Press [Esc] to return to the Operations Manager. Choose the Parameters icon. For this part, you want to use just arcs, so enter 0 in the Line—Length field in the Entry section to disable line moves. You will use the default arc dimensions.
Choose the button to copy the Entry arc dimensions to the Exit section. Make sure your settings match the following picture. Choose OK twice. When you return to the Operations Manager, you will see a red X as shown in the following picture.
Choose the Regen Path button. Choose OK to close the Operations Manager. Choose the green Gview—Top button from the toolbar. The new toolpath should look like the following picture. You can enter the line length in either of two ways. You can type a percentage of the tool diameter here… …or type the absolute length in here. When you type a number in one field, the other automatically updates. The Arc Radius works the same way.
Choose Delete from the toolbar. Choose All, Mask. The Selection Mask dialog box lets you describe which types entities to delete. In the Entities list, choose Arcs. Choose Same as. Select any of the 10 mm fillets. When you return to the Selection Mask dialog box, you see that all of the fields are filled in with the attributes of the 10 mm fillet.
Mastercam will use this mask to select all of the fillets and delete them. Choose Yes at the confirmation prompt. Create 6 mm fillets in all of the gaps. See page 24 if you don't remember how to create fillets. Since the fillets are now smaller and the same radius as the tool, you will switch to a smaller tool so you can get smoother tool motion around the fillets. Choose the Tool parameters tab. Right-click in the tool display area and choose Get tool from library.
Choose OK again to return to the Operations Manager. Choose Regen Path to regenerate the toolpath with the new tool and new geometry. The act of making this file called an NC program is called post processing, or posting. When you post a file, Mastercam runs a special program called a post processor that reads your Mastercam file and creates an NC program from it. Your original Mastercam file isn't changed.
Choose Post. The Operations Manager window should still be open. Select the Save NC file check box, and choose the Edit option. Choose the Ask option this means that it will prompt you for a file name. If the correct post processor was not used, you could crash your machine tool and cause serious injury or damage.
Do NOT assume that the post processor shown in these examples is compatible with your own machine tool. Type in a file name when prompted. If you wish, you can navigate to a different folder; the default is Mcam9MillNc.
Choose Save when you are done. Tip: Check your machine tool or control documentation to see what file names are allowed. For example, you might be limited to 8 characters or less. After you save the file, it will appear in a text-editing window so you can review it or make changes, as shown in the following picture.
Post processors are machine- and control-specific. When you installed Mastercam, you selected a default post processor. The current post processor is listed here. If you need to, you can select a different one by choosing Change Post.
Close the NC program window to return to Mastercam. Setting the default tool library The remaining exercises in this tutorial will use tools from the MetricST In this procedure, you will make this the default tool library, so that you do not have to keep selecting it. Choose Main Menu, Screen, Configure. Choose the Files tab. Choose Tool library in the File usage list.
TL9 appears in the File name field as shown in the following picture. If it doesn't, choose the File button and select it. Choose Save As to save the setting to the configuration file. Choose Save. Choose Yes when asked to overwrite the current file. You've now seen all the major stages of creating a part and an operation to machine it.
In the next chapter, you will use the simple operation you created in this chapter as a building block for more sophisticated operations. You will create the following new operations: Finishing and multi-pass roughing operations A chamfering operation A mirrored copy of the operation The part used in this chapter is the same one that you saved at the end of Chapter 3.
If you did not complete Chapter 3, use the file new elbow- mm. Exercise 1 — Creating roughing and finishing passes The 2D contour toolpath you created in the previous chapter only has a single cutting pass. You decide that it takes off too much stock for a single pass, so you decide to rough out the part in multiple passes with a larger tool.
You will complete the part with a separate finishing operation. In this exercise, you will use the following skills: Copying operations Creating multiple passes Creating finishing operations Changing tools and feed rates Copying operations To create the separate operations for roughing and finishing with the minimum number of steps, you will copy the current 2D contour operation and then edit the parameters for each copy.
If necessary, open the part file you saved at the end of Chapter 3. If you did not complete Chapter 3, choose File, Get from the menu, and open the file new elbow-mm. Right-click on the Contour folder icon and drag it below the NCI icon. Release the mouse button and choose Copy after. A copy of the operation appears as shown in the following picture.
Click on the name of the first operation until it highlights for editing, and type in a new name: Rough 6. Repeat for the second operation and type the new name: Finish.
The operations should look like the following picture. Setting the roughing parameters To make the first operation a true roughing operation, you will select a bigger tool for it and specify multiple passes.
Choose the Parameters icon for the Rough operation. Since this is a roughing pass, you should leave some stock for the finish operation. Enter 1 in the XY stock to leave field. Your contour parameters should match the following picture. Select the Multi passes check box and button. Enter 2 for the Number of Roughing passes and select Keep tool down.
The rest of the values should match the following picture. Enter an Overlap of 5. This means that the entry and exit arcs will overlap by this distance. Choose the button to copy the settings to the Exit section. Your values should match the following picture. Setting the finish parameters Since the second operation will be a finish operation, you will keep the original tool, but will use a slower feed rate.
Choose the Parameters icon for the Finish operation. Enter a Feed rate of Enter an Overlap value of 5. Make sure the other values match the following picture. Choose OK twice to return to the Operations Manager. Choose Select All. Choose Regen Path to regenerate both operations with the new parameters.
The new toolpaths should look like the following picture. Make sure both operations are still selected as shown in the following picture. Set the Verify option to Y. Press [S] to step through the toolpath. Notice how the stock is removed after each pass, and how the finish tool cleans out the areas that the roughing tool cannot reach.
The following picture shows you a snapshot midway through the final finish operation. You can see the stock left by the roughing operation and how the finish operation is cutting right to the blueprint dimension. Tip: The blue check marks indicate which operations are selected. Press OK when the backplot is finished. Choose Main Menu, File, Save and save the file in your working folder as elbow2.
Exercise 2 — Creating a contour chamfer Next, you would like to add a chamfer to the contour. Mastercam has contour toolpath options that let you easily create a chamfer by specifying some simple dimensions. You will create a separate operation for the chamfer that uses a chamfer tool.
You will learn the following skills: Creating 2D chamfer operations Using the Verify feature to preview stock removal Creating the chamfer operation You will create the chamfer operation in the same way that you created the finishing operation in the previous exercise, by copying an existing operation and editing its parameters.
Make a copy of the Finish operation and name the copy Chamfer. See page 45 if you don't remember how to do this. Choose the Parameters icon for the new Chamfer operation. Select the 10 mm HSS chamfer mill from the tool library. In the Contour type drop-down list, select 2D chamfer. Choose the Chamfer button. Enter 1 for the Width, and 2. Your selections should match the following picture. Choose OK to return to the Contour parameters dialog box. Enter 0.
The actual cutting depth achieved by the chamfer mill is determined by the width and tip offset you entered in step 9. Your contour settings should match the following picture. Choose OK to return to the Operations Manager. Choose Regen Path to create the toolpath. Using the Verify feature to preview stock removal In previous exercises, you used the Backplot function to preview toolpath motion.
In this exercise, you will use the Verify function in the Operations Manager instead. This function gives you a better picture of the 3D part. While inside the Operations Manager, choose Select All so you can verify all the operations.
Choose Verify. Choose the button to set the Verify configuration. Enter 0 for the Z—Max point. Choose the button. Choose the button on the Verify toolbar to end the Verify session and return to the Operations Manager. Exercise 3 — Mirroring the part and toolpath You are required to manufacture both left-hand and right-hand versions of the part. You can do this by mirroring the part and toolpath. This lets you maintain the original toolpath parameters and machining direction for all the operations, ensuring that the duplicated part has the identical finish and size as the original.
In this exercise, you will learn the following skills: Creating mirror images of parts and toolpaths Re-ordering operations in the Operations Manager for greater machining efficiency Mirroring the part 1. Press the [Page Down] key several times to zoom out from the part. Right-click anywhere in the graphics window and choose Dynamic Pan from the menu. Click and drag to the right until the part is at the right edge of the screen. Click again to exit dynamic panning. Press [F9] to display the coordinate axes.
Choose Toolpath Group 1. This selects all the operations. Choose Type—Mirror. Choose Create new operations and geometry. Make sure your other selections should match the following picture.
Choose the Mirror tab. Choose Reverse toolpath. The original toolpath used climb milling; selecting Reverse toolpath means that the mirrored part will also use climb milling, so the finish on both parts will match. The Mirror tab should match the following picture.
The part and toolpaths should look like the following picture. The way the operations are ordered now, Mastercam will rough the first part, then finish and chamfer it before roughing the second part, resulting in unnecessary tool changes. In this procedure, you will rearrange the operations so that the roughing, finishing, and chamfering operations are grouped to minimize tool changes.
You can see the new operations 4, 5, and 6. Click and drag the corner of the Operations Manager window as shown in the preceding picture to make it larger, so you can see all the operations. Click on the second rough operation Operation 4 and drag it on top of the first rough operation.
Click on the second finish operation and drag it on top of the first finish operation. Your operations should be in the following order. Choose Select All, Backplot. Choose Run.
You should see the operations machined in the proper order. When the backplot is finished, close the Operations Manager and save the file. In this chapter, you saw how to mirror parts and toolpaths. In the next chapter, you'll learn techniques for rotating geometry and operations around a center point so you can easily draw and machine circular parts.
After you create the part, you will learn how to rotate toolpaths as well. Exercise 1 — Creating the geometry In this exercise, you will design a wheel with three symmetrical slots as shown in the following blueprint.
You will use the following skills: Creating arcs, tangent arcs, and lines Rotating geometry Trimming geometry If necessary, create a new file. Enter for the diameter. Press [O] to select the origin for the center point. Note: Press the letter "O," not zero. Enter 40 for the diameter of the inner circle.
Press [O] again to select the origin for the center point. Press [Esc] to exit the Create Arc function. Right-click anywhere in the graphics window and choose Fit screen from the menu. Creating construction lines for the slot To rough out the slot, begin by defining the vertical edges, then rotating to the proper position. Select at position 1 then at position 2 these are only approximate positions to draw the construction guide. Enter 10 for the X coordinate of the line.
Create a second vertical line by selecting near positions 1 and 2 again. Enter —10 for the X coordinate of the line. Next, you will rotate one of the lines to form the other edge of a slot. Select the left line. Choose Done, Origin. Choose Operation—Copy. Enter a Rotation angle of The line should rotate as shown in the following picture. Creating the arcs for the slot outline Create the inner and outer curves along with the fillet arcs for one of the slots. Press [O] to select the origin as the center point.
Type in the radius of the outer arc: 80 4. Click near positions 1 and 2 in the following picture to locate the approximate starting and ending angles of the outer arc. Note: Mastercam measures all arcs in a counterclockwise direction. To create the inner arc, type [O] again to locate its center point at the origin. Enter its radius: 40 7. Click near positions 3 and 4 in the previous picture to locate the arc's endpoints. Now create 12 mm fillets at the four corners of the slot.
Enter 12 for the radius. Click on the positions shown in the following picture in order. Completing the first slot To complete the first slot, you need to create the flat edge on the outside radius.
First you will create the horizontal line. Then you will rotate it into position and create the arcs that connect it to the slot. Enter the coordinates for the first endpoint: — Enter the coordinates for the second endpoint: The line should look like the following picture.
Select the horizontal line you just created. Choose Operation—Move. Enter a Rotation angle of — The line should rotate into position as shown in the following picture.
Zoom in on the new line. Right-click anywhere in the graphics window and choose Zoom window. Click once near position 1 and then near position 2. Select the arc at position 1. Select the endpoint of the line at position 2.
Enter the radius of the arc: 12 Since there are several possible arcs through the endpoint of the line and tangent to the arc, Mastercam asks you to select the one you want to keep. Repeat steps 12—15 to create the arc at the other endpoint of the line. Use Mastercam's Trim function to delete the segment of the outer radius between the two arcs. Select the arcs at positions 1, 2, and 3 as shown in the following picture.
Delete the construction line shown at position 4. Press [Page Down] to unzoom, if necessary. Creating the other slots by rotating the first slot Now that you've created the first slot, copy and rotate it about the center point to create the other two slots.
Fit the part to the screen. Click anywhere on the slot. Choose Done, Done, Origin. In the Rotate dialog box, choose Operation—Copy. Enter 2 for Number of steps. Save the file in your working folder as slotted wheel. You will cut around the inside contour to cut the slot out completely, instead of cutting it as a pocket.
You will create a toolpath for the first slot, and then add the other slots to it. You will learn the following skills: Cutting an inside contour Adding more geometry to an existing toolpath Creating the toolpath 1. Select the start point for the chain at position 1. The chaining direction arrow should point counterclockwise. If it doesn't, choose Reverse from the menu. Select the 10 mm HSS flat endmill from the tool library.
Select the Contour parameters tab. The part is 12 mm thick, and you will cut through an additional 3 mm. Your other parameters should match the following picture. Enter 0 for Entry Line—Length. Enter 12 for Entry Arc—Radius. Choose the button to copy the entry arc dimensions to the Exit section.
The toolpath should look like the following picture. Choose the Geometry icon for the toolpath. Right-click on Chain 1 and choose Add chain from the menu. Click on locations 1 and 2 in the following picture to add the other two slots to the toolpath. After selecting each slot, the chaining arrow should be pointing counterclockwise. If it does not, choose Reverse from the menu. The Chain Manager displays the chains for all three slots.
Choose Regen Path. Choose OK after the toolpath has been regenerated. Exercise 3 — Rotating a toolpath The part shown in the following picture has 30 identical slots. In this exercise, you will create a toolpath for a single slot and, instead of rotating and copying the slot, you will rotate the toolpath. Using this approach to machine the other slots means that you don't have to create geometry for them. Open the file rotation-mm. Select the start point of the chain at position 1.
The chain direction should be counterclockwise. Select a 6 mm HSS flat endmill from the tool library. Enter a Depth of —6. The rest of the parameters should match the following picture. Choose the Multi passes check box and button. You will create a single roughing pass and a single finishing pass.
Enter 1 for the Roughing passes—Number and 1. Enter 1 for the Finishing passes—Number and 1 for Spacing. Select Keep tool down. This ensures that the entry and exit move will take place in the middle of the slot, instead of at the narrow end where there isn't enough room. Enter 0 for the Entry Line—Length.
Enter 3 for the Entry Arc—Radius. All you need for an entry arc is a partial arc, so enter 45 for the Entry Arc—Sweep. Mastercam generates the toolpath shown in the following picture. Rotating the toolpath 1.
Choose Next menu, Transform. Choose Type—Rotate. Choose Method—Coordinate. This means that each rotated toolpath will be generated by calculating the coordinates of each slot within the same plane, rather than by shifting the orientation of the tool and part for each successive slot.
Choose the Rotate tab. Choose Origin for the Rotate point. Enter 29 for the Number of steps. All of the tool movements for the 29 other slots are contained in the single Transform operation as shown in the following picture. Save the file as rotation1. This procedure shows you how to cut the multiple slots when you are using a rotary indexer to rotate the part.
Choose the Parameters icon for the Transform operation. Change the transform method to Tool plane. Select the Subprogram option. Make sure that Incremental is selected. Note: Some posts may not support subprograms. If your post does not, leave the Subprogram option unchecked. Choose Select All, Post. If necessary, choose Change Post and select the proper post for your machine.
Make sure your other values match the following dialog box and choose OK. When prompted, save the NC file as indexer. When the NC program appears in the editor window, scroll down until you see the lines shown in the following picture. You can see the A codes used to increment the indexer.
Close the editor window. You've now seen a number of techniques for creating 2D geometry and toolpaths. The next chapter introduces you to creating 3D geometry and toolpaths.
