Toolpaths: 2-D Swept
Figure 1a
STEP 1. Select MAIN MENU, FILE, GET, select 2DSWEPT.MC8 to retrieve the file for the geometry shown in Figure 1a . (If you have not created the geometry before, construct the geometry shown in Figure 1a and save it as 2DSWEPT.MC8)
STEP 2. Open 2DSWEPT.MC8 . Select MAIN MENU, TOOLPATHS, JOB SETUP.
Enter Z=0.5. Keep stock origin at the center as shown in Figure 1b. Select BOUNDING BOX, WINDOW. Create the window around the geometry and press DONE. Select DISPLAY STOCK, FIT SCREEN TO STOCK. Select Aluminum 6061-T6. Press OK.

STEP 10. In the dialog box, select the following 2D Swept Parameters as follows:
Across cut distance: 0.01
Across: Roll cutter around SHARP corners and set Cutter Compensation in Computer LEFT/RIGHT (This will be determined automatically by the computer depending on the direction of chain you selected for ACROSS).
Along: Roll cutter around SHARP corners and set Cutter Compensation in Computer LEFT/RIGHT (This will be determined automatically by the computer depending on the direction of chain you selected for ALONG)..
Cutter Diameter: 0.25 sphere.
Cutter Radius: 0.125
Stock to leave: 0.00
Rapid Depth : 1.00
Tip Comp: Center
Sync Option: None
Click OK when finished with the parameters.
