To Create a 5-Axis Cut Motion Using Two Contours
1. On the NC SEQUENCE menu, click Customize.
2. Choose Automatic Cut from the drop-down list in the Customize dialog box, and click Insert.
3. On the DRIVE ALNG menu, click Two Contour.
4. The CUT MTN menu opens with Define Cut already selected, causing the CUTMOTION SETUP menu to open as well. The following commands are listed:
Parameters—Modify manufacturing parameters for the current cut motion.
Contour1—Sketch or select the first contour in the cut.
Contour2—Sketch or select the second contour in the cut.
Side Surfs—Indicate the contours of the cut by selecting side surfaces. This command is used in place of the Contour1 and Contour2 commands.
Synch—Opens the SYNCH menu for specifying points to synchronize the positions on Contour1 and Contour2.
Height—Specify the height of the cut.
Start Height—Specify the height of the first pass for multi-step Trajectory milling.
It is recommended not to use Start Height while defining a multi-axis Trajectory milling NC sequence. The tool orientation changes during the tool path generation and hence the start height, if specified can produce unpredictable results, in such cases.
Direction—Specify direction of trajectory using Flip and Okay, according to the red arrow.
Check Surfs—Select surfaces against which gouge checking will be performed.
Corners—Specify the corner conditions.
Offset—Specify the direction in which the cut motion will be offset (None, Left, or Right). The offset distance is half of the CUTTER_DIAM value. The direction of the offset is with respect to direction of trajectory; when you select an offset option, the red arrow will show the offset direction. Click Done when satisfied.
Build Cut—Access the Build Cut functionality.
Ends—Adjust the cut motion ends.
5. On the CUTMOTION SETUP menu, click Done to begin specifying the cut.  
6. The TRAJ OPT menu will appear in turn for Contour1 and Contour2; choose Sketch or Select to indicate the contour.
7. If you are creating synch points, the SYNCH menu opens with the following commands:
Add—Select a location on a contour to place a synch point.
Remove—Choose an existing synch point to delete.
Show—Display existing synch points.
Done/Return—Quit the SYNCH menu and return to defining the cut motion.
8. Choose Play Cut from the CUT MTN menu to display the cut motion.
If you get an error message "Cut motion cannot be created" try adding more synch points.
