To Create a 5-Axis Cut Motion Using Surfaces
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 Surface.
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.
Drive Surfaces—Define the trajectory by selecting surfaces that the tool will follow with its side. The surfaces must allow for a continuous tool path.
From/To Control—If you do not want to machine all the selected surfaces, select edges to machine. The CHAIN menu opens with the options One By One, Tangnt Chain, Bndry Chain, Surf Chain, Select, and Unselect. Using the CHAIN menu options, select edges on drive surfaces. All selected edges must form a continuous tool path. Click See Also for an example of using From/To Control.
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.
Axis Control—Apply additional control to tool axis orientation. Another way to control to the tool axis orientation is by using the AXIS_DEF_CONTROL parameter.
Corners—Specify the corner conditions.
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. The system starts the user interface for all selected options in turn.
6. Once you have specified the cut, the system displays the TRAJ PREVIEW menu with the following options:
Preview—The system shows the edges on surfaces to be machined, and displays the tool axis orientation as vectors along these edges.
From/To Control—Reselect edges on surfaces to machine, as described in Step 4.
Axis Control—Apply additional control to tool axis orientation.
If a drive surface can not be machined without gouging, the system outputs the estimated value of possible gouge in the message area at the same time as the TRAJ PREVIEW menu opens. The surfaces being gouged are highlighted and the points of possible gouge are indicated.
Another way to call up the TRAJ PREVIEW menu is to select Preview from the CUT MTN menu.
