The program automatically creates a CAM
coordinate system for each CAM segment, and the CAM
direction is W-direction. After a segment of trim line is selected from the
list, the program will automatically switch to the direction of this CAM, and
display the Rotation Result of the CAM
coordinate system under the global coordinate system.
Auto: The program provides four methods to adjust the CAM
direction automatically, as illustrated in Figure 7.5.14.

Min
Trim Angle: This function calculates the minimum
trim angle of the selected CAM segment, and uses this direction as the CAM direction.
Average
Normal: This
function calculates the average normal of the selected CAM segment, and uses
this direction as the CAM direction.
View
Direction: Define view direction as the CAM direction.

Define: Click this button to display the Vector
dialog box illustrated in Figure 7.5.15.
Refer to Section 5.1.4
Shortest Curve for detailed description about defining vector.

Manual
This function enables the CAM
coordinate system to rotate about its UVW axis, as illustrated in Figure 7.5.16. The
program utilizes the rotation about UVW axis to adjust the CAM
direction according to the defined angle in the dialog box.

Result
Display the rotation result of the current CAM coordinate system under the global coordinate system,
as illustrated in Figure 7.5.17.

Reset: Reset the CAM
direction so it can be consistent with the stamping direction (-Z-Axis)
