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.

Figure 7.5.14  Auto

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.

User 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.

Rotation 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)
