This function is used to display any possible skid mark left on the blank as shown in Figure 8.12.1. Please refer to Section 8.1 and 8.2 for functions of other buttons.

Figure 8.12.1  Skid Mark Operation

1.       TRACE BETWEEN STEP

If the function is selected, one skid mark line per frame is displayed on the blank. Otherwise, only two skid mark lines (original and final lines) are plotted and displayed.

2.       DEFINE DRIVE LINE

This function allows the user to select the drive line(s) by cursor, select window, polygon or free hand region. The drive line is usually defined on the tool mesh (probably on the region where skid happens on the blank).

3.       EXPORT SKID LINE

This function allows the user to export the skid line to a line data file. The program displays a save file dialog window for the user to enter the file name and save the skid line in the eta/DYNAFORM Line Data format.

4.       MEASURE SKID LINE

This function is used to measure the distance between skid mark lines.

Figure 8.12.2 shows a typical plot result of Skid Mark Line. The first position is labeled with red frames and the current position is labeled with yellow frames.

5.       DEFINE PROJECT DIRECTION

This function is used to define local coordinate system and assign the project direction.
