This function allows the user to check the distance between the specified tool and blank. It would help the user to see the contact condition during forming by animating the distance between blank and tool. Figure 8.10.1 shows the control window of the function. Refer to Section 8.1 and 8.2 for a description of other buttons.

Figure 8.10.1  Blank/Tool Distance

1.       NORM DIRECTION

If this option is selected, the distance between blank and tool will be checked along the normal direction of the selected tool. Otherwise, the distance will be checked along the tool motion direction.

2.       DEFINE TOOL

This function allows the user to select the tool for calculating distance. The program displays the Select Part Control Option window, as shown in Figure 8.10.2.

Figure 8.10.2  Select Part Control Option

Users can select tool(s) by cursor, select window, polygon and free hand region.

3.       BLANK BY ELEMENT (calculating distance region)

This function allows the user to select element(s) of the blank by cursor, select window, polygon and free hand region.

The user can simulate the distance between blank and tool after defining the tool(s). Figure 8.10.3 shows a typical plot of distance between the blank and tool during the initial forming.
