This function is used to check the contact between reference blank (copy from binder) and punch during drawing. Click this button to display the Contact Check dialog box illustrated in Figure 7.2.36. Copy the existing binder in the position of the initial contact between blank and punch as reference blank and move the reference blank along the stamping direction, as illustrated in Figure 7.2.37.

 Move the reference blank to the initial contact position.

 Move the reference blank with a given STEP along the initial contact direction.

 Move the reference blank with a given STEP along the closing direction.

 Move the reference blank to the closed position.

 Move the reference blank to the initial contact position.

 Move the reference blank with a given Step along the initial contact direction.

STEP

Movement step.

FROM CONTACT

The distance between reference blank position and the initial contact point.

FROM CLOSED

The distance between reference blank position and the closed position.

DRAW DEPTH

The maximum draw depth between binder and punch. When the die and punch are closed, take the first contact point of reference blank and punch as the reference point. The maximum draw depth is obtained by calculating the draw depths between this reference point and all points on the binder.
