Die Interference Detection

Here is an example of a stripper with the strip resting upon it. The stripper has milled pockets to provide clearance for the flanges which are already formed upward.

Stripper with interference

Interference detection with the milled pockets in stripper indicate that the pockets are too shallow and that the strip will make contact and distort the flange. If this wasn't discovered until die try-out, you would be removing the stripper and re-milling the pockets at the last minute wasting valuable time. Notice the list on the left hand side which shows areas of contact.

Stripper with no interference

This picture shows interference detection with .125” deeper pockets in the stripper. As you can see, the list on the left shows no interference.
