Definitions

Punches in forming or stamping tools are used to shape a certain contour into the material to be processed, to punch a hole, to make an embossing, to extrude the material or to bend it. The contours generated are usually functionally relevant, so that punch breakage or breakouts always lead to defective parts, which must be detected as soon as possible during production.

With intelligently placed sensors, e.g. for press force or acoustic emission, many punch breakages can be detected directly on the first occurrence.
