Abstract
A punch is provided with a detection system for evaluating crack defects in waste material removed during a clipping operation. The punch includes a clip ring and a clip insert for shearing excess material from a part processed therein. The excess material is engaged around the clip ring when sheared from the part. Frictional resistance between the waste material and the clip ring is evaluated in determining potential crack defects in the waste material.
