Improvement of the Method for Fixing a Punch in the Punch Holder

The punching process allows large quantities of parts to be produced at very low cost. This paper studies how the technique used for fixing a punch can be improved in order to increase productivity before punch fracture, which results in large numbers of parts failing to be produced, thus creating a...
