Abstract
A method for making a blind hole may include arranging a workpiece in a negative form with a first portion and a second portion. The first portion may include a recess. The second portion may include a guide for a punch. The recess may be arranged substantially coaxially to the guide. The method may also include displacing a material of the workpiece into the recess via pressing the punch into the workpiece. Additionally, the method may include pressing the punch into the workpiece in a first movement section with a first velocity. The method may further include further pressing the punch into the workpiece in a second movement section with a second velocity such that the material is sheared and is partly extruded into the recess. The method may include moving the first portion relative to the second portion and shearing off the material displaced within the recess.
