Abstract

Apparatus for stamping and cutting a plastic part includes a housing for accommodating a stamping press. The stamping press has a lower tool part, an upper tool part, and a drive for moving the lower and upper tool parts in relation to one another. A robot having a robot arm is constructed to move into a work zone of the stamping press, when the stamping press is open and thereby enable a laser device disposed on the robot arm to perform suitable cutting operations of the plastic part.
