Abstract

A method (1200) for the local forming of a malleable workpiece (106, 134), comprising: Receiving (1201) data in an input module (105) that specifies a current shape of the workpiece (106, 134); Providing (1203) a robot (102, 130, 330) which is trained to guide the workpiece (106, 134) through a machine (109); Determine (1204) a path of the robot (102, 130, 330) with a control module (104) based on the current shape of the workpiece (106, 134) and a target shape of the workpiece (106, 134); and Performing (1205) a finishing process by guiding the workpiece (106, 134) along the path through the machine (109) with the robot (102, 130, 330), wherein the machine (109) transforms the workpiece (106, 134) to the target shape.
