Abstract
The present invention relates to a computer-implemented method and a planer for calculating at least one supplementary processing plan for a workpiece to be processed by a processing machine. The method comprises the steps of: Measuring workpiece properties, including a thickness parameter of the workpiece; Providing at least one supplementary processing plan, which is specific for the measured workpiece properties. Due to the present invention, measurement of the workpiece properties is performed before starting to process the workpiece. Therefore, time and material can be saved, and scrap and waste are reduced.

A computer-implemented method for calculating at least one supplementary processing plan for a sheet metal workpiece to be processed by a processing machine including a laser cutting machine and a bending machine, comprising the steps of:
- measuring workpiece properties including a material variation, the material variation including a thickness parameter of the workpiece;
- providing at least one supplementary processing plan, which is specific for the measured workpiece properties and wherein the at least one supplementary processing plan is provided before start of the processing;
- wherein the at least one supplementary processing plan is a reworked plan of a previously programmed processing plan and serves for both for cutting and bending, and
- wherein the processing of the workpiece comprises cutting and bending of the workpiece and wherein at least the cutting plan is supplemented based on the measured workpiece properties and in addition based on the bending requirements.
