Claim 0:
1. A computer-implemented method for calculating process parameters, being laser cutting parameters, which are machine and material specifically optimized for laser cutting a workpiece, being a sheet metal, with specific material properties by means of a laser machine with specific machine properties, comprising the method steps of:
Determining at least one of material of the workpiece and/or machine properties for which the process parameters are to be optimized;
Determining preconfigured initial process parameters;
Executing a re-optimization algorithm based on a statistical model accessed from a storage, and optimizing the process parameters based on the at least one of determined material of the workpiece and/or machine properties until a target objective function is achieved; and
Controlling a laser cutting process for the workpiece with the optimized process parameters, wherein execution of the re-optimization algorithm comprises:
Controlling execution of test processes with the determined preconfigured initial process parameters;
Evaluating the test processes by using a measurement-based algorithm or a preference-based algorithm for determining preferences for the test processes; and
Re-defining a parameter domain for the re-optimization algorithm based on the determined preferences.
