Method, computer program and laser cutting system for smart corner cutting

A computer-implemented method for calculating a second cutting parameter data set for controlling and/or regulating a laser cutting process for cutting metal sheets of a laser cutting machine during the laser cutting of components, having the following method steps, which are carried out on an electronic computing unit:

• acquisition of a first cutting parameter data set;
• extraction of a movement profile object with data relating to the movement to be performed by a laser cutting head and/or data relating to the geometry to be cut, in particular data on the curvature and/or radii of the contour to be cut;
• execution of a conversion algorithm during cutting to dynamically adjust the cutting parameters, said conversion algorithm is stored loadable and/or executable in a memory of the electronic computing unit, to calculate and provide the second cutting parameter data set from the acquired first cutting parameter data set by using transformation rules that are based on a function catalogue which can be stored in an external or internal memory, wherein the second cutting parameter data set is calculated as a function of the extracted movement profile object wherein the first cutting parameter data set and/or second cutting parameter data set comprises dynamic cutting parameters, namely in particular cutting speed, focus position, pulse pattern, nozzle distance, gas pressure, laser power, beam parameter product/BPP and/or focus diameter;
• wherein said conversion algorithm calculates a dedicated function for each of the dynamic cutting parameters from a set of functions stored in the memory.
