1. 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 that includes cutting parameters;
extraction of a movement profile object with data relating to a movement to be performed by a laser cutting head and/or data relating to the geometry to be cut, the data relating to the geometry to be cut including data on a curvature and/or radii of a contour to be cut;
execution of a conversion algorithm during cutting to dynamically adjust the cutting parameters, said conversion algorithm is executable in a device 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 a set of functions included in a function catalogue that is stored in a memory, wherein the second cutting parameter data set is calculated using the extracted movement profile object,
wherein the cutting parameters include a cutting speed, a focus position, a pulse pattern, a nozzle distance, a gas pressure, a laser power, a beam parameter product/BPP and/or a focus diameter;
wherein said conversion algorithm calculates a function for each of the cutting parameters from the set of functions stored in the memory.
