Abstract

A system for guiding movement of a movable machine element of a machine, such as a machine tool, production machine and robot, receives user input data relating to a travel movement of machine element and an optimization criterion selected from a robust travel movement, where a smallest number of natural frequencies of the movable machine element is excited, and a time-optimized travel movement, where from the natural frequencies of the movable machine element only those natural frequencies are excited that do not include a main natural frequency. The system then determines from the movement profile coefficients of polynomial functions and a position setpoint variable based on the coefficients. The travel movement of the machine element is executed in response to the determined position setpoint variable.
