Method and control apparatus for optimized control of a machine tool

A method for generating control data for controlling a tool on a machine tool for processing a clamped-in workpiece by way of a processing process, in particular machining, wherein the machine tool comprises a control apparatus and a tool for controlling the tool in relation to the clamped-in workpiece with a three-dimensional free tool movement, said method comprising:

• generating a path program on the basis of a setpoint geometry of generated setpoint parameters for controlling the machine tool, with the path program describing a path having a plurality of supporting points and line elements, with each line element connecting to one another supporting points of a pair of the supporting points;
• controlling the machine tool in accordance with the generated path program;
• detecting actual parameters of the processing process by a feedback loop;
• iteratively optimizing the path program on the basis of the detected actual parameters for generating a new path program with a new path, with the new path program being dynamically supplied in real time during processing by the machine tool and the new path program dynamically changing and/or dynamically replacing the previous path program and the previous path during processing;
• providing a CAM functionality for changing an order of the supporting points, with the CAM functionality capable of being run in real time;
• embodying both the path program and the new path program as a CNC program, with the CNC program of the new path program changing and/or replacing a previous CNC program of the path program during processing;
• and
• running the path program to process the clamped-in workpiece.
