Abstract: The present disclosure relates to a method and apparatus for cycle-based programming of a control program for a numerically controlled machine tool at a control apparatus of the machine tool. Geometrical features, which have been detected and/or identified within a data analysis processing performed on the basis of workpiece data including a 3D workpiece model, each detected and/or identified geometrical feature being associated with a respective predetermined machining operation, are associated with a respective machine control cycle which is associated with a respective predetermined machining operation with which the respective associated geometry feature is producible.

Abstract: The invention relates to a modern method for the turning machining of appropriate machines, on which a workpiece (10) with a cutting edge (16) acts on a workpiece (18), with the machines displaying a round B axis around which the workpiece as a whole can be rotated, and a round C axis by the rotation of which the workpiece rotates around its own axis. Software developed up to now does not contain steps for providing the round axes. Thus, software is used to generate control instructions for the machine as a function of the input data which provide the geometry and position of a workpiece in reference to the resting position of a round axis and which corresponds to a respective rotation of 0° approximately. Then, software that computes certain values (cutting edge position, direction of the main cut, mounting angle, and relief angle) is attached to this software. The input data for the base software can then be derived from these values.

Abstract: By implementing a sequence control in a numerical control, tool-related machining operations and position elements are executed depending on the technology-dependent sequence in the machining program so that all cycles of a machining operation are selected consecutively as modal cycles, with all cycles being selected consecutively for a position element for each cycle for a machining operation, and the respective operation being executed at the position of the respective position element prior to the following cycle being selected as a modal cycle for an operation. Thus unnecessary tool changes are avoided and therefore machining productivity is increased.
