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.
