METHOD FOR GENERATING CONTROL COMMAND DATA FOR CONTROLLING A CNC-LATHE

摘要

A method for generating control command data for controlling a CNC-lathe to perform a turning operation by means of a turning tool (7), the method comprises the steps of: generating control command data for: commanding the turning tool (7) to go into cut at a point of the unmachined inner surface (3) which is most far away from the end position (11); and for commanding the turning tool (7) to move along the inner surface (3) towards the end position (11) until either: the turning tool (7) reaches the end position (11), or a cutting depth (8) is equal to or greater than one of either the maximum allowed cutting depth or the recommended cutting depth (5), whereby the turning tool (7) is commanded to move away from the inner surface (3), or the turning tool (7) reaches a predefined position, whereby the turning tool (7) is commanded to move away from the inner surface (3).
