Abstract:
1. An apparatus for controlling a feedrate of a machine tool, the apparatus comprising: a processing device capable of receiving spindle parameter data, the spindle parameter data comprising a plurality of spindle parameter limits and a plurality of corresponding spindle rotational speeds; the processing device further capable of receiving a current spindle value and a current spindle rotational speed; the processing device configured to determine a respective spindle parameter limit by interpolating between the spindle parameter limits of the spindle parameter data based upon a relationship of the current spindle rotational speed to the corresponding spindle rotational speeds of the spindle parameter data, the processing device further capable of comparing the current spindle value to respective spindle parameter limit; and the processing device further capable of adjusting the feedrate of the machine tool based on the comparison between the current spindle value and the the respective spindle parameter limit.
