Abstract
An apparatus, machine tool, and method for adaptively controlling a feedrate of a machine tool are provided in which a plurality of maximum spindle power and/or radial load values, each corresponding to a spindle rotational speed, are received, stored and applied. Additionally, the current spindle power and/or the current radial load, along with the current spindle rotational speed may be received. The current spindle power and/or the current radial load may be compared to the maximum spindle power and/or radial load corresponding to the current spindle rotational speed, such that the feedrate may be reduced if the current spindle power and/or the current radial load exceed the corresponding maximum spindle power and/or radial load for the current spindle rotational speed or increased if the current spindle power and the current radial load are below the corresponding maximum spindle power and/or radial load for the current spindle rotational speed.
