ABSTRACT:
An apparatus for machining a non-circular workpiece wherein a tool is moved by a composite movement given by a linear motor and a piezoelectric actuator. The linear motor is driven by the numerical controller in accordance with the low frequency components of profile data defining a position change of the tool with respect to angular position change of the spindle, while the piezoelectric actuator is driven by the numerical controller in accordance with the high frequency components of the profile data. Further, a positioning error of the tool due to reaction force generated by the piezoelectric actuator is detected by the numerical controller to compensate the high frequency components for the detected positioning error.
