An apparatus for machining a non-circular workpiece, wherein the profile data of plural sections of the workpiece stored in the profile data storage means are transformed into the frequency functions of 1 to n degree which is a function of the rotary angular velocity of the workpiece. The calculation means finds the amplitudes and the phases of each degree of the frequency function of each of plural intermediate sections by means of the interpolation according to the position between selected two sections based on the frequency functions of the selected two sections so as to obtain high frequency functions and low frequency functions which are then converted to high frequency and low frequency profile data. The machining apparatus actuates a linear motor in accordance with the high frequency profile data and actuates a PZT actuator in accordance with the low frequency profile data. The actuations of these actuators are accomplished in a synchronized relationship with the rotation of the workpiece to machine the workpiece into a non-circular shape whose sectional shape changes with respect to its axial position.
An apparatus for machining a non-circular workpiece wherein a workpiece is rotated at an angular velocity and a cutting tool is moved in a direction perpendicular to the rotational axis of the workpiece and a direction parallel to the rotational axis in a synchronized relationship with the rotation of the workpiece so that the workpiece may be machined into a non-circular shape whose sectional shape changes with respect to its axial position, said apparatus comprising:
