ABSTRACT:
A circular path control apparatus and method for a multi-axis servomechanism having a plurality of driving shafts. Any disturbance to a command circular path is calculated from the amount of contour error of a circular path or a square of a circular-arc center angle error and a control for cancelling the disturbance is added, thereby improving the circular path accuracy of the multi-axis servomechanism.
