Abstract
A method of generating a smooth curve to perform interpolation from a commanded sequence of points by a numerical controller for a multi-axis machine tool having three linear axes and two or more rotary axes. Corrected command points are obtained for linear axes and for rotary axes. Components of corrected command points for linear axes and corrected command points for rotary axes are synthesized with each other so as to obtain a synthesized corrected command point. A curve passing through the synthesized corrected command points is generated to perform interpolation. As a result, a more appropriate curve interpolation method for a multi-axis machine tool having two or more rotary axes can be performed.
