Abstract:
A method for setting a moving position of at least one of a workpiece and a tool in a machine tool for machining the workpiece rotated around a predetermined axis into a desired shape by the tool, comprising:dividing a contour shape of the desired shape at section along the predetermined axis into a plurality of machining units, each including a plurality of inflection points including a machining unit start point and a machining unit end point; setting machining data including at least machining speed data for each of the machining units; calculating an arrival time at each of the inflection points based on the machining speed data; calculating a position of at least one of the workpiece and the tool at each of the inflection points; and setting a rotation angle position of the workpiece corresponding to the arrival time as an accumulated count value for each of the machining units.
