Abstract: A work having a non-circular cross-section is machined by relative movement between the work and a tool, as the relative position and angle between the work and tool are changed at least within a plane including the cross-section of the work. In machining along a preset tool path, the difference between the relative angle at a point on the preset tool path which machining is started and that point on the preset tool path at which machining is finished is calculated. Time needed in machining along the preset tool path is equally divided by a preset number at equal time divisions, and positions on the tool path corresponding to equal time divisions are set as tool path points. When the tool moves through each point, the relative angle is continuously changed an angle corresponding to division of the difference of the relative angles by the preset number of equal time divisions (FIG. 3).
