Abstract
In this machining method, in which a rotary tool is moved relative to a workpiece and/or the workpiece is moved relative to the rotary tool so as to machine a curved surface on said workpiece, rotation in the direction of said curved surface is added to the workpiece such that the positions of reversal marks left on the curved surface per tool path are dispersed in the direction of said rotation.
Claims10
A machining method of machining a workpiece by moving a tool relative to the workpiece, characterized in that the workpiece is machined by using essential feed axes which are indispensable to machine the workpiece and at least one surplus feed axis which is not required to machine the workpiece whereby the reversing positions of the feed motors in the respective tool paths are dispersed or the reversing motions of the feed motors are removed.
A control device for a machine tool for machining a workpiece by moving a tool relative to the workpiece, the machine tool having essential feed axes which are indispensable to machine the workpiece and at least one surplus feed axis which is not required to machine the workpiece, characterized by a superimposing section for executing the reversing position dispersing program including the movement of the surplus feed axis whereby the reversing positions of the feed motors on the machined surface of the workpiece are dispersed when executing the machining program for the essential feed axes.
