<p>In the machine tool according to the present invention, a cutting tool 25 is configured to be optionally turned to take each reverse orientation, based on a C axis as the center of rotation about the Z axis, which is vertical to the X-Y plane parallel to a top face of a work 13 . First, the orientation of the cutting tool 25 is set to correspond to machining in an advancing stroke for the work 13 , so as to perform the machining for the work while moving it in an advancing direction. Then, the orientation of the cutting tool is reversed, so as to perform the machining for the work while moving it in a retracting direction.</p> |
