<p>While being a machine tool that is not provided with a Y-axis-driving device, the present invention is capable of flat processing with an expanded processing range in the Y-axis direction, drilling in which the processing position is moved in the Y-axis direction, etc. by performing processing in a YZ plane (952), etc. using a rotating tool (67) in a specified processing range or processing position of a workpiece on the basis of a combination of a movement (y1) of the rotating tool (67), which results from an indexing action of a turret (60) driven by an indexing device, with at least one other rotation or movement selected from rotation of the workpiece by a workpiece-rotating device, movement of the rotating tool in the X-axis direction by an X-axis-driving device, and movement of the rotating tool or the workpiece in the Z-axis direction by a Z-axis-driving device.</p> |
