PURPOSE:To always enable uniform cutting in lathe work, by detecting the change in the diameter of a workpiece through a measuring section to cut the workpiece while modifying the position of a tool depending on the detected value. CONSTITUTION:After the cutting tip of a tool 5 is positioned in the directions of axes X, Z and the tip of the measuring member 10a of a measuring unit 10 is placed in contact with the outside surface of a workpiece 6, the cutting of the workpiece is started on a lathe. The outside diameter of the workpiece 6 is decreased with the cutting. The decrease in the outside diameter is propagated in the longitudinal direction of the workpiece 6 as the tool 5 is moved in the direction of the axis Z. The information that the measuring member 10a has been moved forth by the cut quantity of the workpiece 6 is obtained by the measuring unit 10. At the same time, a slider 8 is moved in the direction of the axis Z. According to this method, uniform cutting is always enabled. |
