Abstract
A machine tool includes: a spindle that causes a tool to rotate and move; a workpiece rotation mechanism that causes a workpiece W to rotate; a control unit that controls the spindle and the workpiece rotation mechanism in accordance with commands from a program; and a cutting load detection unit that detects a cutting load imparted on the workpiece by the tool, and the control unit controls a cutting route such that a cutting depth of the workpiece cut with the tool in a region with a small cutting load is greater than the cutting depth in a region with a large cutting load within such a range that the cutting load detected by the cutting load detection unit does not exceed a predetermined load.
Claims3
A machine tool comprising:
- a spindle that causes a tool to rotate and move;
- a motor that causes a workpiece to rotate;
- a sensor that detects a cutting load imparted on the workpiece by the tool;
- and
- a controller that controls a cutting route of the spindle such that a first cutting depth of the workpiece cut with the tool at a start of the cutting route, in a first region with a first detected cutting load, is greater than a second cutting depth before an end of the cutting route, in a second region with a second detected cutting load larger than the first cutting load, within such a range that the detected cutting load does not exceed a predetermined load.
