Abstract
A machine tool is disclosed which can suppress resonance of an in-machine robot even when vibration occurs during machining of a workpiece. Vibration of the in-machine robot is detected by a vibration sensor of the in-machine robot. When the vibration of the in-machine robot becomes greater than or equal to a threshold during machining of the workpiece, a controller changes a natural frequency of the in-machine robot by exchanging an end effector of the in-machine robot or by changing an orientation of the in-machine robot, to thereby suppress resonance of the in-machine robot.
