Abstract
A machine tool is provided with a tool mounting part mounting and holding a tool for working a workpiece, a motor rotating the tool mounting part such that an edge of the tool is inclined with respect to the workpiece, a control device holding the tool standby such that the edge of the tool is positioned at a working standby position proximal to a surface of the workpiece and starting a working movement from the working standby position. In the machine tool, the control device includes a working standby position correcting device to correct the working standby position to a corrected working standby position according to a diameter d of the tool and a rotational angle θ of the tool mounting part such that the tool does not interfere with the workpiece when the tool is held standby at the working standby position in a rotated state by the motor.
