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, control means 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 means includes working standby position correcting means 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.
A machine tool which rotatably supports a tool for working an object to be worked such that an edge of the tool is inclined with respect to the object, in performing working of the object by the tool, holds the tool standby such that the edge is positioned at a working standby position proximal to a surface of the object and starts to move the tool from the working standby position to work the object, comprising
