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.
A machine tool which rotatably supports a tool extending along an axis line for working an object to be worked such that an edge of the tool, at an axial end with respect to a direction of the axis line, is inclined at an inclined angle with respect to a surface of the object, which machine tool holds the tool standby such that the edge is positioned at a working standby position between a start position and a working position on a surface of the object, and starts to move the tool from the working standby position to work the object, comprising
