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 a working standby position correcting controller device to correct the working standby position such that the tool does not interfere with the object according to a diameter of the tool and a rotational angle of the axis line of the tool and set the corrected working standby position as the working standby position when the tool is held at the working standby position in a rotated state where the edge is inclined at the inclined angle with respect to the surface of the object, wherein the tool is a tool for working the object in contact therewith.
