    摘要： A numerically controlled machine tool which has a linear feed axis (X,Y,Z) and a rotational feed axis (A,B,C) and which has functions for measuring in advance, errors of a relative position and a relative attitude of a main spindle (4) relative to a work table (6) by positioning the linear feed axis (X,Y,Z) and the rotational feed axis (A,B,C) to specified position and attitude, and correcting a movement command based on measured error data (34), the error data (34) being multidimensional data containing a position error (34a) and an attitude error (34b). The machine tool includes a error data storage means (25) which store an error map that is prepared by collecting a plurality of the error data (34) corresponding to positions and rotation angles of the linear feed axis (X,Y,Z) and the rotational feed axis (A,B,C), and a correction data computing means (26) which compute correction data for correcting the movement command from a command position for the linear feed axis (X,Y,Z) and the rotational feed axis (A,B,C) and the error data (34) stored in the error data storage means (25).
