摘要： In a numerical control device which numerically controls a machine tool having a linear axis and a rotary axis, in order to realize accurate machining by correcting translation and attitude errors which are dependent of movement of the linear axis, and those which are dependent of movement of the rotary axis, the device has: a linear axis dependent position correction amount calculating unit 6 which calculates a position correction amount of the linear axis from a translation error and an attitude error that are dependent on movement of the linear axis; a rotary axis dependent position correction amount calculating unit 7 which calculates a position correction amount of the linear axis from a translation error and an attitude error that are dependent on movement of the rotary axis; a rotary axis angle correction amount calculating unit 8 which calculates an angle correction amount of the rotary axis from a part of the attitude error that is dependent on movement of the linear axis, and a part of the attitude error that is dependent on movement of the rotary axis; and a position addition correction amount calculating unit 9 which calculates a position correction amount of the linear axis corresponding to the rotary axis correction amount.
