When warm-up operation is started, a machine tool acquires an atmospheric temperature around the machine tool and selects a warm-up operation program on the basis of the acquired atmospheric temperature. A warm-up operation command suitable for the atmospheric temperature is given to the control unit according to the selected warm-up operation program. A movable unit of the machine tool can be thereby controlled, and optimum warm-up operation for the atmospheric temperature can be eventually performed. |
