摘要： A numerical control device which controls a feed axis of a machine tool (10) has a storage unit (92) which divides a range of movement of the feed axis into a plurality of regions and stores a plurality of control parameters corresponding to said divided plurality of regions in advance, a position detection unit which detects a position of a feed axis at the time of machining a workpiece, a parameter selection unit (90) which reads out control parameters corresponding to a divided region to which the detected feed axis position at the time of machining a workpiece belongs, and a servo control unit (52) which controls the feed axis using said read control parameters. Due to this, it is possible to provide a numerical control method of a machine tool which realizes stable machining precision without regard as to the feed axis position and a numerical control device which conducts that method.

摘要： A speed control apparatus comprises a pulse generator (105) for generating a number of pulses proportional to an angle of rotation of a servomotor (104), a speed signal generator (107P, 107N) for converting the frequency of the pulses into a voltage indicative of the actual speed of the servomotor in order to feed back the voltage through negative feedback, a detector (106) for detecting reversal of the direction of rotation of the servomotor, a positional change detector (108P, 108N) for detecting a change in a position of the servomotor after the reversal of the direction of rotation of the servomotor by counting the pulses produced by the pulse generator, and a circuit (201 P, 201 N) for lowering the voltage indicative of an actual speed until the position of the servomotor (104) is changed through a given interval.
