| description | PROBLEM TO BE SOLVED: To provide a numerical control device capable of proper backlash correction even if behavior causing a backlash differs depending on the direction of reversal. SOLUTION: Either of three methods of outputting backlash correction amounts, i.e., a method of outputting set correction amounts at a time, a method of outputting correction amounts according to the distance traveled, and a method of outputting correction amounts as time elapses, is set as a parameter according to the direction in which movement is reversed (S3, S4). The method of outputting correction amounts at a time outputs backlash correction amounts at a time during reversal (S5, S11). When the correction amounts are outputted according to distance, a divided correction amount is outputted every time a predetermined distance B is traveled (S11, S13-S17). When the correction amounts are outputted as time elapses, divided correction amounts are outputted in a predetermined number of distribution cycles after reversal (S11, S18, S19). Since the method of outputting correction amounts can be selectively set according to the direction of reversal, optimum backlash correction can be performed if the backlash behavior of a shaft acted upon by gravity, etc., differs according to the direction.
