Abstract

PURPOSE:To easily correct a feeding speed in the course of NC operation, by fetching the override amount and correcting the speed information in the course of NC command, to the speed information in the course of operation at present. CONSTITUTION:The NC control device 3 controls the NC machine tool 1 by driving the servomotor 6 for feeding the table in accordance with the NC command information stored in the storage device 4. And, when the override amount is set by the operation panel 2, and correction of the feeding speed is instructed, the NC command converting software EX fetches the override amount and the present position from the machine operation detecting device 5 and the present position counter 7, respectively, and corrects the NC command information stored in the storage device 4 in the course of execution at present. In this way, it is possible to easily correct the feeding speed in the course of NC operation.
