Abstract

PURPOSE:To reduce a working error by correcting an NC program feeding speed specifying value from a real follow-up delay variable and a previously calculated allowable delay variable at the time of correcting the follow-up delay variable of a servo system. CONSTITUTION:A program interpreting part 2 for reading data in each block of an NC program has a data buffer 21 capable of look-ahead processing of plural block data and a function generating part 3 finds out a moving variable DELTAf per unit time of each axis. A speed correcting variable calculating part 10 is connected to the generating part 3. The calculating part 10 outputs a feeding speed correcting variable DELTA based on a difference between buffering data found out by the program interpreting part 2 and the allowable delay variable calculated by a tolerance and said moving variable DELTA is found out based on a feeding speed obtained by adding the feeding speed correcting variable DELTA to the feeding speed command value obtained from said interpreting part 2.
