PURPOSE:To improve the overall working by detecting errors with prescribed intervals, operating correctly an NC machine by means of the error data and at the same time correcting the data when the prescribed conditions are satisfied. CONSTITUTION:A main control part 31 of a controller for NC machine extracts the desired programs and data out of a program part 32 and performs the integrated control of each control part, etc. A gate control part 33 of an individual parts supply part contains a loader/unloader control part 34, a head control part 35, a table control part 36 and an input control part 37. The part 32 stores an NC program and a program for correction of the NC program. Thus the NC program is corrected. Here the position shift is detected between the worked materials positioned with a prescribed space. Then it is decided based on said position shift whether the data on a prescribed position should be corrected or not. When this deciding frequency reaches a prescribed level, the position data is corrected and fed back to an NC program.
