Abstract

A manufacturing system of the present invention comprises NC machine tools 21-2n each for processing a work in accordance with a process program having a process condition; a measuring device 3 for measuring the work processed by the NC machine tools 21-2n; and computers 5, 81-8n for modifying the process condition of the process program on the basis of a measured result from the measuring device 3. The computer 5 produces a correction data file for modifying the process condition on the basis of the measured result from the measuring device 3. The correction data file is a file that contains correction values for each of processed parts stored in variables capable of being referred directly or indirectly from the process program. The correction data file is transferred to the NC controllers 91-9n prior to the NC machine tools 21-2n processing the work. The NC controllers 91-9n modify the process condition by the process program with reference to the correction values stored in the variables of the transferred correction data file.
