Abstract: PURPOSE: To prevent machining defects which tend to be caused at the time of transition from piercing to cutting on a hard-to-work material such as thick soft steel because of heat accumulation on a work at the time of piercing and because of the unsmooth flow of molten metal at the start of cutting.

Afterwards, fuzzy arithmetic is performed to calculate a corrected value U based on that dimension information. Consecutively, the calculated corrected value is corrected by considering its continuity.  Then, the corrected value U is transmitted to a fixed dimension device 14 and based on the corrected value U, a working machine 10 machines the work.
