Switzerland Chanmier pany NCEDM with PE3 adaptive control, PCE energy control and automatic programming expert systems. Others also used the powder mixed EDM machining technology, microfinishing pulse power and fuzzy control (FC) technologies. (3) highspeed milling machine (HSM) Milling is an important means of cavity mold. The lowtemperature highspeed milling with the workpiece, cutting force is small, smooth processing, processing quality, processing efficiency (for the general milling process 5 to 10 times) and can process hard materials (60HRC) and many other advantages. Thus in the mold processing more and more attention.
