, threedimensional, intelligent and work direction (1) mold software features integrated Die software features of integrated software modules required relatively plete, while the function module using the same data model, in order to achieve Syndicated news management and sharing of information to support the mold design, manufacture, assembly, inspection, testing and production management of the entire process to achieve optimal benefits. Series such as the UK Delcam39。 laminated profile manufacturing (LOM)。 to create the best management and effective teamwork, lean production。 by the general diffusion to the CVD, PVD, PCVD, ion peration , the direction of ion implantation, etc.。s AQ325L, AQ550LLSWEDM have driven fast response, transmission and high positioning accuracy, the advantages of small thermal deformation. 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. Ruishikelang pany UCP710type fiveaxis machining center, machine tool positioning accuracy up to 8μm, homemade closedloop vector control spindle with a maximum speed 42020r/min.
