The Research Of The Mould's Virtual Simulating Manufacturing System

The virtual manufacturing is a direction of industry in 21century. The virtual manufacturing technology is a renovation inindustry. It takes a bran-new idea on designing and manufacturing.It must make a far-reaching effect on industry. The virtualmanufacturing technology has not engendered a integrated theorysystem. It is a hotspot of research for the experts inside and outsidethe country. The point of building up a distributed virtualmanufacture system has been brought forward on studying of thecurrent development of industry. The primary content of this theorywas that the remote enterprises were contacted through informationtechnology and Internet technology. According to the need of themarket, a producing and management entity that has not boundingwall and beyond the space restriction was composed. Subsequentlya dynamic alliance was built up. The product was shifted to theproducing process from the design at the fastest speed and rationalcost through utilizing the resources in different area. The content ofthe virtual manufacturing technology research is very expansive. Itconcludes network technology, virtual enterprise, virtual reality,flexible manufacturing, NC technology, rapid product making andcooperated engineering etc. The virtual simulating manufacturingtechnology has been studied and a virtual simulating manufacturingsystem about the complex mould has been built in the paper. TheHAAS machine's assembly model has been built up through themodeling and the assembling for each part. The HAAS machine'sassembly mould is used as a tool for simulating manufacturing and thecomplex mould is the object to be machined. The simulating track andNC file have been obtained. The interference of the manufacturing toolhas been checked. The NC file has been applied to the real HAAS for test.An exploration on the manufacturing tool's physics simulation has also been made in the paper. The tool's distortion was simulated through building up a physical model of a milling tool. The body of the tool's bending distortion was analyzed for the asymmetry cutting force. The direction and the magnitude of the bending distortion were estimated. The error compensation was applied to this situation in order to improve the machining precision. The mould manufacturing technology developed promptly and has become an important component of modern manufacturing technology, such as the CAD/CAM technology, and the DNM technology etc. The virtual manufacturing is an important direction in the mould industry and should be studied deeply.
