The fast mould integrates the systematic precision and guarantees that the system is studied
Summary : Recommend with RP fast of technology and cast maturity manufacture functional CAE system of products of craft, have analysed the factor influencing precision of the products, has proposed analysing the precision at stage of three main shaping with the non-linear finite element, adopt pattern-recognition theory, error theory, neural network method to deal with the error and feedback the problem, carry on error compensate revise and prediction of machining accuracy , improve final method of product quality.

1 preface
Fast prototype technology ( of Rapid Prototyping Manufacturing, abbreviate RP or RPM as, urged directly by the part CAD model, adopt the material accurate prototype or part manufacturing technology which piles up the complicated three-dimensional entity, it is each on the basis of being dispersed /pile up by shaping manufacturing approach not new-type of the principles. Rapid shaping technique already can make and include resin, plastics, paper, paraffin wax, pottery prototype of material successfully very much, but can only do the function experiment in the limited metal used for substituting really of occasion and other type function parts as the functional part. With increase and constant development of technology of demand, fast prototype technology to fast prototype / direction in which the part is being made develop. Utilize RP technological shaping function part, especially metal a kind of main method of part a switch technology, called the fast technology of mould(RT, Rapid tooling). Because traditional mould complicated consuming time and long costly to make course, become design and bottleneck that make often, use RP technology make fast economic mould become RP main motive force of technical development one of. Paul think from PR to RT shaping the second leap of technical development fast.
