Application in trial-producing owing to fleetness molding technology backing project and fleetness moulding unfinished products Abstract: Have introduced application in trial-producing owing to that integrated environment of RP & RT backing project and fleetness mould make the technology method unfinished products , have discussed owing to that integrated environment of RP & RT backing project and fleetness mould create the key technology developing, prospect having looked into the distance owing to that the integrated environment of RP & RT fleetness mould makes Keywords: Fleetness molding technology (RP); The fleetness mould makes a technology (RT); Backing project (RE); Integrated environment of RP & RT Abstract keyword: Rapid Prototyping; Rapid Tooling; Reverse engineering 0 forewords: Fleetness molding makes the technology (RP) being able to adapt to small batches of especially single document of various turn out type moulds give birth to a child , can also adapt to various complicated degree mould fabrication not only. Both being able to make the plastic mould and, can make the die-casting model waiting for the metal mould it. The molding technology once comes out therefore rapidly , prompt apply to the mould make is listed in. The mould applying the fleetness molding method fleetness making the mould technology being called a fleetness makes (RT) a technology , the mould makes but owing to fleetness molding (RP) technology fleetness since integrated degree of technology is high, conversion process is from CAD data to physics entity quick , the numerical control job operation with tradition is compared with each other as a result , the period processing a piece of the mould fabrication is 1/ 3 ~ of the former only 1/10, cost of production is 1/3 ~ also only 1/5. . 1 summarizes: The technology studying and developing a mould, improves mould engineering level, to boosting development of national economy having especially important significance. The mould is praised the motive power , being to enter better-off society by Japan before Germany be emperor in being metal processing industry of crown, look upon as a mould in Romania being a gold , a few developed countries are called magnetic force industry other in Europe and America. One may predict that, with the commercial run promptness develops , mould industry develops process Lieutenant General in national economy bringing the more and more important effect into play. The key that 1.1 mould industry general situations mould industry develops is mould technology progress , the mould technology is one to deal with multidisciplinary inter-disciplines. The mould is one kind of high added-value and skilled-intensive products , whose engineering level height already has become judging one country creates one of horizontal important sign. The basic that 1.2 moulds create demands in the industrial product turn out , the purpose applying a mould's lies in guarantee product mass , improves efficacy and cost reduction. Therefore, carry out design for die and mould except rightness , adopt the rational mould structure outside , must mould having height mass as guarantee making a technology. 1.3 moulds make the technology developing trend fleetness prototype + fleetness mould technology having provided a new concept and method making a mould directly from the mould CAD model , it designs the mould concept with the integration processing handicraft within a CAD/CAM system , are that realizing the parallel project has created favorable condition. The fleetness mould technology adopt fleetness prototype early phase , multiloop , fleetness information feedback design and creates method, link various computer imitate with analytical means, the brand-new design for die and mould having formed one package and creates system.
