1、英文原文（三）At present mold technology development tendency currentIndustrial production characteristic is the product variety many, renews quick and the market competition is intense. In this kind of situation, the user the request which makes to the mold is the date of delivery short, the precision hig
2、h, the quality good, the price is low. The mold technology development will be supposed to adapt with these requests).（1） comprehensively will push in the mold design manufacture CAD/CAM/CAE the technique mold CAD/CAM/CAE technology, is a mold technological development important milestone. The pract
3、ice proved that, the mold CAD/CAM/CAE technology is the mold design manufacture development direction. Now, comprehensively popularizes the CAD/CAM/CAE technology the condition basically to be mature. Along with the microcomputer software development and the progress, the technical training work als
4、o day by day simplify. In in the popularization promotion mold CAD/CAM technology process, should hold the opportunity, key support domestic product mold software development and application; Enlarges technical training and technical service dynamics; Further expands the CAE technology the applicati
5、on scope. Has the condition the enterprise to be supposed positively to complete the mold CAD/CAM technology the deepened application work, namely the development enterprise information project, may from CAPP PDM CIMS VR, gradually deepen and the enhancement. Uses in mold design manufacture computer
6、 software, to the intellectualization, the integrated direction will develop.（2） fast prototype system （RPM）and the correlation technology will obtain well Sends Fast prototype system （RPM） the technology is US first promotes. It is following, is one kind of brand-new manufacture technology which th
7、e computer technology, the laser forming technology and the new material technology development produces, is/piles up (namely the material tired )potential forming thought based on the novel separate, according to the components CAD model, fast automatically completes the complex three dimensional e
8、ntity (model) to make. The RPM technology is the collection precision machinery manufacture, the computer, the NC technology, the laser forming technology and the materials science most recent development high tech technology, is recognized after is continues the NC technology a technological revolu
9、tion.The RPM technology may be direct or indirectly use in the mold manufacture. First is firmly conceals SLA through the three-dimensional light), folds the level solid system (LOM), the laser electoral district agglutinates (SLS), three dimensional hits minister 3D-P), fuses deposits FDM) and so o
10、n the different method to obtain the workpiece prototype. Then through some traditional fast pattern making methods, obtains the long life the metal mold or the nonmetallic low life mold. Mainly has the precision casting BR powder metallurgy, the electrolytic casting and the melt shoots (hotly spurt
11、s drips and so on the method. This method pattern making, has technological advance, the cost lower, the design manufacture cycle is short, the precision suitable medium characteristic, to the manufacture completes from the mold conceptual design, only is the tradition processing method needs the ti
12、me dish 1/3 and about cost 1/4.Therefore, the fast pattern making technology and the fast prototype manufacture technology union, will be the traditional fast pattern making technology further thorough development direction. Makes the prototype after the RPM technology, or uses the material object,
13、the use to revolve casts makes the mold with the rubber to be possible fast, the low cost to make the small batch components, the prospects for development is very good. The RPM technology also may solve the graphite electrode pressure vibration (to grind) center the female mold (electrode to grind
14、has) makes the difficult question, causes this law to obtain the new student. The Qingdao Haire mold limited company has also constructed based on RE (the reversion project technique /RPM mold parallel development system, has the development quality high, the development cost low and the development
15、 cycle is short and so on the merit.（3） the fast cut processing will obtain a more widespread application The overseas recent years developed the high speed cut processing, the main axle rotational speed might 40000-100000r/min, be quick speed may reach for the speed stabs 0-40r/min, the acceleratio
16、n may reach 1g, traded the knife time to be possible to enhance 1-2s. Like this large scale enhanced the processing efficiency, and may obtain the processing surface roughness. Moreover, but also may processdegree of hardness 60HRC the module, has formed to the electric spark forming processing challenge. The high-speed cutting processing and the tradition machining compares also has lowly (the processing work piece only to rise , the thermal deformation is small an
