【正文】 o the market professional collaboration from mass production。 in the 1990s, due to the introduction of the CNC machine tools, edm, etc more advanced equipment, a significant improvement in the level of the production process of the die, the production cycle and die of quality has been greatly reduced and improvements. Highprecision machining have put workers from hard manual labor. On the other hand, cad/cam/cae, puteraided technologies in the die and mould industry are also a wide range of applications, die design and NC processing level have greatly increased, cad/cam/CAE software for die technician productivity and reliability has improved. Currently all die enterprises are faced with a new topic, how to put the enterprise management also from mundane transaction liberated, let the information management for the enterprise productivity. So die enterprise management of information technology have bee the die and mould industry development and progress of the inevitable trend. Mold is a single order production, the management has the particularity of their strong. Design is part of the manufacturing, process design is not sufficient, design and technology information to direct reuse value. Therefore, according to enterprise production features grasp information management and practical, simplified management of balance, is the key to information technology. This creates very difficult reproduces the mature management software. For example car die enterprises do not have the traditional sense of the raw materials, warehouse management, and so on. The acquisition is part of and part of semifinished products, does not exist as finished out of the library processes, manufacturing cost amortization every business is different. As another example cost accounting should adopt measures for the management of projects, rather than adopt a general manufacturing methods, what pdm, erp, and other software without thorough reform is not. 1 modern die design CAD/CAE applications Die design with industrial product parts of shapes, sizes and dimensional accuracy and surface quality requirements, as well as the forming process conditions changes, so every die must be creative design. Die design of content including product parts (often referred to as parts) forming process optimization and mechanical calculation and dimensions and dimensional accuracy to determine and design, and so on, so die design often divided into parts process analysis and design, mold design, architecture design, design of four stages. CAD/CAE, puteraided design and secondary works, it includes conceptual design, optimization, finite element analysis, puter simulation, puteraided drawing and puteraided design process management. Using CAD technology can design a product of the general structure, and then by CAE for structural analysis, feasibility and design optimization。s concept design is more than just stay on appearance and structure of the design, it has expanded to mold the field of structural analysis. For the use of CAD technology designed by mold, you can use advanced CAE software (particularly finite element software) on its strength, stiffness, highimpact test simulation, drop test simulation, thermal capacity, fatigue, and creep such analysis. Through these analyses, you can test the design on the front of the conceptual structure is reasonable, analysis of the structure of the cause and location, and then in the CAD software modify it accordingly. The modified again in CAE in a variety of performance testing, the final determination of the mould structure that will meet all your needs.Today39。s thinking, system modules also incorporate the general concept design concepts and methods. At present, the world39。s processing simulation features detailed simulation, parts, tools and toolholders, fixtures, platform and tool movement speed, paths, and so on appear, to observe the entire mould parts of the cutting process and the shapes, which in turn before and after checking the correctness of the program, this is a plex surface mold is particularly important.(2) die parts in addition to highprecision geometry requirements, its shape and position accuracy requirements are relatively high, General Gage is difficult to achieve the ideal purpose, this will depend on the precision parts measurement system. This precision parts measurement system (CMM, . Coordinate Measuring Maching, CNC machining centers of a warp. Its measurement accuracy of up to μ m, its measure follows: CAD/CAM system via or CMM dedicated software produces parts data field to CMM puter system, through the appropriate setting, . in accordance with the data to measure the workpiece, findings and the original data parison results after processing error.。模具企業(yè)必須利用最新的技術(shù),在最短的時(shí)間內(nèi)開發(fā)出高質(zhì)量、低成本、高附加值的產(chǎn)品,以最快的速度響應(yīng)和投放市場(chǎng)。 　　關(guān)鍵詞:現(xiàn)代模具。制造。傳統(tǒng)模具產(chǎn)品開發(fā)從設(shè)計(jì)、試制到產(chǎn)品上市周期太長,設(shè)計(jì)過程中難以與用戶進(jìn)行交流,難以及時(shí)聽取用戶的意見,難以考慮可制造性和可裝配性,很難全面考慮安全、維護(hù)等方面的要求,不能綜合考慮生產(chǎn)、時(shí)間以及費(fèi)用等相互制約條件的限制,更談不上考慮整個(gè)模具產(chǎn)品壽命周期的諸多問題。 　　 　　1現(xiàn)代模具設(shè)計(jì)與制造已步入信息化時(shí)代 　　 　　改革開放30多年來,中國模具生產(chǎn)作為一個(gè)產(chǎn)業(yè)有了翻天覆地的變化。大多數(shù)人看到的是中國模具產(chǎn)業(yè)作為一個(gè)行業(yè)的從無到有、從小到大、從拾漏補(bǔ)缺到成為主力,以及模具需求和產(chǎn)量的快速增長變化。后兩種變化是一種更加深刻、更加根本性的變化。從完全非標(biāo)生產(chǎn)到相對(duì)標(biāo)準(zhǔn)化和準(zhǔn)標(biāo)準(zhǔn)化生產(chǎn)。 　　20世紀(jì)80年代前,很多模具是靠鉗工用手打磨出來的。高精度加工己經(jīng)把工人從繁重的體力勞動(dòng)中解放出來。目前各模具企業(yè)又面臨著一個(gè)新的課題,如何把企業(yè)管理也同樣從煩瑣的事務(wù)中解放出來,讓信息化管理為企業(yè)的生產(chǎn)效率提升作出貢獻(xiàn)。 　　模具生產(chǎn)是單件訂單式生產(chǎn),在管理信息化中有其強(qiáng)烈的特殊性。因此,根據(jù)企業(yè)生產(chǎn)特點(diǎn)把握全面信息化管理與實(shí)用、簡(jiǎn)化管理的平衡點(diǎn),是信息化的關(guān)鍵。例如汽車模具企業(yè)沒有傳統(tǒng)意義上的原材料,倉庫管理等等。又比如成本核算更應(yīng)該采用項(xiàng)目管理的辦法,而不是采用一般加工制造業(yè)的辦法,什么pdm、erp等軟件不經(jīng)過徹底的改造是完全不適應(yīng)的。模具設(shè)計(jì)的內(nèi)容包括產(chǎn)品零件(常稱為制件)成型工藝優(yōu)化設(shè)計(jì)與力學(xué)計(jì)算和尺寸與尺寸精度確定與設(shè)計(jì)等,因此模具設(shè)計(jì)常分為制件工藝分析與設(shè)計(jì)、模具總體方案設(shè)計(jì)、總體結(jié)構(gòu)設(shè)計(jì)、施工圖設(shè)計(jì)四個(gè)階段。應(yīng)用CAD技術(shù)可以設(shè)計(jì)出產(chǎn)品的大體結(jié)構(gòu),再通過CAE技術(shù)進(jìn)行結(jié)構(gòu)分析、可行性評(píng)估和優(yōu)化設(shè)計(jì)。借助于計(jì)算機(jī),自動(dòng)繪圖代替了人工繪圖,自動(dòng)檢索代替了手冊(cè)查閱,快速分析代替了手工計(jì)算,使模具設(shè)計(jì)師能從繁瑣的繪圖和計(jì)算中解放出來,集中精力從事諸如方案構(gòu)思和結(jié)構(gòu)優(yōu)化等創(chuàng)造性的工作。 　　當(dāng)今的概念設(shè)計(jì)已不僅僅是停留在對(duì)外觀和結(jié)構(gòu)的設(shè)計(jì)上,它已經(jīng)擴(kuò)展到對(duì)模具結(jié)構(gòu)分析的領(lǐng)域。通過這些分析,可以檢驗(yàn)前面的概念性結(jié)構(gòu)設(shè)計(jì)是否合理,分析出結(jié)構(gòu)不合理的原因和部位,然后再在CAD軟件中進(jìn)行相應(yīng)的修改。 　　當(dāng)今CAD技術(shù)的發(fā)展使得概念設(shè)計(jì)思想體現(xiàn)在相應(yīng)的模塊中。目前,世界上大型的CAD/CAE軟件系統(tǒng),如Pro/ENGINEER、UG、Solidworke、Alias等,都提供了有關(guān)產(chǎn)品早期設(shè)計(jì)的系統(tǒng)模塊,我們稱之為工業(yè)設(shè)計(jì)模塊或概念設(shè)計(jì)模塊。此模塊工具包括概念設(shè)計(jì)的二維非參數(shù)化的裝配布局編輯器。 　　 　　3現(xiàn)代模具制造的CAD/CAE/CAM技術(shù)應(yīng)用 　　 　　現(xiàn)代經(jīng)濟(jì)的飛速發(fā)展,推動(dòng)了我國模具工業(yè)的前進(jìn)
