模具的发展趋势-------外文翻译.doc

1.mold CAD / CAE / CAM being integrated, three-dimensional, intelligent and network direction
(1) mold software features integrated
Die software features of integrated software modules required relatively complete, while the function module using the same data model, in order to achieve Syndicated news management and sharing of information to support the mold design, manufacture, assembly, inspection, testing and production management of the entire process to achieve optimal benefits. Series such as the UK Delcam's software will include a surface / solid geometric modeling, engineering drawing complex geometry, advanced rendering industrial design, plastic mold design expert system, complex physical CAM, artistic design and sculpture automatic programming system, reverse engineering and complex systems physical line measurement systems.
(2) mold design, analysis and manufacture of three-dimensional
Two-dimensional mold of traditional structural design can no longer meet modern technical requirements of production and integration. Mold design, analysis, manufacturing three-dimensional technology, paperless software required to mold a new generation of three-dimensional, intuitive sense to design the mold, using three-dimensional digital model can be easily used in the product structure of CAE analysis, tooling manufacturability eva luation and CNC machining, forming process simulation and information management and sharing. Such as Pro / ENGINEER, UG and CATIA software such as with parametric, feature-based, all relevant characteristics, so that mold concurrent engineering possible. In addition, Cimatran company Moldexpert, Delcam's Ps-mold and Hitachi Shipbuilding of Space-E/mold are professional injection mold 3D design software, interactive 3D cavity, core design, mold base design configuration and typical structure . Australian company Moldflow realistic three-dimensional flow simulation software MoldflowAdvisers been widely praised by users and applications. China Huazhong University of Science have developed similar software HSC3D4.5F and Zhengzhou University, Z-mold software. For manufacturing, knowledge-based intelligent software function is a measure of die important sign of advanced and practical one. Such as injection molding experts Cimatron's software can automatically generate parting direction based parting line and parting surface, generate products corresponding to the core and cavity, implementation of all relevant parts mold, and for automatically generated BOM Form NC drilling process, and can intelligently process parameter setting, calibration and other processing results.




1 模具CAD/CAE/CAM正向集成化、三维化、智能化网络化方向发展
1.1模具软件功能集成化
模具软件功能的集成化要求软件的功能模块比较齐全，同时各功能模块采用同一数据模型，以实现信息的综合管理与共享，从而支持模具设计、制造、装配、检验、测试及生产管理的全过程，达到实现最佳效益的目的。如英国Delcam公司的系列化软件就包括了曲面/实体几何造型、复杂形体工程制图、工业设计高级渲染、塑料模设计专家系统、复杂形体CAM、艺术造型及雕刻自动编程系统、逆向工程系统及复杂形体在线测量系统等。集成化程度较高的软件还包括：Pro/ENGINEER、UG和CATIA等。
1.2模具设计、分析及制造的三维化
传统的二维模具结构设计已越来越不适应现代化生产和集成化技术要求。模具设计、分析、制造的三维化、无纸化要求新一代模具软件以立体的、直观的感觉来设计模具，所采用的三维数字化模型能方便地用于产品结构的CAE分析、模具可制造性评价和数控加工、成形过程模拟及信息的管理与共享。如Pro/ENGINEER、UG和CATIA等软件具备参数化、基于特征、全相关等特点，从而使模具并行工程成为可能。另外，Cimatran公司的Moldexpert，Delcam公司的Ps-mold及日立造船的Space-E/mold均是3D专业注塑模设计软件，可进行交互式3D型腔、型芯设计、模架配置及典型结构设计。澳大利亚Moldflow公司的三维真实感流动模拟软件MoldflowAdvisers已经受到用户广泛的好评和应用。国内有华中理工大学研制的同类软件HSC3D4.5F及郑州工业大学的Z-mold软件。面向制造、基于知识的智能化功能是衡量模具软件先进性和实用性的重要标志之一。如Cimatron公司的注塑模专家软件能根据脱模方向自动产生分型线和分型面，生成与制品相对应的型芯和型腔，实现模架零件的全相关，自动产生材料明细表和供NC加工的钻孔表格，并能进行智能化加工参数设定、加工结果校验等。
