端面凸轮冷精锻模得三维设计及凸模的NC加工设计说明书.docVIP

端面凸轮冷精锻模的三维建模及凸模NC加工 ee (ee) 指导老师：ee [摘要]在传统的装配过程中,当一个零部件与另一个零部件装配失败后,只能返回装配结果,重新设计,重新生成样品,重新用真实装配来检验。这种装配关系的滞后检验,不但带来成本的巨大浪费,而且完全不符合快速反应市场的需要。随着计算机软件硬件技术的发展,在机械制造领域中,零部件如何装配、加工、各零部件是否发生干涉等都能在虚拟装配环境中实现。同时,借助虚拟装配技术,能在产品设计阶段就能了解设计结果的装配性。这种虚拟装配技术对小批量生产方式具有开发周期短、设计质量高,开发成本低等特点。以端面凸轮冷精锻模为例，基于CATIA环境下进行三维建模和零部件的虚拟装配并对凸模进行NC数控加工模拟。 [关键词]虚拟装配 三维建模 CATIA 数控加工  End CAM precision cold forging die of 3 d modeling and convex mold NC machining ee (ee).Tutor: ee [Abstract] In traditional assembly process, when a parts with another parts assembly failed, only to return to assembly as a result, the redesign, regenerate the sample, with real assembly to test again.The lag of inspection, the assembly relationships, not only the huge waste of cost, and completely do not conform to the rapid response to market needs.With the development of computer software, hardware technology, in the field of mechanical manufacturing, parts how to intervene with assembly, processing, all parts are in, etc. Can be implemented in the virtual assembly environment.At the same time, with the aid of virtual assembly technology, can in the product design phase can understand the design result of assembling.This kind of virtual assembly technology of small batch production mode has short development cycle, design, high quality, low cost of development.To end CAM precision cold forging die as an example, based on CATIA environment for 3 d modeling and virtual assembly of parts and NC NC machining simulation was carried out on the punch.
