徐华善：基于Pro/E的零件设计与制造I摘要Pro/E是美国PTC公司著名的CAD/CAM3D设计系统自1998年问世以来，已经逐渐成为当今世界最普及的CAD/CAM3D系统的标准软件广泛应用与机械、模具、工业设计、汽车、电子、航空航天、家电等各行业。Pro/E的功能非常强大，使用它能够进行诸如零件设计、产品组合、模具开发、NC（NumberControl数控）加工、钣金件设计、铸造件设计、造型设计、逆向工程、自动测量、运动仿真、应力分析、以及产品数据库管理等工作。但是Pro/E结构庞大，模块众多，所以学起来很难。本文通过对轴杆导块的设计和对外型轮廓进行粗加工程序设置，首先利用Pro/E进行整体设计，再通过参照图对所设计的零件进行精密的尺寸限制和适当的修改。而在制造方面，利用铣削窗口规划加工范围；以体积块NC序列从加工坯料开始进行粗加工。通过PTC/NC模块的使用，了解和掌握了步长深度，跨度，切割角及扫描类型等制造参数对刀具轨迹的影响，最终完成了轴杆导块的设计和制造。通过这次的设计使我对Pro/E也有了很深的了解。Pro/Engineering，CAD/CAM，轴杆导块，零件设计，数控加工钟山职业技术学院毕业论文II目录摘要····························································································································I第一章绪论················································································································11.1CAD/CAM技术的形成与发展·························································································11.2PRO/E软件的特点及主要功能························································································11.3轴杆导块的几何特征与CAD/CAM················································································11.4课题内容及实施步骤·······································································································1第二章基于Pro/E的零件CAD建模·····································································22.1整体外形设计··················································································································22.2切割体的生成··················································································································42.3挖孔·································································································································52.4开槽与倒角······················································································································62.5小结··························································································································
