密级: 学号:111202020021 本科生毕业论文（设计） 基于UG的QQ企鹅产品造型设计与数控加工 学 院：__________________________ 专 业：__________________________ 班 级：__________________________ 学生姓名：__________________________ 指导老师：__________________________ 完成日期：__________________________  摘 要 在计算机逐步发展的时代，UG造型设计已经越来越多的被应用到诸多领域。尤其是在数控加工方面显得尤为突出。随着社会经济的发展，人们对产品外观造型越来越看重。人们更是期待看到一些形状复杂，样子精美的产品。如果将UG与数控机床的联合起来，它就刚好能够完成对这些类产品的设计和数控加工。目前。玩具制造业正蓬勃发展，而此次毕业论文将要设计的更是一个非常漂亮和精致的QQ企鹅挂件，相信会非常迎合社会潮流。 本次毕业设计，介绍了QQ企鹅产品从毛坯到成品的大致过程。通过对零件图的分析，选择毛坯材料和相关加工设备，确定定位基准和装夹方案，分析了刀具的选择原则、切削用量的选择原则和加工工艺方案。然后编制了工序卡片、工艺卡片和刀具卡片。在设计中先运用UGNX6.0绘图软件绘制出QQ企鹅，然后运用后置处理功能自动生成数控程序，然后设置数控仿真的相关参数，并模拟QQ企鹅的虚拟加工过程。最后用数控机床做出QQ企鹅。 关键词：造型设计；数控加工；加工工艺；数控程序 Abstract In the progressive development of computer age, and UG design is increasingly being applied to many other areas. Especially in the CNC machining is particularly prominent. Along with the socio-economic development, people on product appearance and value. People are looking forward to seeing some complex shapes, attractive products. If UG join forces with CNC machines, it will just be able to complete the design and CNC machining of these products. At present. Toy industry is booming, and the graduation thesis will be designing is a very beautiful and refined the QQ Penguin pendants, I believe it will cater to social trends. The graduation design, introducing the QQ Penguin from rough to finished products. By analyzing the parts diagram, select blank materials and related processing equipment to determine positioning and clamping, analyzes the tool selection principles, selection cutting and machining process. Cards, cards and then developed a process tool card. Design drawing UGNX6.0 drawing software QQ Penguin first and then applying postprocessing features automatic generation of NC programs, and then set the parameters of NC simulation, QQ Penguin and simulatio
