毕业设计说明书 基于UG的电话机听筒造型及型腔模数控程序设计 班 级： 学号： 姓 名： 学 院： 专 业： 指导教师： 2013年 6 月 基于UG的电话机听筒造型及型腔模数控程序设计 摘 要 我的设计是应用基于Windows平台的三维建模软件生成零件的外形和模具等外形,然后再生成加工轨迹去加工。这是生成并制造模具的流程过程。在设计中,我先建立零件的模型并生成加工零件的模具外形。模具的凸模和凹模都是在软件中生成的。而且达到了它们之间需要的配合关系。利用模具的模型生成加工轨迹和NC代码。这样就可以应用NC代码在数控机床上面加工了。在设计中,我采用主流的设计软件Unigraphics来设计零件、模具的外形,并生成加工轨迹和NC代码。 毕业设计的内容就是加工一个简单的型腔模具的流程。在实际生产中的过程与这个流程类似。 CAD/CAM软件在生产中的应用是十分广泛的,从建模到生成加工轨迹都是在一个软件中实现的。 关键词：UG，CAD，三维建模，代码，模具，NC代码  UG-based telephone handset modeling and NC programming cavity mold Abstract My design is the application based on Windows platform to generate a three-dimensional modeling software and other parts of the shape and mold shape, and then generate the toolpath to processing. This is the process of generating and manufacturing mold process. In the design, I first create a model and generate parts machined parts of the mold shape. The mold punch and die are generated in software. But also to the need with the relationship between them. The model generation using a mold machining path and NC code. This can be applied to NC code above in CNC machined. In the design, I used the mainstream Unigraphics design software to design parts, mold shape, and generate toolpath and NC code. Graduation project is a simple cavity mold machining process. In the actual production process similar to this process. CAD / CAM software in a production application is very broad, from modeling to generate toolpath are implemented in a software.
