The graduation design is based on the Pro/e computer modeling design , one of the main part is software Pro/e application. Focus on modeling process of papers.

Due to the papers written order is: according to the actual work, from the 3d modeling software parting, again carries on the nc machining of related work. The first chapter is introduced and the Pro/E, through its characteristics, we can understand the Pro/E in the development of social production industry, and their importance from a new perspective of production needs and future development direction, let us keep production steps, also remind us to do old old, Chapter 2 is the basic knowledge of computer and the use of some brief introduction, The third chapter is based on the PRO/E computer modeling design, highlight the thesis processing product modeling process of software and application software of parting. Through this chapter can understand the PRO/E, understand the application of PRO/E modeling and manufacturing partial function,

This design from reality and systematically introduced based on PRO/E, function module, the concave-convex application instructions and CNC processing method and relevant operation. Through the detailed process and lots of pictures, teachers and fellow leaders clearly understand PRO/E product design functions.

Because of my limited, design of existing shortcomings and errors unavoidably, your teacher correct.
