"UG软件三维CAD设计与CAM自动编程研究"

本文主要研究了基于UG软件的三维CAD设计和CAM自动编程的过程。首先利用UG软件的CAD模块对待加工的零件进行实体建模，然后根据零件的三维实体模型进行实体造型，并探讨了零件三维实体建模的方法、建模过程和处理技巧。在对零件形状结构进行分析的基础上，制定了它们的加工工艺，分析了数控自动编程的方法和特点，利用UG的CAM模块完成了粗加工、半精和精加工的NC编程，并对生成的操作进行了切削仿真加工，以确保操作的正确性。最后对生成的操作进行了后置处理，生成了数控机床可以识别的NC代码程序。 关键词：UG，CAD，CAM，自动编程 Abstract: This article introduces the process of how to design the part using the function of CAD and CAM basing on the UG software. First of all, utilize UG software CAD module to adjust the spare parts which will be processed and carried out solid modeling according to the three-dimensional solid model of the part. In addition, it discusses the methods, process, and techniques of three-dimensional solid modeling of the part. Based on the analysis of the shape and structure of the part, the processing technology is formulated, and the method and characteristics of CNC automatic programming are analyzed. With the use of the CAM module of UG, rough machining, semi-precision machining, and precision machining NC programming are completed, and the generated operations are subjected to cutting simulation processing to check the correctness. Finally, post-processing is performed on the generated operations to generate NC code programs that can be recognized by CNC machine tools.
