以一个复杂曲面零件模型为例，论述了UG CAD/CAM 系统在数控加工中的应用过程：利用UG 的建模模块对

其进行曲面造型设计，并根据该零件结构特点进行工艺分析，使用UG 的CAM 加工模块设置加工参数实现自动编程，

由程序后处理自动生成NC 代码，最后将NC 代码导入数控机床加工出实体零件，从而达到缩短编程时间，提高工作效

率和编程质量的目的，有效地保证了零件的加工精度-A model of a complex surface parts, for example, discusses the UG CAD/CAM system application process in NC machining: UG modeling module using its curved design, and process analysis based on the structural characteristics of the components, the use of UG The CAM processing module for automatic programming process parameters set by the program automatically generate NC code processing, and finally the NC code into CNC machining of solid parts, so as to reduce programming time, improve work efficiency and quality of programming purposes, effectively ensure precision machining of parts
