Abstract
With the development of numerical control technology, numerical control technology for the traditional manufacturing industry has brought the revolutionary change, manufacturing has become the symbol of industrialization,and with the development of technology and application domain expansion. It is important to some of the development of industry that plays a more and more important role. With the development of science and technology, numerical control technology is in the development of updates. Now, numerical control technology are called computer numerical control technology. The application of CAD/CAM is a practical technique, like UG, PRO/E, Master CAM, CAXA manufacturing engineers, etc.
Numerical control technology is highly technical work, especially in the mold domain. Practitioners requires high machining technology knowledge, CNC programming knowledge and skills.This text based on the analysis of nc craft and machining, comprehensive knowledge of professional knowledge, comprehensive consideration the influence factors of milling process, design the craft and editing program, complete requirements.
Keywords: milling, CAD/CAM, UG, nc machining
