Abstract

Entering into the 21st century, mold has been gradually formed an industry, the development of abrasive processing is a growing fire.
In this paper, first expounded on the development of mold and looking forward to the future status of mold. Then mold the various mechanical process to conduct a comprehensive analysis and study. Through this mold design graduate, I really know is the role of the abrasive, in the future prospects.
Key words: Die Process Technology of
