Abstract
The numerical control technology is the modernized manufacturing industry core. Its development beginning to US, has until now passed through half excessively many centuries development courses. The present numerical control technology to the high accuracy, the high intellectualization, the high velocity direction is developing. Enters the world along with our country thorough, our country gradually is becoming the world manufacture base, the enterprise to the numerical control technology talented person''s demand quantity more and more in a big way, more and more is also high to the numerical control technical personnel''s skill request. Will be precisely caters to this social development tendency, this article carries on the analysis to the numerical control processing technology craft, mainly will introduce the numerical control processing technology the practical application.
Key word: Numerical control processing technology;analysis; application
