Abstract

The abstract numerical control technology is the development emerging high-tech industry and the state-of-art industry use technology and the most basic equipment. Now the various countries mechanical manufacturing industry widespread application numerical control technology, sharpens the manufacturing capacity and the level, the enhancement to the dynamic changeable market adaptive and the centralism competitive ability, vigorously develops take the numerical control technology as the core advanced manufacture technology, has become world each developed country to add the book fast economy development, the enhancement comprehensive national strength and the

national status important way.

Now, the numerical control engine bed capacity and the level have become weighs a national industrialization the important symbol, therefore our country government positively takes each kind of effective action vigorously to develop our country numerical control industry, the development numerical control technology took the promotion mechanical industry heavy center is heavy.

This graduation thesis first introduced studied the significance and the background and to the numerical control technology development tendency and this article has carried on the comprehensive elaboration to the topic content and the request; Then elaborated the complex components processing craft, not only introduced the numerical control turning processing related content also included the detail drawing analysis, the work piece localization, the working procedure determination, the cutting tool design and the choice as well as the craft route system grades; Then is in carries on the craft analysis to this topic components, the compilation processing procedure, and carries on the simulation to the procedure, the numerical control processing and to processes the result the examination; Finally was this graduation project conclusion are partial, induces and summarizes this graduation project content and the process.

Key words: Numerical control technology、turning processing 、processing craft 。
