Numerical control technology is the basis of modern manufacturing technology. The wide application of NC technology makes the CNC machinery replace the ordinary machinery, which result in the fundamentally changes in global manufacturing industry. The level of CNC technology, possession, and penetration has become one of the important symbols to measure a country’s comprehensive strength and the level of industrial modernization.
The CNC machining has the following advantages:

1. A substantial reduction in number of tools, without complex tooling for parts with complex shape. If you want to change the shape and size of the parts, only need to modify the processing procedures of the parts to adapt to the development and modification of the new product.
2. The production efficiency is relatively high under the condition of many varieties and small quantities, which can reduce the time for production preparation, the adjustment of the machine  and process inspection. By using the optimal cutting quantity to reduce the cutting time.
3. Stable machining quality and high machining precision.
4. It can process the complex curve surface which cannot be processed by conventional machining method. It even can process some position which cannot be observed.

The main disadvantages of CNC machining is that the cost of the CNC machine tool equipment is expensive, which requires repair personnel has high level of techniche.
