Flexible manufacturing technology are of various shapes of machining object to realize flexible manufacturing stylized the sum total of various technologies. The flexible manufacturing technology is a technology intensive technology group, who focuses on the flexible, suitable for many varieties, small batch, including single product, processing technology belong to a flexible manufacturing technology.

Flexible can be expressed as two aspects. The first is the ability of system to adapt to changes in the external environment on the one hand, the degree of system satisfies the requirement of new products are available to measure; The second aspect is the ability to adapt to changes in internal system, available in interference (such as machine malfunction of automation product line is mainly a single variety of mass production. Its advantage is that productivity is high, because the device is fixed, so the equipment utilization rate is also high, single product cost is low. But the price is quite expensive, and can only process one or a few similar parts. If you want to obtain other varieties of products, it must be to adjustment of the structure, configuration elements from the system, its workload and fund input and construct a new production line often. Rigid mass manufacturing automation product line is only for a few varieties of products, it is difficult to deal with many kinds of medium and small batch production.

Along with the social progress and improvement of living standards, more market demand characteristic, conform to the requirements of the customers'''''''''''''''' personal styles and functions of different products. The fierce market competition forces the traditional mass production mode change, requirements for the parts of the traditional production process is improved. Traditional manufacturing system can not meet the market demand for more varieties of small batch products, which makes the system flexible to system existence more and more important. With the mass production time is gradually replaced by the dynamic production to adapt to the market, a survival ability and competition ability of manufacturing automation system depends largely on whether it can in a very short development cycle, to produce different varieties with lower cost and higher quality products. Flexible has been occupies an important position
