fanuc数控（FANUC数控） The development of CNC technology in China started in 1950s, through the 65 during the introduction of numerical control technology, 75 organization during the digestion and absorption of science and technology research, Chinas numerical control technology and industry has made considerable achievements. Especially in recent years, Chinas CNC industry has developed rapidly, and the average annual growth rate of domestic CNC machine tools output and consumption in 1998~2004 years was 39.3% and 34.9% respectively. Nevertheless, the development momentum of the imported machine is still strong, from the beginning of 2002, China for three consecutive years to become the worlds largest machine tool consumption, machine tool imports superpower, 2004 China machine consumption of up to $9 billion 460 million, research and development of manufacturing enterprises in the domestic CNC machine tool of high-grade and large-scale CNC machine tools as the gap with foreign countries becomes more obvious. More than 70% of these devices and the vast majority of features are dependent on imports. It can be seen that the domestic CNC machine tools especially in high-end CNC machine tools is still a lack of market competitiveness, the main reason is that the research on the deep development of domestic CNC machine tools is not enough, the manufacturing level is still backward, service consciousness and the lack of capacity, numerical control, system production application ineffective and NC talents lack. We should see clearly the situation, fully understand the shortcomings of the domestic CNC machine tools, and strive to develop advanced technology, increase technological innovation and training services to shorten the gap with the developed countries. Numerical control machine tools digital control machine tools are digital code form of information (program instructions), control tools according to the given work procedures, speed and trajectory of automatic processing
