Abstract
NC technology and equipment manufacturing industry is an important foundation for modernization. This is the basis of a strong direct impact on the country's economic development and comprehensive national strength, and bearing on a country's strategic position. TIn China, the CNC technology and equipment development has also been a high degree of attention in recent years has made considerable progress. Particularly in the area of general computer numerical control, PC-based platform for domestic CNC systems, has been at the forefront of the world. China, however, is in NC technology research and development industries also have many problems, particularly in the ability of technological innovation and commercialization process, and other aspects of market share is even more conspicuous. In the arrival of the new century, how to effectively solve these problems, China's NC areas along the path of sustainable development, from the overall comprehensive entered the ranks of the advanced world, we in the international competition in a pivotal position, will be NC research and development departments and manufacturers facing the important task. NC system is the core of all types of CNC equipment, first through the development of scientific and technological innovation with Chinese characteristics, the new NC system, will be to promote the industrialization process of NC effective technical means. Practice has proven that the past 10 years we are moving in the PC NC road is completely correct. PC machines (including industrial PC) output is big, cheap, technological progress, and quickly improve performance, and high reliability (MTBF host PC industry has reached 30 years). Therefore, as a CNC system with the hardware and software platform can greatly improve the cost-NC system, but also make full use of existing generic computer hardware and software resources and sharing the latest achievements in the field of computers, such as large memory capacity, high - color display, multimedia information exchange, networking and communications. In addition, as the common computer platform can also access NC rapid technological progress, when PC-upgrading, NC system can also be corresponding upgrades to maintain long-term technical advantages in the competition to be invincible. This high-performance, high reliability, low cost, the new NC system is highly competitive, is expected to open up a new situation in China to contribute to NC.
