Throughout nearly 50 years of China's CNC technology development process, especially through four five-year plan of research, the overall look achieved the following results。
a。 laid the foundation for the development of numerical control technology, basic grasp of modern CNC technology。 Our country is now basically understood from the NC system, servo drives, CNC host, plane and its component parts to basic technology, most of which technology has been available for commercial development foundation, part of the technology has been the commercialization and industrialization 。
b。 initially formed a CNC industrial base。 In the commercialization of research results and some of the techniques, based on the established, such as central NC , aerospace CNC CNC system has the ability to mass production plant。 Lanzhou Electric Factory, a group of Huazhong CNC servo systems and servo motor manufacturing plant and the Beijing No。 1 Machine Tool Plant, Jinan first machine tool factory hosts a number of CNC manufacturing facility。 The plant basically formed the NC industrial base of China。
c。 establishment of a numerical control research, development, management personnel and the basic team。
Although the numerical control technology research and development and industrialization has made great progress, but we must also soberly aware that China's high-end numerical control technology research and development, especially in the industrialization of the technological level of the status quo with China's practical needs there is a large gap。 Although longitudinal look at China's growing so rapidly, but the horizontal ratio (compared with foreign countries) not only technical level there are gaps in some areas there is disparity between the pace of development that a number of sophisticated CNC equipment, to expand the gap between the technological level of the trend。 From an international point of view, China's numerical control technology and industrialization level is estimated as follows。
a。 technical level, and behind the advanced level of about 10 to 15 years, and even more sophisticated technology 。
b。 the level of industrialization, the market share of low-species coverage of small-scale production has not yet formed; functional components and the complete set of professional level of production capacity to low; appearance quality is relatively poor; reliability is not high, lack of commercialization ; domestic CNC system has not yet set up their own brand , the user's lack of confidence。
c。 capacity for sustainable development, the right pre-competitive research and development of numerical control technology, engineering capabilities weak; CNC technology applications to expand the intensity is not strong; the relevant standard specification research , development lagged 。
Analysis of the main reasons for this gap exists in the following areas。
a。 awareness。 Arduous process of home-made CNC industry, complexity, and inadequate understanding of the characteristics of long-term nature; on the market are not standardized, foreign stifling blockade increases, institutional difficulties such as underestimation; on China's CNC technology level and capability analysis is not enough。
b。 system aspects。 From a technical point of view concerns the issue when the NC industry more, from the systematic and comprehensive consideration the perspective of industry chain of the issue when the NC industry less; failed to establish a complete high-quality supporting system, comprehensive training, services, network support system 。 The brain drain caused by bad system, but also restricted the line of innovation in technology and technology, product innovation , and constrained the effective implementation of the planning, often planning vision, implementation difficulties。 数控技术和设备的发展趋势英文文献和中文翻译(5):http://www.youerw.com/fanyi/lunwen_97816.html
