【正文】 industry development of numerical control of our country The technology of numerical control of our country started in 1958, the development course in the past 50 years can roughly be divided into 3 stages: The first stage is from 1958 to 1979, . closed developing stage. In this stages, technology of foreign countries blockade and basic restriction of terms of our country, the development of the technology of numerical control is paratively slow. During w “ Sixth FiveYear Plan Period ” the Seventh FiveYear Plan Period of the country in second stage and earlier stage in the Eighth FiveYear Plan Period , introduce technology , digest and assimilate, the stage of establishing the system of production domesticization arisesing tentatively. At this stage , because of reform and openingup and national attention , and study the improvement of the development environment and international environment, research , development and all making considerable progress in production domesticization of the products of the technology of numerical control of our country. The third stage is that on the later stage in the Eighth FiveYear Plan Period of the country and during the Ninth FiveYear Plan Period , implement the research of industrialization , enter market petition stage. At this stage, made substantive progress in industrialization of the domestic numerical control equipment of our country. In “ the Ninth FiveYear Plan ” latter stage, domestic numerical control domestic market share of lathe reach 50% , mix domestic numerical control system (popular ) to up to 10%. Review the development course in the past 50 years of technology of numerical control of our country, especially pass the brainstorm of 4 FiveYear Plans, all in all has made following achievements. a. Have establish the foundation of the technical development of numerical control, has basically mastered the technology of modern numerical control. Our country know from numerical control system , servo urge , numerical control host puter , special plane and their basic of fittings basically already now, among them most technology have already possessed the foundation that is mercialized and developed , some technology has already, industrialization mercialized. a. Have formed the industrial base of numerical control tentatively. In tackling key problems the foundation that the achievement and some technology mercialize , set up the systematic factories of numerical control with production capacity of batch such as numerical control of Central China , spaceflight numerical control etc.. Electrical machinery plant of Lanzhou, a batch of servo systems and first machine tool plant , first machine tool plant of Jinan of servo electrical machinery factory and Beijing ,etc. several numerical control host puter factories such as the numerical control in Central China. These factories have basically formed the numerical control industrial base of our country. b. Have set up research of a numerical control, development , managerial talent39。s basic team . Though has made considerable progress in research and development and industrialization of the technology of numerical control, but we will realize soberly, the research and development of the technology of advanced numerical control of our country, there is greater disparity between current situation and current demand of our country of engineering level especially in industrialization. Though very fast from longitudinal development to watch our country, horizontal until (contrast with foreign countries ) , the engineering level has disparity, there is disparity too in development speed in some aspects, . the disparity of engineering level between some highgrade , precision and advanced numerical control equipment has the tendency to expand . Watch from world, estimate roughly as follows about the numerical control engineering level of our country and industrialization level. w a. On the engineering level, in probably backward 10 1 years with the advanced level in foreign countries, it is bigger in highquality precision and sophisticated technology. b. At the industrialization level, the market share is low, the variety coverage rate is low, have not formed the largescale production yet。 Function part specialized level of production and form a plete set ability to be lower。 Appearance quality is relatively poor。 Dependability is not high, the mercialized intensity is insufficient。 Not setting up one39。s own brand effect yet in domestic numerical control system, users have insufficient confidence. c. At the ability of sustainable development, to petition numerical control research and development of technology, engineered ability weaker。 Numerical control technological application expand efforts to be better。 The research , formulation that relevant standards are normal lags behind. It is analyzed that the main reason for having disparity described above has the following several respect. a. Realize the respect. Know to domestic numerical control industry process arduousness , plexity and longterm characteristic insufficiently。 One that is to market unstandard, foreign blockade add strangle , system ,etc. underestimate while being difficult。 It is not enough to analyze to technological application level and ability of numerical control of our country. b. System. Pay close attention to numerical control industrialization many in the issue , consider numerical control industrialization little in the issue synthetically in terms of the systematic one , industry chain in terms of technology。 Set up intact related system , plete training , service work ,etc. of high quality support the system. c. Mechanism. The bad mechanism causes the brain drain , restraining technology and technological route from innovating again , product
