Advanced production technology raises new requirement to our country manufacturing industry

Since reforming and opening, as the rapid development of our country manufacturing industry, production technology level also enters world front row. Although, at present the ability of innovation of science and technology of our country manufacturing industry had different rate rise, but average level is lower, basically be creation of advance gradually sex and product innovation are given priority to, revolutionary innovation and craft innovation are very few still, manufacturing product breed is little, additional cost and technical content are low. On the other hand, as the development of social demand individuation, diversification, small lot of edge of scale of production -- large quantities of quantities -- much breed goes the way of batch develops, and of the hi-tech that is a delegate with the computer and modernization management technique introduce, permeate and melt, changing the appearance of traditional production technique and intention ceaselessly. Accordingly, be necessary to examine our country afresh advanced production technology (AMT) the opportunity that faces in new period and challenge. The expands our country of course of development to make a technology development of 1 production technology can divide for 3 phase: 1.

1 manual stage of production this one phase, production instrument and level are lower, for individual produce with small mill, reflected body brain tie, design and production an organic whole, technical level depends on experience, it is sheet more, small lot produces kind, basically got used to the demand that the mankind expands at that time. 1.

Stage of production of 2 big industry falls in the drive of market economy, market demand had very big rise, in addition, of level of science and technology rise and of foreign technology introduce make production method and level had very big rise, formed big industry to produce kind. Strict division of labor and manufacturing schedule formed automation water product line, the big batch production of onefold breed is the characteristic with this the largest stage, but also brought at the same time design and make break up, the situation with body detached brain. The development of the ceaseless promotion of the ceaseless development as our country economy, people to corporeal culture demand and change quickly of whole world science and technology, the speed that the product changes is accelerated ceaselessly, answer much breed sheet quickly the market demand of pre production product became an outstanding contradiction. 1.

Stage of production of industry of 3 virtual realities looks from the development process of production technology and manufacturing industry, our country is in 21 centuries will be long-term in the concept that technology of an IT, computer, network technology blends in AMT, use large-scaly compositive make, collateral project, computer is emulated, fictitious make, the act such as dynamic alliance and electronic business affairs, design and production height union, with the method of virtual reality, it is the design phase of the product and production phase be in harmony an organic whole, can discover the problem in making in the design. In addition, another characteristic of this one phase can collect the production resource of the whole world to undertake the collaboration of whole world limits is produced namely, shorten appear on the market time, improve product quality. 2AMT raises new requirement to our country manufacturing industry 2.

1 digitlization is made -- the core digitlization technology of AMT and the confluence of production technology form digitlization to make a technology, its are main connotation is: (1) with QFD/CADD/DFX/VM/RP/CAM/CAE and shape and treatment craft is emulated wait for the upriver backbone technology that gives priority to body group. (2) make by NC/NGC/CNC/DNC/FMC/PFMC/FMS/PFMS/Web-based, be made without blueprint and the downstream number of the composition such as system of robot, content shedding controls a technology group. (3) with IGES/STEP/MRPII/ERP/MIS/PDM/TDM, the project database and Internet production information that gives priority to a problem supports a technology group. 2.

2 nicety are changed -- the precision demand that nicety changes the key that AMT develops to point to pair of products, spare parts on one hand is higher and higher; The treatment precision demand that points to pair of products, spare parts on the other hand is higher and higher. Treatment precision and its development can be divided for accurate treatment, subtle treatment, Namijia labour is waited a moment. At the beginning of 20 centuries, the error of superprecision is 10 μ M, achieve up to now 0.

00l μ M, namely Lnm. The production of microelectronics chip calls somewhat " 3 exceed " : (1) exceed clean, diameter of grain of job shops dust is less than L μ M, grain counts ＜ 0.

A ／ 0.

028m3; (2) exceed pure, chip data is harmful foreign matter, its content is less than billion 1/0; (3) exceed essence of life, treatment precision amounts to accept rice class. Apparent, without advanced production technology, equip without advanced electron technology. 2.

3 extremes are changed -- the focal extreme that AMT develops is changed is to point to what make in extreme condition come off work or the product that has extreme demand, also be to show the production technology of this kind of product has thereby " extremely " requirement. Corroding those who wait for the job below the condition high temperature, high pressure, tall wet, strong magnetic field, by force, or have the demand such as tall hardness, big flexibility, or extremely great on geometrical body, dinky, thick, paper-thin, grotesque. The science and technology of a forward position that pays close attention to like height of industrial developed country " system of personal computer cable (MEMS) " , its apply the molecular memory in information field, chip to machine equipment; Operating system of the clone technology in life domain, gene; The technology of accurate control and guide in martial weapon, hit a technology accurately; The miniature plane in aerospace domain, miniature satellite, "Accept rice " satellite (0.

1kg less than) ; And medical miniature robot is waited a moment. 2.

4 automation -- the condition that AMT develops is mixed from automata, self-adjusting, automatic compensation differentiate automatically development reviews to self-study, organize oneself, be safeguarded oneself and wait from repair, the connotation of automata and level are to be not former times comparing today. Controlling theory (the control theory of the theory of Agent system and method, control theory that is based on a network, complex system) , control a technology (intelligence is changed detect, multimedia information detects wait) , system (network control system, complex system) , control component (have, automation technology is the premise condition that AMT develops. 2.

5 compositive change -- of the methodological AMT that AMT develops compositive change include the following fields: (1) of modern technology compositive (for example technology of unifinication of machine, report, fluid, gas) . Of modern technology compositive often involve detect pass feeling technology, information processing technology, automata technology, servo drive technology, accurate mechanical technology, system overall technology, hydraulic pressure / the across of the much discipline such as baric drive. (2) of processing technique compositive (for example non-traditional machining technology and its equipment) . (3) the enterprise is compositive (run paralell for example project, nimble make, seed profit production, CIMS) . Those who include to produce information, function, course is compositive; Of the course of cycle of compositive, whole life that includes to produce a course compositive; What also include enterprise interior is compositive, the enterprise is external compositive. 2.

6 network -- the develops road to make a technology network of AMT is advanced the only way that production technology develops. It basically is reflected in two respects, it is to use a network to be in products plan, in making circuit of as whole as activity and even the enterprise such as manufacturing management business enjoy concerned resource adequately, assemble quickly namely organic conformity and efficient use about production resource; 2 be production process and organization is dispersive change, network, make the enterprise concentrates power on his most competitive core business. 2.

7 intelligence are changed -- the expands foreground intelligence to change production pattern base of AMT is intelligent production system, what intelligence makes systematic since intelligence and technology is compositive and formation applied environment, also be the carrier of intelligent production mode. Compare with traditional production photograph, intelligence makes a system have the following characteristic: (1) man-machine unifinication; (2) autonomic ability; (3) be organized oneself and exceed flexible; (4) study ability and ego maintain ability; (5) in future, have the capacity of kind of more advanced person thinking. 2.

8 green -- in making a process what AMT develops necessarily, the TQCS besides integrated consideration product (Time, quality, cost, service) attribute, the E that pays attention to a product even (Environment) attribute, namely the green chroma that the product uses, after the portion is promulgated formally and was being carried out in January 1996 in ISO14000 of standard of international environmental protection, this will more and more become a when measure product performance main factor. The product of manufacturing industry begins from conception, to design phase, production phase, sale phase, use with maintenance phase, until reclaim level, reproducing each phase, must involve environmental protection adequately, make should move toward necessarily " green " make. The emerge in large numbers of the new-style production technology such as the development of technology of imitate of the application of the development of figuration production technology to clean figuration direction, treatment doing type, craft, RPM/LOM/FDM is green the main show that production technology uses. The 3 bottleneck problems that restrict development of our country manufacturing industry 3.

1 serial production corrupt practice is current, the enterprise makes the systematic application software that lack can handle each other, the exchange that devises data is restricted; Standard of technical data exchange also is mixed because of craft individuation compositive those who change is difficult and get block up; The compositive respect that the enterprise plans to reach its to design a function in resource encounters very great difficulty; Of the production of the product and lifecycle optimize still come true hard. 3.

The contradictory our country of 2 traditional techniques and new and high technology is in 20 centuries 60 built a wholer manufacturing industry system with 70 time, but the level is very low still, and the development that fails to accelerate the new and high technology such as IT. Accordingly, the production technology of our country is after reforming and opening on system and technology the demand that all cannot get used to market economy. In addition, introducing international advanced technique while, fail to had been handled introduce with self-made relation. Self-made it is basic national policy, introducing should be through digesting, absorb, can achieve dog, the innovation, purpose that produces by oneself. 3.

3 environmental protection and processing spend as attention of society of environmental protection problem not quite rise, the government is being encouraged enhance environmental protection consciousness, from severe processing environment, fulfil the decision-making aspect such as administrative system of job responsibility, still should increase strength. How to use resource effectively, increase to reclaiming the use of material, generate litter wait for a respect without material of social effects of pollution or goods, still very great potential can be dug. 3.

4 unit technologies and the contradiction that the industry combines fall in the drive of current market situation, combining industry product to develop production technology just is the most effective, but our country is in tall, big, essence, pointed, hot, base of the integral level that waits for an industry and achievement of science and technology change an aspect far insufficient still. For example, the numerical control machine tool of our country passes those who count 10 years to tackle key problem, but effect is not quite ideal from beginning to end, worth while and thoughtful, this has technical problem, also have constituent problem and strategic problem. Unit technology is a foundation, but industry whole level is however assure what achievement of science and technology realizes industrialization. 3.

5 talents lack is in our country, state-owned big in the situation that personnel of enterprise major technology lacks for a long time, weakened the development ability of new product new technology greatly. On one hand, the outstanding talent of big batch of institution of higher learing chooses to go abroad, although stay in home also be willing to go more foreign capital enterprise and job of Chinese-foreign joint venture; On the other hand, normal technology grooms the orgnaization often is despised, this makes the skilled worker of our country many prediction of a person's luck in a given year, the overall level that causes manufacturing industry is not high. 4 summary come nearly 229 years, computer of ／ of CAD ／ CAM assists a project (CAD/CAM/CAE) , the computer assists craft to plan (CAPP) , into group technique (GT) , the computer is compositive make (CIM) , flexible make (FM) , face " X " design (DFX) , excellent production (LP, the tremendous potential that shows AMT to go up in industry increasingly. Although some of technology just just starts, but they are in an enterprise pattern of target, management, moving mechanism, crucial technology and manufacturing process respect are having a lot of collective place, these common features made the development way of AMT. Ever the scholar predicts: The happening according to the Industrial Revolution on human history the rule, 21 centuries 50 time will appear new Industrial Revolution. To China, this will be a challenge, also be chance at the same time. Our country should accelerate what be technical innovation system of the center with the enterprise to build, implementation technology innovation, organization innovation, management innovation and talent innovate, the development that is production technology builds a healthy and active environment, from number, essence, extremely, from, collect, net, wisdom, green wait for many respects to go hard, the target that so new Industrial Revolution produces in China will not be a dream.
