01mm with the problem, the research and development of this product line indicates the contribution of national defence spends an enterprise of domestic machine tool to promote steadily, more representing the step with fast respect of technology of core of our country control. Aerospace manufacturing industry is well-known to the demand of the machine tool, the scale of the titanium alloy that plane structure place of future employs and composite material will promote substantially, the demand of aluminium alloy can drop somewhat, the treatment machine tool of titanium alloy and composite material can accept favour gradually. Be aimed at this one trend, in have the aid of of limited company of nimble machine tool the chance research and development with 915 great and special science and technology an AB that is used at titanium alloy treatment places a 5 axes linkage machining center, its process capability and abroad comparative with type machine tool, can replace the entrance machine tool of this type completely. In spaceflight domain, the housing of large carrier rocket has very major use aluminium alloy to make, before craft uses cankerous treatment technique, although this method can satisfy spaceflight requirement, but insufficient to the quality control existence of housing. Use the bridge-type dragon door that is used at aviation industry at the treatment of rocket housing, promote housing the quality of workpiece greatly, the error is controlled accurately in 0.
05mm less than. In research and development of limited company of nimble machine tool GMC50100U is used at Shanghai the treatment of housing of carrier rocket of some spaceflight enterprise, its machine quality and efficiency to obtain promote substantially. Composite material quality light, intensity is high, be hard to machine quite, characteristic and complete distinction at metallic stuff. The group that Dalian manage is versed in the Gao Hang of the university teachs place to guide pursues the research of difficult treatment material all the time, machine craft and respect of treatment cutting tool in composite material especially, successfully composite material get enlarge to wring aperture craft successful and compositive finish on a cutting tool, developed the professional and compound cutting tool that is used at this kinds of craft. The one-time compound treatment that completed bigger to difficulty composite material and titanium alloy matrix tackles key problem, in domestic composite material treatment domain is having richer experience, offerred more solution for domestic aerospace company, from application realistic point of view solved crucial treatment difficult problem for aerospace company. Have what composite material machines a solution to include machine tool, craft, cutting tool inside the development trend that package solution makes material of prospective difficult treatment necessarily. The development trend of Nextpage future machine tool although the development direction that intelligence is changed and green environmental protection is sure to make prospective machine tool, will tell from macroscopical angle, the pattern of prospective machine tool also should undertake be examininged afresh, especially reasonable arrangement development is high-grade machine tool, intermediate the devoted proportion of machine tool, cheap machine tool. In whole manufacturing industry, have backbone effect truly should be those who have better precision and more reasonable price is intermediate machine tool, can go up dimensions estimates ground put into production group by group; The certain and crucial segment that the high-grade machine tool with high accuracy and high price uses in manufacturing industry process only, the amount is little, be hard to become dimensions, production value is finite; Low end the machine tool is used in precision to ask inferior or those who do not have a requirement is low only technical trade, its are overall value is inferior. Reliability is accordingly higher, integral performance is higher, the price is more reasonable intermediate the major proportion that the machine tool will hold prospective machine tool to yield. The angle that develops from the technology of narrow sense will tell, the intelligence that prospective machine tool develops is changed, its concept has each different, if MAZAK is right,the requirement of intelligent machine tool reflects the function in 7 respects: Intelligence is changed prevent interference function, intelligence to change hot screen function, vibration to check control balance of workbench of function of function, main shaft monitoring, turning is maladjusted detect function, maintain monitoring function and speech navigation function. These intelligent functions are the function that the machine tool of MAZAK has had, so what does future still need more intelligent function? Compositive intelligence changes advanced technology will become future to develop a tendency. The treatment of the spare parts of a product should pass the course that be as follows: The design of part drawing paper, craft weaves, the choice of parameter of the work out of the program, cutting, and the test that has iteration even, in order to assure the rationality of treatment program. The development that handles chip technology as informatization high speed reachs the application on the machine tool, the control of prospective machine tool is finished through handling chip quickly, be in at the same time interior of machine tool system is compositive and advanced machining complex. This system backstage runs large database, cutting tool all craft information type a database automatically, use at advanced machining complex to be called in real time. Before undertaking machining, need to adopt product model exterior interface to input advanced machining complex only, the system can discern digital model automatically, the angle that be led from treatment effect and machines quality undertakes those who machine plan automatically make. Take cutting tool news through be being read from cutting tool database, use the information such as the every tine feed of cutting tool at the system to machine the program of orbit, create optimized program automatically, handlers needs to choose a few key-press through simple ground only, with respect to the selection that can complete whole treatment plan, through emulating the completes workpiece part automatically by the machine tool treatment after the examination affirms, believe this function is in before long the development that carries pair of CAD/CAM systems to have development in the future can come true. The separate course that 1 product research and development and enterprise produce the problem that industry of current machine tool exists is some nearer of year of country policy guide the construction that reachs corresponding platform effectively, impetus of machine tool development is swift and violent, achievement of its scientific research and economic dimensions also make a person gratified. But hard to avoid can be put in a few problems, the issue with company product research and development and for instance separate production. The occurrence of this kind of phenomenon also is the problem that domestic company exists generally. This kind of problem results from of yield of firm of current home machine tool swift and violent rise. In heavier production the task falls, how finish machine tool product efficiently quickly yield, decided the enterprise is in the position of the market. The condition that drops products plan index to get used to production happens from time to tome, the sheet that causes a product character drops, the character of integral machine tool also happened to reduce. The fact of machine tool industry that this kind of phenomenon that hangs gives to provide industrial machine tool for manufacturing industry now is belonged to not should, also appear in the national defence domain such as aerospace, must make us anxious. 2 technologies and product depart are in the process of research and development of the product, appeared at present a kind of strange phenomenon. The design rate of a kind of product is very rapid, the design of a new product is little criterion a few days, many a month. Rate of so rapid research and development must let person exclaim, did ability of its research and development reach certain state truly? Actual rather, the research and development of a lot of products appeared " know its not to know its the reason why like that " common fault, if this problem spreads, consequence will be unimaginable. Always go counterfeiting, so the creativity that designed personnel to lose his, overly depends on the product of figuration, the character that can let a product appears the aspect that cannot control, can undertake changing setting is out of shape to existing machine tool only, without redesigned creativity, what also lacked innovation naturally is essential, do not have vitality naturally without innovation product research and development, also do not have durative, more the advanced machine tool that He Tanchao jumps over a developed country.
