1、Multi-purpose aggregate machine-tool timeTimothy and Jacobs, Denis” A receives then then, outstanding Philip U.S.A. Michigan universitySummary:The aggregate machine-tool machining center may cause the demand which the processing manufacturing industry adaptschanges unceasingly, uses the pool of labo
2、r power effectively, and has the competitive power in global scale”s market. Key word: Make the lathe up Regarding the multi-purpose aggregate machine-tools, in the industrial field has many names to describe it, like “the multitasking installment”, “the multi-purpose engine beds”, “the multi-proced
3、ure production system” and so on, it may be called the processing domain truly the nova, may reduce the cost, the simplified disposition, and has maintained in the US territory produces. In the past only then used the dutywhich many machine operations couldcomplete, now may concentrate to an engine
4、bed on processes completes. As a result of market demand”s unceasing change, the product life cycle is reducing unceasingly, today”s market more intensedemandmultitaskinginstallmentconcept.Carriesoutthefineprofit management when the entire production environment, compared to having not concentrated
5、the components processing to a machine on completes a finer profit. Some tradition”s manufacturing industry manufacturer thought that the multi-purpose aggregate machine-tools are too complex, very difficult to find the appropriate operators also the difficult problem innovates on the spot on the in
6、sufficiency for the metal working basic principle and in the Production workshop related new engine bed use solution aspect training. Intuition type technical control The equipment use “carries off the quantity of heat” the type design, has different material which the lathe bed, the steeliness stra
7、ight line rolling guide, on the steeliness revolving tool box saddle, the equipment uses, all these combine make an engine bed together. These with the thermal conductivity, the volume expansionare related. All different size”s thing can by the different speed growth. As a result of this reason, nee
8、ds to make the hot friendly engine bed, with the aim of knowing gives off heat the weak point in where, can compensate through the reasonable engine bed design. The part is the entire journey movement. The engine bed glide produces rubs and transform hotly. The machining produces the hot filings fal
9、l to the different place, the refrigerant can mix in the entire process in which. Will present the different temperature province continually on the cutting tool, will therefore also have many things to have the influence to the thermostability. The cutting tool technology turned the multi-purpose a
10、ggregatemachine-toolshashadthemillingandcuttingpower“theversatile machine”.Accordingtothematerialintroducedthatthemostremarkable characteristic is in these engine bed whole has the intuition. The anti-collision preservation technology was already mature, in certain circumstances, even if uses the ma
11、nual operation pattern, can also avoid the occurrence which collides. Because the control software has the very good intuition, the user operation friendly degree unceasingly is also enhancing. Believe the multi-purpose aggregate machine-tools by its survivability world-wide in the more different pr
12、ocessing scenes. The off-line programming optimization and the NC automatic control system”s formation alreadymade this technology to be easier to accept, when therefore uses the procedure when the engine bed, does not need to spend many time tune-up procedure and confirmed that some part does not h
13、ave the question. If components need to provide the high and low two revolving tool box saddle simultaneously to carry on the rough machining, in this kind of situation the programming is quite difficult, because it needs two revolving tool box saddles also to feed. The AdMac system may realize tool
14、 rest”s automatic programming which simultaneously feeds to these, and can cause the correct main axle speed, the correct feed rate and so on all parameters to realize the synchronization. Okuma Corporation”s collision avoidance system design based on actual processing operating mode anti-collision
15、simulation, therefore, if the operator has installed the wrong cutting tool or has established the wrong parameter, the control system will examine and prevents the engine bed to enter the processing condition. Through cooperates with the Siemens, INDEX Corporation may provide the 3D pattern now “th
16、e hypothesized engine bed”, has custom-made according to some specific model”s engine bed. The result indicated that the simulation processes not only the fabricated parts and the actual end product is similar, is the one-to-one copy simply. The intuition type control interface, the simulation as we
17、ll as other software technique are progressive, the more Production workshops have opened wide the front door to the multi-purpose aggregate machine-tools, but if does not have the corresponding knowledge to train and to solve the question creativity, the manufacturer is also very difficult to reali
18、ze and the full use advanced engine bed flexibility aspect superiority. The work which does to the machine are more, the machine willbe morecomplex,alsoneeds tohave thestronger skillperson correspondingly to be able to operate it. If machinist past one day operated 3 engine beds, then he has this ki
19、nd of multi-purpose engine bed now, might produce more components. More importantly, he may draw support from software”s help to cause theproductionefficiencytobehigher,regardingtransformationprocessing components preparation, may also establish the processing craft plan. Because the replacement com
20、ponents need tolower 3 main axles, therefore before replacing the components, the workshop should process as far as possible many components. Regarding the multi-purpose engine beds, the transformation components speed is quick, the production batch of time interval is shorter, the stock is lower, t
21、he production efficiency is higher. Can use multi-purpose engine bed”s some workshops fully, very quick will discover the post function the unification. Now, a workshop may only use an operator, an adjuster and a programming teacher, in the future these 3 work definitely may do by a person. In the t
22、raditional post description the machinist will transit becomes one to adjust engineer, if this engineer the familiar components processing programming, that were also more ideal. Regarding such transformation, training has been simple, so long as trains 1 individual line, but is not 3 individuals.Lo
23、oking from the long views, this will provide to the people the higher post degree of satisfaction. When adjusts engineer to be responsible to process the programming, and pays attention to the components processing personally time the entire process, he completely has become this components control.
24、 In addition, but should also makes more effort in the cutting tool choice and the programming aspect, must make anymodel the multi-purpose aggregate machine-tool tosucceed, the workshop needsto provide the skilled machinist, has ability and completes many kinds of operations nimbly. Therefore, cros
25、swise training was at any time in the past more important. Regarded as the milling and the lathe work the different discipline the viewpoint never to return. Regarding the programmers, this belongs to their time. Regarding personnel who will program, will understand the engine bed and controls it, t
26、his will be their ability manifestation. The cutting tool will choose most people not to install the passenger vehicle tire to the race car on, but processed the cutting tool to have such situation. The cutting tool should match with the new engine bed, is conceivably redundant on the new engine bed
27、 uses the old cutting tool to the production efficiency influence. In order to match the multi-purpose aggregate machine-tools, the new cutting tool and the cutting tool adapter technology was already developed. At present the industrial field is developing the development the processing cutting too

The processing operates the difference even confuses is unclear. The new processing cutting tool maycomplete themillingand th
29、eturning. Since hasmoved the technology (engine bed) is this century develops is extremely rapid and one of influence enormous science and technology. The modern automation technology is one kind of completely new productive forces, is one of direct creation public wealth principalmeansthatisplaying
30、theenormouspromotioneffecttohumanity”s production activity and the material civilization. Therefore, the automated technology receives various countries widely to take seriously with more and more applications.As machine tool has a strong interchangeability, it is necessary to improve the general le

Complete specification, dynamic and static performance parameters of advanced.In the machinery manufacturing industry, accounting for about 70% of small and medium batch production, in some of the production enterprises, such
32、as machine tools, valve industry, with its key process using combination of machine tools. The development of adjustable, quick transfer, assembly and flexible to adapt to the characteristicsofmulti-speciesprocessingmachinetoolisveryurgent. Turret machine tool spindle box, can be combined for box-ty

Machinery automation technical standards, not only affects the entire machine-building industry the development, and has the very tremendous immediate influence to the national economy various departments” technology advancement. Therefore, develops our country”s machine-building industry automat
39、ion technology, conforms to our country socialism basic principle, conforms to our country modern production law of development. How to develop our country”s machinery automation technology (engine bed), here has the technical policy question, should be realistic, all embark from our country”s concr
40、ete national condition, do each foundation work, takes the China”s road of machinery automation technological development. The domestic and foreign industry history tells us, realizes the machinery automation is from to high-level, from simply to complex, from is preliminarily imperfect the consumma
41、tion the developing process. After machine”s operation uses the automatic regulator, the production method only then gradually transits from the mechanization to the mechanism control (tradition) automated, the numerical control automation, the computer control automation. Only then after having est
42、ablished the Automated factory, the production process can overall automate, can make the productivity to enhance comprehensively, achieves automated the high-level ideal stage. The machinery automation technology first starts from the 1920s in the machine manufacture cold finishing production in en
43、ormous quantities process to develop the application, after in the 60s, to adapt the market demand and the change, for the enhancement machine-building industry to the market nimble rapid reaction”s ability, starts to establish the variable automation production system, namely revolves the computer
44、technology the flexible automation. It is in the manufacture system invariable or in the change small situation, the machinery equipment either production management process through the automatic detection, the information processing, the analysis judgment realizes the anticipated operation or some
45、kind of process automatically, and can from make one kind of components to transform automatically to makes another kind of different components. The social practice proved that under this kind of definition”s manufacture system automation and the contemporary majority enterprises are not actually a
46、ccommodating. The contemporary society also not in the science and technology, the material and the personnel aspect prepares to realize this automated condition, insists such to do only meets the wasted effort. This kind of situation is not exceptional regarding the separate production method”s mac
47、hine-building industry, the difficulty can bigger. In the 80s internationally appeared started to use computer integration manufacture system CIMS (Computer Integrated Manufacturing), the flexible automation production pattern also had thiskind of situation. The initial period take the information i
48、ntegration as a key point, take the high automaticity as the characteristic, but in realized in the process to encounter the difficulty. In view of the fact that realizes the large amount investment which the computer integration manufacture system”s automation overall needs (an overall Automated fa
49、ctory to spend several hundred hundred million US dollars, flexible manufacture system regular price is 600 25,000,000 US dollars), undertakes the huge risk, in addition questions and so on technical difficulty and reliability, the world industrially advanced country started “torun into a wall producesa dif ferent product”, transfers pays great attention the information integration the effect, pu
