Michigan university Summary:The aggregate machine-tool machining center may cause the demand which the processing manufacturing industry adapts changes unceasingly, uses the pool of labor 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-procedure 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 duty which many machine operations could complete, now may concentrate to an engine bed on processes completes. As a result of market demand's unceasing change, the product life cycle is reducing unceasingly, today's market more intense demand multitasking installment concept. Carries out the fine profit management when the entire production environment, compared to having not concentrated 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 insufficiency 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 straight 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 expansion are related. All different size's thing can by the different speed growth. As a result of this reason, needs 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 fall 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 aggregate machine-tools has had the milling and cutting power “the versatile machine”。 According to the material introduced that the most remarkable 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 manual 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 processing scenes.The off-line programming optimization and the NC automatic control system's formation already made 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 have 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 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 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 “the 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 well 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 realize and the full use advanced engine bed flexibility aspect superiority. The work which does to the machine are more, the machine will be more complex, also needs to have the stronger skill person correspondingly to be able to operate it. If machinist past one day operated 3 engine beds, then he has this kind of multi-purpose engine bed now, might produce more components. More importantly, he may draw support from software's help to cause the production efficiency to be higher, regarding transformation processing components preparation, may also establish the processing craft plan. Because the replacement components need to lower 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, the 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 traditional 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. Looking 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. In addition, but should also makes more effort in the cutting tool choice and the programming aspect, must make any model the multi-purpose aggregate machine-tool to succeed, the workshop needs to provide the skilled machinist, has ability and completes many kinds of operations nimbly. Therefore, crosswise 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, this 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 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 tool, may complete the turning on the identical tool rest, boring and drills truncates the processing, is only processes the phase to differ from regarding the work piece angle. The processing operates the difference even confuses is unclear. The new processing cutting tool may complete the milling and the turning. Since has moved 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 principal means that is playing the enormous promotion effect to humanity's production activity and the material civilization. Therefore, the automated technology receives various countries widely to take seriously with more and more applications. The machinery automation (engine bed), mainly refers to the machine-building industry applies the automated technology, realizes the processing object continuously the automatic production, realizes the optimized effective automatic production process, the increase production investment processing transformation and the flow rate. The machinery automation technology's application and the development, are the machine-building industry technological transformations, the technology advancement principal means and the technological development main direction. 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 automation 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 concrete 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 consummation 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 established 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 enormous 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 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 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 accommodating. 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 machine-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 this kind of situation. The initial period take the information integration 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 factory 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 “to run into a wall produces a different product”, transfers pays great attention the information integration the effect, pursues low cost automation LCA (Low Cost Automation) enterprise organizational structure and movement way。 The aggregate machine-tool future development more use transmissions and so on variable speed motor and ball bearing guide screw, will simplify structure, the reduction production metre; Uses the numerical control system and the headstock, the jig automatic replacement system, enhances the craft controllability; As well as integrates the flexible manufacture system and so on. The machine design is through designs the new product or improves the old product to meet the human need the application technical science. It involves the project technology each domain, mainly studies the product the size, the shape and the detailed structure basic idea, but also must study the product the personnel which in aspect the and so on manufacture, sale and use question.Carries on each kind of machine design work to be usually called designs the personnel or machine design engineer. The machine design is a creative work. Project engineer not only must have the creativity in the work, but also must in aspect and so on mechanical drawing, kinematics, engineerig material, materials mechanics and machine manufacture technology has the deep elementary knowledge.If front sues, the machine design goal is the production can meet the human need the product. The invention, the discovery and technical knowledge itself certainly not necessarily can bring the advantage to the humanity, only has when they are applied can produce on the product the benefit. Thus, should realize to carries on before the design in a specific product, must first determine whether the people do need this kind of product. Must regard as the machine design is the machine design personnel carries on using creative ability the product design, the system analysis and a formulation product manufacture technology good opportunity. Grasps the project elementary knowledge to have to memorize some data and the formula is more important than. The merely service data and the formula is insufficient to the completely decision which makes in a good design needs. On the other hand, should be earnest precisely carries on all operations. For example, even if places wrong a decimal point position, also can cause the correct design to turn wrongly. A good design personnel should dare to propose the new idea, moreover is willing to undertake the certain risk, when the new method is not suitable, use original method. Therefore, designs the personnel to have to have to have the patience, because spends the time and the endeavor certainly cannot guarantee brings successfully. A brand-new design, the request screen abandons obsoletely many, knows very well the method for the people. Because many person of conservativeness, does this certainly is not an easy matter. A mechanical designer should unceasingly explore the improvement existing product the method, should earnestly choose originally, the process confirmation principle of design in this process, with has not unified it after the confirmation new idea.Newly designs itself can have the question occurrence which many flaws and has not been able to expect, only has after these flaws and the question are solved, can manifest new goods come into the market the product superiority. Therefore, a performance superior product is born at the same time, also is following a higher risk. Should emphasize, if designs itself does not request to use the brand-new method, is not unnecessary merely for the goal which transform to use the new method. In the design preliminary stage, should allow to design the personnel fully to display the creativity, not each kind of restraint. Even if has had many impractical ideas, also can in the design early time, namely in front of the plan blueprint is corrected. Only then, only then does not send to stops up the innovation the mentality. Usually, must propose several sets of design proposals, then perform the comparison. Has the possibility very much in the plan which finally designated, has used certain not in plan some ideas which accepts. How does the psychologist frequently discuss causes the machine which the people adapts them to operate. Designs personnel''s basic responsibility is diligently causes the machine to adapt the people. This certainly is not an easy work, because certainly does not have to all people to say in fact all is the most superior operating area and the operating process. Another important question, project engineer must be able to carry on the exchange and the consultation with other concerned personnel. In the initial stage, designs the personnel to have to carry on the exchange and the consultation on the preliminary design with the administrative personnel, and is approved. This generally is through the oral discussion, the schematic diagram and the writing material carries on. In order to carry on the effective exchange, needs to solve the following problem: (1)designs whether this product truly does need for the people? Whether there is competitive ability? (2) does this product compare with other companies'' existing similar products? (3)produces this kind of product is whether economical? (4)product service is whether convenient? (5)product whether there is sale? Whether may gain? Only has the time to be able to produce the correct answer to above question. But, the product design, the manufacture and the sale only can in carry on to the above question preliminary affirmation answer foundation in. Project engineer also should through the detail drawing and the assembly drawing, carries on the consultation together with the branch of manufacture to the finally design proposal. Usually, can have some problem in the manufacture process. Possibly can request to some components size or the common difference makes some changes, causes the components the production to change easily. But, in the project change must have to pass through designs the personnel to authorize, guaranteed cannot damage the product the function. Sometimes, when in front of product assembly or in the packing foreign shipment experiment only then discovers in the design some kind of flaw. These instances exactly showed the design is a dynamic process. Always has a better method to complete the de
