Multi purpose aggregate machine tool time Timothy and Jacobs Denis A receives then then outstanding Philip U S A 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
