1、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 la
2、bor power effectively, and has the competitive power in global scales 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-procedu
3、re 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
4、bed on processes completes. As a result of market demands unceasing change, the product life cycle is reducing unceasingly, todays market more intense demand multitasking installment concept. Carries out the fine profit management when the entire production environment, compared to having not concen
5、trated the components processing to a machine on completes a finer profit. Some traditions 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
6、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
7、 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 sizes thing can by the different speed growth. As a result of this reason
8、, 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 filing
9、s 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-purp
10、ose 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 circumstanc
11、es, 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 i
12、n the more different processing scenes. The off-line programming optimization and the NC automatic control systems 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 th
13、at 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
14、system may realize tool rests 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 Corporations collision avoidance system design based on actual processing operating
15、 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 t
16、he 3D pattern now “the hypothesized engine bed, has custom-made according to some specific models 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
