2、achine-tools has many names to describe it in the industrial field.It likes“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 and reduce the cost, the simplified disposition and has
3、maintained in the US territory produces. In the past only they used the duty which many machine operations could complete, now it may concentrate to an engine bed on processes completes. As a result of market demands unceasing change, the product life cycle is reducing unceasingly, todays market mor
4、e 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 traditions manufacturing industry manufacturer thought that t
5、he 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. I
6、ntuition 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
7、. 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, 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 reas
8、onable 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 conti
9、nually 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 mos
10、t 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 山东建筑大学毕业设计 外文文献及译文 - 2 - which collides. Because the control s
11、oftware 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 systems
12、 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 sad
13、dle 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 rests automatic programming which simultaneously feeds to these, and can cause the correct
14、 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 mode anti-collision simulation, therefore, if the operator has installed the wrong cutting tool or has establishe
15、d 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 models engine bed. The
16、 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
17、 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
18、 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
19、 may draw support from softwares 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
