【正文】 l 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 plete 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 pletely new productive forces, is one of direct creation public wealth principal means that is playing the enormous promotion effect to humanity39。s engine bed. The result indicated that the simulation processes not only the fabricated parts and the actual end product is similar, is the onetoone 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 multipurpose aggregate machinetools, 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 plex, 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 multipurpose engine bed now, might produce more ponents. More importantly, he may draw support from software39。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 Corporation39。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 pensate 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 multipurpose aggregate machinetools 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 anticollision 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 multipurpose aggregate machinetools by its survivability worldwide in the more different processing scenes. The offline programming optimization and the NC automatic control system39。s market more intense demand multitasking installment concept. Carries out the fine profit management when the entire production environment, pared to having not concentrated the ponents processing to a machine on pletes a finer profit. Some tradition39。s market. Key word: Make the lathe up Regarding the multipurpose aggregate machinetools, in the industrial field has many names to describe it, like “the multitasking installment”, “the multipurpose engine beds”, “the multiprocedure 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 plete, now may concentrate to an engine bed on processes pletes. As a result of market demand39。Multipurpose aggregate machinetool time Timothy and Jacobs, Denis39。 A receives then then, outstanding Philip . Michigan university Summary:The aggregate machinetool machining center may cause the demand which the processing manufacturing industry adapts changes unceasingly, uses the pool of labor power effectively, and has the petitive power in global scale39。s unceasing change, the product life cycle is reducing unceasingly, today39。s manu
