外文翻译--电火花成形加工技术的现状与发展趋势内容摘要：

ng processing basic theory research not yet made the substantive progress, although some scholars to the processing process electric discharge trace, the material eclipse eliminated the principle and so on to propose some new views, but obtained the significant breakthrough by no means in the electric spark machining mechanism research aspect. The more active research area mainly concentrates in the processing craft theory and the control theory aspect. In the processing craft fundamental research aspect, how does the research 9 hot spot mainly is enhance the electric spark forming processing the surface quality and the processing speed, reduces the loss, the development electric spark machining scope, as well as exploration plex, tiny structure processing method and so on. Will apply through the research results in the production practice, will prehensively enhance the electric spark forming processing workability. In the control fundamental research aspect, the intelligent control always is the research key. The domestic and foreign production new electric spark forming processing engine bed mostly has used the intelligent control technology, this technical application makes the engine bed operation to be easier, requests to the operator lowly. At the same time, the intelligence control system has from the learning capability, but the online automatic monitor, the adjustment processing process, realizes the processing process optimized control. Although the electric spark forming processing fundamental research in aspects and so on basic theory, processing craft theory, control theory all has certain development and the enhancement, but the processing craft theory, the control theory need to obtain the further full scale development, must have the breakthrough in the entire electric discharge process mechanism research. Therefore, the electric spark forming processing fundamental research trend of development will be further is discussing the processing craft theory and the control theory, enhances the electric spark forming processing workability and the processing scope, obtains the better control effect at the same time, key research electric discharge process mechanism. The electric spark forming processing mechanism research has not made the unprecedented progress the primary cause except outside the electric discharge process itself plexity, randomness, but also because the research technique and the method lack the innovation. Therefore, it is necessary to profit from other research area the success experience, directs the human advanced research technique and the experimental technology, the victory tradition research technique limitation, the deep person analysis and the revelation entire electric discharge process intrinsic essence, the establishment may reflect objectively the electric discharge process rule the theoretical model, instructs the electric spark forming processing craft theory and the control theory research, but the puter simulation technical possibilities realizes this process effective tool. 2. electric spark forming processing equipment structure improvement The model modern machining engine bed development experience, the electric spark forming processing equipment develops to the numerical control direction is a irreversible tendency. On the one hand should by the high accuracy, the high velocity, change into the pursue goal automatically, seizes the market by the technical superiority。 On the other hand should consider fully the equipment the performance price pared to, through to the engine bed function reasonable localization, makes the structure improvement and the modular design, uses the 10 open numerical control system, enhances rationality which the engine bed designs, provides by the lowest price and the enough function to the user may satisfy each kind of electric spark forming processing engine bed which the different processing needs. Modern machining technological development impact, before suits uses the electric spark machining a part of processing domain to substitute gradually for the machining way. But, the modern science and technology development proposed to the ponents manufacture precision a higher request, each kind of high performance material application is day by day widespread, simultaneously, some ponents structure tends to the plication, the microminiaturization, thinly, this all causes the machining technology to be restricted in certain processing domain application, but these are exactly the electric spark forming processing technical superiority, also is it has the existing space and the development potential reality basis. For the prehensive impetus electric spark forming processing equipment technology advancement, while uses the advanced control system, the engine bed structure design also needs further to consummate, its main development direction displays in following two aspects: (1) straight line servosystem application The electric spark forming processing equipment uses the straight line electrical machinery servosystem to be possible to cause the workability to obtain the distinct improvement, the concrete manifestation is: May realize the axis direct translation, omits a guide screw nut transmission link, thus guarantee axis high speed movement。 Uses the straight line electrical machinery and the slide integration structure, may eliminate between the slide and the electrical machinery because of has the machinery lag in response phenomenon which the middle link causes, enhances the system the sensitivity, reduces the dynamic response time, the guarantee processing process stability。 The straight line electrical machinery servosystem mode of motion had decided its position examination link must use the straight line position feedback part, the rea。
