【正文】 electric spark forming to process into some major parts, the essential ponents finally processing way. At the same time, to processes the precision the weight not to be able to limit merely to the work piece size precision and the surface roughness, but also should include the profile the GDOP, deterioration level thickness as well as the microscopic crack, the oxidation, the corrosion and 11 so on. (3) processing process micro refinement An electric spark forming processing important application domain is the narrow trough, the deep cavity, the tiny ponents processing, therefore the processing process micro refinement will be the next important development direction. The electric spark processes the mechanism and the conventional electric spark forming processing tiny is same, but has own craft characteristic: Each pulse electric discharge energy is very small, driving fluid circulation difficulty, stable electric discharge gap scope small and so on. Based on these craft characteristic, the tiny electric spark forming processing processing equipment, the driving fluid circulatory system, the electrode preparation and so on inevitably and the conventional electric spark forming processing has the very big difference. Therefore, needs key to study the nonmechanical action and the disturbance to the processing process influence and so on, further enhances the processing efficiency, the processing precision and the processing process stability. (4) application scope expansion At present, not only the electric spark forming processing may process each kind of electric conduction metal material and the plex die space, but also can realize to the semiconducting material, the nonconducting material processing, and has obtained the good processing effect. At the same time, the electrode material type also unceasingly increases. This aspect main trend of development is: Further studies the semiconducting material, the nonconducting material electric spark machining mechanism, promotes its processing efficiency, the processing precision, the processing process stable enhancement, the expansion to be possible to process the material the scope。 Besides the processing plex die space, further realizes to the three dimensional die space, the plex profile processing。 Development performance superior new electrode material. IV、 Operational safety and environmental protection Along with advance in technology and human culture development, the people are more and more high to the working condition improvement and the environmental protection request. The electric spark forming processing as a result of its own characteristic, can have the driving fluid splash, the smog, the noise, the electromagic radiation, the noxious gas inevitably in the processing process and so on the safety factor and the pollution, is noticeable to the operator personal safety and the environment harm. Therefore, for the guarantee electrical finishing industry sustainable development, must act according to ―the green manufacture principle‖, the realization resources most effective use and the reject threshold produces with the emissions. Should take following measure specifically: ① Seal engine bed work area. This is advantageous to the improvement driving fluid, the smog, the electromagic radiation and so on to the human body, the engine bed, the working conditions pollution, is advantageous in the operating process prevented receives an electric shock the danger as well as to the noxious gas centralized processing emissions。 ② Vicarious technical utilization. For example, the environmental pollution which creates for the reduced use driving fluid, may in the guarantee processing efficiency, the processing precision, the processing cost as well as under the processing process stable premise, selects the pollution small driving fluid as far as possible, simultaneously should study, the development vigorously does not use the driving fluid the formed processing technology。 ③ Reject 12 postprocessing. The waste liquid, the waste gas produces which after the processing in must pass through processing to be able to discharge. Needs to point out specially, has pollutant reasonable processing to the processing process, not only is advantageous to the enhancement work security, the reduction environmental pollution, but also is advantageous in improves operator39。s working conditions, causes when the operator work the mood is happy, this regarding enhances the electrical finishing industry the social image and the market petitive power also is extremely beneficial. V、 Conclusion The electric spark forming processing technology holds the important status in the manufacturing industry domain, is realizes difficultly to process the material, the plex ponents precise processing effective method. The researcher should profit from other processing technological development the success experience, enhances strong points and avoid weaknesses, uses the modern science and technology development fully the related achievement, studies the electric spark in the deep person to discharge the mechanism in the foundation, the instruction electric spark forming processing craft theory and the control theory research, improves the engine bed structure and the design method, establishes based on the PC machine open numerical control system, the realization intelligence control technology and the electric spark forming processing technology organic synthesis, simultaneously takes the operational safety and the environmental protection highly, prehensively impels an electric spark forming processing technology quicker development.
