Electric spark forming processing craft trend of development
Through processes the mechanism to the electric spark forming the research, further promulgates the electric discharge process the inherent laws, and take this as the instruction, impels the electric spark forming processing craft to the high efficiency, Cnc machining the high accuracy, the low loss direction to develop, meanwhile should pay attention to the micro refinement processing aspect the development.
(1) processing process highly effective
Not only the processing process highly effective manifests in through the improvement electric spark machining servosystem, the control system, the driving fluid system, the engine bed structure and so on, reduces the above factor to the electric spark forming processing efficiency influence, enhances, the precision work efficiency thickly in under the guarantee processing precision premise, meanwhile should reduce the non-cutting time as far as possible (for example programming time, electrode and work piece localization time, maintenance time and so on), this needs to strengthen the engine bed the automatic programming function, expands the engine bed online backstage programming ability, the improvement and the development suitable electrode and the work piece positioning device. In the engine bed maintenance aspect, should strengthen the engine bed the multimedia functions and the online help function, regarding the common breakdown, the operator may act according to the computer prompt realization trouble shooting directly,Cnc machining simultaneously this is also advantageous in strengthens the engine bed the feasibility and operator's operation skill.
processing process precision Through uses a series of advanced processing technology and the technique, at present the electric spark forming processing precision had the comprehensive enhancement, some has been possible to achieve the mirror surface processing level. But looked from the overall that, the vanguard technology insufficiently is also mature in the actual production application and widespread, therefore has the necessity comprehensive impetus to have the vanguard technology further consummation and to develop to the industrial production direction. In the guarantee processing speed, under the processing cost premise, makes the electric spark forming processing the precision level further to enhance, causes the electric spark forming to process into some major parts, the essential components 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 so on.
(3) processing process micro refinement An electric spark forming processing important application domain is the narrow trough, the deep cavity, the tiny components 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 non-mechanical 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 complex die space, but also can realize to the semiconducting material, the non-conducting 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 non-conducting 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 complex die space,Cnc machining further realizes to the three dimensional die space, the complex profile processing; Development performance superior new electrode material.
