Study On Properties Of Current Distribution Along Micro-profile In Processing Of Electrochemical Finishing

Electrochemical finishing technology with the good surface quality make its process method has been increasingly widely application , and has become one of the processing technology manufacturing , a lot of research results indicate that using electrochemical finishing technology not only improves parts surface machining accuracy , but also can effectively increase the use of parts performance.Electrochemical finishing method get the rapid development , greatly improved the machined surface quality in machinery parts processing , get the application in machinery parts processing because it do not suffer influence of parts surface hardness , and can make parts processing surface obtain good micro geometric profile. Study shows electrochemical finishing not only can significantly improve the machined surface machining parts, and still can improve the quality of parts processing precision in different degree.The results of the study shows that , electrochemical finishing the whole process is a process of workpiece anticathode surface micro geometric profile from peak shape into arc shape of the fillet process , workpiece surface morphology of anode geometry of microscopic affect not only improve round , but also leveling effect affect machining accuracy. The processing of electrochemical light mechanism is leveling influence surface quality and machining precision of the important factors that affect leveling effect by many factors , Such as , electrolyte quality score, current density , etc , but the other conditions uncertain anode micro geometric profile change on leveling effect the most obvious. Related the analysis of experimental results also indicated that the beginning of the whole processing in electrochemical light, leveling effect increased significantly , but as the light is on , the processing of leveling effect improve is not obviously ; meanwhile , the surface obtained by microscopic geometric profile for a round shape peak deformation obviously, in the small gap conditions , the geometric profile on micro change affects current distribution explain the current distribution affecting leveling effect and surface quality , Therefore , in order to improve the processing leveling electrochemical light effect is necessary to study the whole process of electrochemical finishing of current field distribution characteristics. According to the change of whole processing and electrochemical light microscopic surface outline.This paper Puts forward The cone and half a sphere Two kinds of surface micro geometric morphology, studied from the perspective of microscopic geometry electrochemical finishing the whole processing leveling process workpiece anticathode surface and the variation of microscopic geometric profile influence.Based on surface microstructure geometric shape of the cone proposed and half sphere according to relevant electrodynamics knowledge current field established the mathematical model, and analyzes the whole process of electrochemical light changes in the current field distribution characteristics. The results of the study show that, peak shape to strengthen microscopic geometry contour surface electrochemical dissolution, be helpful for improving leveling effect, arc shape surface micro geometric profile weakening electrochemical anode dissolution, is not conducive to improving leveling efficiency using relevant numerical simulation software simulation peak shape and arc shape two surface micro geometric profile charge distribution and charge density distribution curve, verify the above process electrochemical mechanical light the whole processing process, mechanical function not only has the role of scraping membrane, but also has made the surface of microscopic geometric outline the role of peak.
