摘要
为了加工出高精度的微槽结构,基于分层铣削的方法对304不锈钢工件进行微细电解铣削加工试验研究。对比分析了分别将硫酸溶液和硫酸-乙醇溶液作为电解液的微槽加工精度,结果表明,硫酸-乙醇复合电解液能够减少杂散腐蚀,提高加工定域性,减小微槽的表面粗糙度。通过单因素试验研究微细电解铣削加工中不同工艺参数对微槽加工精度的影响,得到了优化的组合工艺参数,在该组合工艺参数下,加工出尺寸为260μm×93μm×42μm、截面成型角度为114°和表面粗糙度Ra为0.39μm的微槽。
In order to machine high precision microgroove structure, the experiment of electrochemical micromilling of 304 stainless steel was carried out by using the method of layer milling.The machining accuracy of microgrooves was compared and analyzed between H_(2)SO_(4)solution and H_(2)SO_(4)-C_(2)H_(5)OH solution.The results showed that H_(2)SO_(4)-C_(2)H_(5)OH compound electrolyte could reduce stray current corrosion, improve the localization of machining and decrease the surface roughness of microgrooves. The influence of different process parameters on the machining accuracy of microgroove in electrochemical micromilling was studied by single factor experiment, and a better combination of process parameters was obtained. Under this combined process parameters, the microgroove with size of 260 μm×93 μm×42 μm, cross section angle of 114° and surface roughness of Ra 0.39 μm was machined.
