|
摘要
为实现S-03特种钢的高效、高表面质量电解加工,采用正交与灰关联理论相结合的方法,先进行了Na NO3、Na Cl O3电解液预试验研究,分析了电压和进给速度对材料去除率、表面粗糙度及侧面间隙的影响规律。为进一步提高加工效率,在复合电解液中添加Na Cl,研究电流密度对表面粗糙度的影响规律。结果表明:采用质量分数5%Na Cl+16%Na NO3+4%Na Cl O3的复合电解液,在电压24 V、电解液压力0.8 MPa、电解液温度30~35℃的条件下,实现了进给速度2.4 mm/min、表面粗糙度Ra0.4μm的高效、高表面质量加工。
In order to achieve high surface quality and machining efficiency for electrochemical machining S-03 special steel,the orthogonal design and grey relational analysis methods were adopted.First of all,using Na NO3、Na Cl O3 electrolyte,the pre-experiment is carried out. The influence rule of voltage and feeding speed on material removal rate,surface roughness and side clearance were analyzed. In order to further improve the processing efficiency,the electrolyte composite is added the Na Cl. The influence of current density on the machined surface quality was also researched. The results show that under the conditions of 24 V voltage,0.8 MPa electrolyte pressure,the electrolyte temperature from 30 ℃ to 35 ℃ and the electrolyte composite of 5 %Na Cl+16 %Na NO3+4 %Na Cl O3,the feed rate of 2.4 mm/min and the surface roughness of Ra0.4 μm were acquired.
