摘要
数控电解复合铣削加工用阴极的流场决定了一次加工的深度、加工效率和加工精度。通过FLUENT软件对3种不同类型出液口阴极进行流场数值模拟分析并比较、修正,最后通过实验验证数值分析的正确性。针对不锈钢整体叶轮,成功设计了切深65 mm的螺旋型喷缝阴极,在表面质量和精度满足粗加工要求时,最大进给速度为0.7 mm/min,且稳定性和重复性很好。
The flow field of NC electrochemical milling cathode determined milling depth, efficien- cy and precision. Three types of cathodes with different liquid outlet were simulated by Fluent soft, the results were compared and modified. At last, the correctness of numerical simulation was tested by experiments. To solve the problem of how to machine stainless steel integral impeller, the type of spir- al liquid outlet cathode which could mill 65mm depth was designed. When surface quality and accuracy meet the requirements, the fast milling speed was 0.7 mm/min, and the stability and repeatability were perfect.
