摘要
为解决多工位复杂形状型槽的难成型问题,设计了一套能够实现多工位同时加工的整体阴极和电解加工(ECM)装置,通过试验优化结构参数;阴极工作型面的设计基于Laplace方程的反问题,从cosθ法求得的阴极雏形出发,通过ANSYS 8.0对间隙电场分布进行有限元计算,与实际工件的边界比较,修改阴极边界,进行下一轮迭代计算。通过工艺试验,采用符合数值模拟结果的阴极加工,检测工件的尺寸和形状,结果符合图纸要求。
A electrochemical machining(ECM) device with an integral cathode was designed to realize machining and shaping contemporaneously for complex groove in multiple workplaces.The structure parameters were optimized after experiments.Based on Laplacian inverse problem of cathode design,the gap potential distribution was calculated by using software ANSYS 8.0 from rudiment cathode obtained according to cosθ method.The cathode boundary was modified according to the difference between the calculation and actual results,and the iteration was carried out repeatedly.The experiment results indicate that the machined workpiece coincides well with the blueprint.
