提出了一种电解加工工具阴极设计的新方法。该方法将生产实际中制造阴极的过程再现于计算机上。采用有限元求解拉普拉斯方程得到加工间隙中的电位分布,通过不断地将获得的等位线与理想工件边界进行比较,将得到的差值映射到阴极端用来指导阴极的修整,直到工件阳极端的差值小于所允许的值。由于该方法的数值计算是基于拉普拉斯方程的正问题进行的,具有易于处理复杂边界、收敛性好、精度高的特点。同时进行了试验,验证了该方法的正确性。
A new method for cathodic design of electrolytic machining tools was proposed. The method reproduces the process of actually making the cathode in a production computer. The finite element method was used to solve the Laplace equation to obtain the potential distribution in the machining gap. By continuously comparing the obtained equipotential lines with the ideal workpiece boundary, the difference obtained was mapped to the cathode end to guide the trimming of the cathode until The difference between the anode and the workpiece is less than the allowable value. Because the numerical calculation of this method is based on the positive problem of Laplace equation, it has the characteristics of easy processing of complex boundaries, good convergence and high precision. At the same time, experiments were carried out to verify the correctness of the method.
