Abstract

This study investigates the discharge energy distribution during Powder Mixed Electrical Discharge Machining (PMEDM) at different values of pulse duration, peak current and powder concentration. A finite element method (FEM) based numerical model has been developed to estimate the power distribution factor by reverse simulation. The developed model has been used for determining the fraction of discharge energy distributed to the electrodes. The model and experimental values of total fraction of discharge energy are in close agreement with the error varying between 0.47 % to 14.04 % for tool and 0.82 % to 9.82 % for workpiece. Parametric influence on components of discharge energy has also been discussed.

粉末混合电火花加工中能量分布的数值和实验研究

本研究探讨了粉末混合放电加工（PMEDM）在不同脉冲持续时间、峰值电流和粉末浓度值下的放电能量分布。通过反向模拟，开发了一个基于有限元法（FEM）的数值模型来估算功率分配系数。所开发的模型用于确定分布在电极上的放电能量分数。放电能量总分量的模型值和实验值非常接近，对刀具的误差在 0.47 % 到 14.04 % 之间，对工件的误差在 0.82 % 到 9.82 % 之间。此外，还讨论了参数对放电能量成分的影响。
