摘　　要：对硬脆材料在二维超声电解在线砂轮修整技术(electrolytic in-process dressing,ELID)复合平面磨削条件下的磨削力进行理论研究,建立超声ELID复合磨削力模型。由磨削力公式可知:磨削力除了与超声波的振幅、角频率有关外,同时还受到电流的影响,且随电流的减小,磨削力逐渐增大。在不同磨削深度与砂轮转速条件下采集磨削力,并与理论值进行对比。结果显示:理论值与实测值趋于一致;法向磨削力与切向磨削力均随着磨削深度的增大而增大,随着砂轮转速的增大而减小。Based on theoretical research on grinding force of hard-brittle material in two-dimensional ultrasonic-electrolytic in-process dressing（ELID）composite grinding,the grinding force model of ultrasonic-ELID composite grinding is established.According to the grinding force formula,it is found that grinding force is associated with amplitude and angular frequency of ultrasonic wave.At the same time,grinding force also increases with the decrease of current.Actual grinding force at different grinding depth and wheel speed are compared with those theoretical ones.Results show that both actual and theoretical forces are similar.It is also found that normal and tangential grinding forces increase with the increase of grinding depth or the decrease of wheel speed.
