摘　　要：从磨削过程中振动功率的角度研究了在线电解修整(ELID)内圆磨削轴承外圈时,磨削深度和砂轮进给速度对磨削表面波纹度的影响,并通过不同的磨削参数组合,从磨削过程中氧化膜状态和材料去除机理等角度分析比较了磨削深度和砂轮进给速度对磨削过程影响的程度。试验结果表明,磨削深度的作用更重要,在实际ELID内圆磨削过程中可以先采用较大的磨削深度以实现高的材料去除率,再采用较小的磨削深度以提高表面质量,并且在ELID磨削过程中可以通过振动的大小来预测加工后工件表面的波纹度大小。It was investigated that the influences of depth of cut and wheel feed rate on internal ELID grinding based on the vibration signals. With a series of experiments using different parameter combinations, the effects of depth of cut and wheel feed rate on ELID grinding were compared. The experimental results show that depth of cut has a greater influence than that of wheel feed rate. In actual process a big depth of cut can be firstly used to obtain a large material removal rate, then a small depth of cut can be used to obtain a good surface quality, and the amplitude of vibration in process can predict the waviness on workpiece surface.
