摘　　要：随着高技术产品的需求对切削表面质量提出了更高的要求,微细磨削成为目前研究的热点之一。为此开展单颗磨粒微细磨削机理分析,并通过试验测试对切削力信号开展滤波分析。研究结果表明:微细磨削实验切削深度误差在0.3%以内,针对测试信号进行低通滤波处理,磨削力信号滤波后表现出来较高的稳定性,信号测试是可靠的。预测值和测试值沿切向和法向达到了良好吻合状态,切向与法向误差分别约为6%与4%,可以精确的衡量出预测磨削力的结果。该研究加入晶粒取向因素的微细磨削力模型可以更加准确预测磨削力,具有很好的推广价值。As the demand of high technology products puts forward higher requirements on the quality of cutting surface,micro-grinding has become one of the hot research spots at present.To this end,the mechanism of single particle micro-grinding is analyzed,and the cutting force signal is filtered by means of experimental test.The results show that the cutting depth error of micro-grinding is less than 0.3%,the low pass filtering is applied to the test signal,the grinding force signal shows high stability after filtering,and the signal testing is reliable.The predicted and tested values are in good agreement along the tangential and normal directions,and the tangential and normal errors are about 6%and 4%respectively,which can accurately measure the results of predicting grinding force.The micro-grinding force model with grain orientation factors can predict the grinding force more accurately,and has a good value for popularization.
