摘要： 提出了用激光功率谱技术检测砂轮磨损.首先采用"实验统计法"分析砂轮表面的实际功率谱模型,验证了激光功率谱检测原理的正确性,并可由功率谱中心位置到光强下降为最大光强4%位置的距离确定功率谱型的半幅度.其次使用砂轮定度圆盘标定砂轮表面的磨损参数.最后,对砂轮磨耗磨粒切刃的分布进行了检测试验,试验结果与磨削机理相一致.

Abstract: In this paper, grinding wheel wear is measured by laser power spectrum. By analyzing the real power spectrum of grinding wheel wear with "experiment and statistics method", the detecting princple of laser power spectrum is proved, and its half with ξ0 is determined by the spectrum center to the position in which the intensity drops to 4% its maximum intensity. In addition, the grinding wheel parameters with the aluminum disk wheel are calibrated. Finally, the detecting experiments on the worn grains distribution are carried out, and grinding mechanism is identified.
