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
A laser power spectrum technique is proposed to detect the wear of grinding wheel. First, the experimental statistical method was used to analyze the actual power spectrum model of the grinding wheel surface to verify the correctness of the laser power spectrum detection principle. The power spectrum can be determined from the position of the power spectrum to the position where the light intensity is reduced to 4% of the maximum light intensity Half the amplitude. Second, use the wheel fixed disc to calibrate the wear parameters of the wheel surface. Finally, the grinding wheel wear abrasive cutting edge distribution test conducted a test, the test results consistent with the grinding mechanism
