利用ＣＯ２激光对树脂结合剂金刚石砂轮片的表面进行了扫描试验，对扫描前后砂轮片的表面三维形貌进行了测试分析，研究了激光脉冲频率和占空比等参数的影响。结果表明，尽管平均扫描能量密度一定，但频率和占空比对修锐效果均会产生影响，其中频率的影响更为显著。同时，通过使用铝工件和砂轮片的相对刻划试验，对不同扫描条件下刻划时的切向力与法向力之比进行了对比分析，发现由于该力比可以有效地反映出砂轮片的切削性能，因此可以用来对修锐效果进行定量评价。
The CO2 laser was used to scan the surface of the resin bonded diamond grinding wheel. The three-dimensional topography of the surface before and after the grinding was tested. The effects of laser pulse frequency and duty cycle parameters were studied. The results show that although the average scanning energy density is constant, the frequency and duty cycle affect the sharpening effect, and the influence of frequency is more significant. At the same time, the relative scoring test of aluminum workpiece and grinding wheel was used to analyze the ratio of tangential force to normal force of scoring under different scanning conditions. It is found that the ratio of tangential force to normal force can be effectively reflected by the force ratio, Cutting performance, it can be used to evaluate the sharpening effect quantitatively.
