为了提高键合去除的效率和均匀性，建立了多脉冲激光烧蚀的有限元模型，并进行了激光烧蚀和锐化的工艺试验。结果表明，随着激光功率密度的增加，键合去除效率呈线性增加。增加光斑重叠率可以提高键合去除效率，而改变线重叠率对键合去除效率几乎没有影响。提高光斑重叠率和线重叠率有利于提高键合去除的均匀性，保证晶粒凸起高度的均匀性。所建立的有限元模型可为激光刃磨砂轮（不限于青铜结合剂金刚石砂轮）时工艺参数窗口的确定和表面形貌的预测提供理论依据和数据参考，从而节约成本，提高效率。
In order to improve the efficiency and uniformity of bond removal, a finite element model of multi-pulse laser ablation was established, and process experiments of laser ablation and sharpening were carried out in this paper. The results show that the efficiency of bond removal increased linearly with the increase of laser power density. Increasing the spot overlap ratio could improve the efficiency of bond removal, and changing the line overlap ratio had almost no effect on the efficiency of bond removal. Increasing the spot overlap ratio and the line overlap ratio was beneficial to improve the uniformity of the bond removal and ensure the uniformity of the grain protrusion height. The established finite element model could provide theoretical basis and data reference for determining the process parameter window and predicting the surface topography when performing the laser sharpening of grinding wheel (not limited to the bronze-bonded diamond grinding wheel), thereby saving cost and improving efficiency.
