摘要：与传统磨削技术相比，激光结构化金刚石砂轮能有效降低磨削力和磨削温度。但目前结构化砂轮技术仍存在磨粒磨损与沟槽边缘磨损严重的问题。针对此问题，借鉴斜截面技术，通过脉冲激光在金刚石砂轮表面烧蚀，制备出直角沟槽金刚石砂轮和梯形沟槽金刚石砂轮，进而进行普通砂轮与两种结构化砂轮的对比磨削试验。结果表明：磨削力会随磨削深度的增大而升高，但梯形沟槽金刚石砂轮能有效降低磨削力；同时，梯形沟槽金刚石砂轮未结构化区域的磨粒磨损和沟槽边缘区域的磨损大幅度降低。

Abstract:Compared with traditional grinding technology，laser structured diamond grinding wheel can effectively reduce grinding force，grinding temperature and subsurface damage.However，at present，the structural grinding wheel technology still has the serious problem of groove edge wear.In order to solve this problem，using the oblique section technology for reference，the rectangular groove diamond grinding wheel and the trapezoidal groove diamond grinding wheel are prepared by pulsed laser ablation on the surface of the diamond grinding wheel，and then the grinding experiments between the common grinding wheel and two kinds of structured grinding wheels are carried out.The results show that the grinding force increases with the increase of grinding depth，but the trapezoidal groove diamond wheel can effectively reduce the grinding force.At the same time，the abrasive wear of trapezoidal groove diamond grinding wheel in the unstructured area and the wear of groove edge area are greatly reduced.
