摘　　要：本文用树脂结合剂金刚石砂轮对钒酸钇晶体进行了平面磨削实验,研究了砂轮线速度、工件进给速度和磨削深度对磨削力和磨削表面粗糙度的影响。结果表明:磨削力和磨削表面粗糙度都是随着砂轮线速度的增加而减小,随进给速度和磨削深度的增加而增加,其中磨削深度对磨削力影响最大,砂轮线速度对磨削表面粗糙度影响最大。钒酸钇晶体的磨削表面主要由断裂区域和光滑区域组成,当砂轮线速度为30m/s时,磨削表面存在宽度约100μm的裂痕,而随着砂轮线速度的上升,裂痕宽度降低到50μm以下,同时光滑区域所占的比例增加,这可能与发生塑性变形的机率增大有关。In this paper,the surface grinding of yttrium vanadate crystal with resin diamond wheel was carried out. The influences of grinding parameters,including wheel speed,feed rate and the depth of grinding on grinding forces and surface qualities were investigated. The results indicated that grinding forces as well as surface roughness decreased with the increase of wheel speed,but increased with the increase of feed rate and the depth of grinding. It can be found also that the depth of grinding is the main influential factor on grinding forces,and wheel speed is the primary affecting factor on the surface roughness. The ground surface of yttrium vanadate was composed of fractured region and smooth region. When the wheel speed was 30 m/s,the width of crack on the fractured region was nearly 100 μm. With the increase of grinding speed,the width of crack was reduced to 50 μm,at the same time the percentage of smooth region was increasing. This may be resulted by the increase of plastic deformation.
