摘　　要：基于裂纹扩展效应的平面碳化硅陶瓷切槽-推磨复合式加工技术是一种新型低成本、高效率的平面陶瓷加工技术,切槽加工是该技术的第一道工序。通过开展正交试验,重点研究了砂轮转速n、进给速度、切削深度对单颗粒平均磨削力的影响。在传统磨削力经验公式的基础上,在Eviwes8.0中用最小二乘法进行三元线性回归分析,建立了金刚石砂轮深切削缓进给碳化硅陶瓷磨削力模型,为上述工序提供了加工参数优选依据。A new technique which called cutting and axial pushing-grinding process based on crack propagation of plane Silicon Carbide（ SiC） is a kind of low cost,high efficiency processing on plane ceramics. Cutting process was its first step. By carrying out the orthogonal experiment,the research of influence law how three processing parameters such as grinding wheel speed n,pushing-grinding velocity,pushing-grinding depth,affect single particle average grinding force was laid special stress on. On the basis of the traditional empirical formula of grinding force,ternary linear regression analysis was carried out with the least square method（ LSM） in Eviwes8. 0,then establishing diamond wheel deeply cutting and slowly feeding ceramic average grinding force model,which provides a processing parameter optimization for the above process.
