摘　　要：硬脆材料2种去除模式在工件表面分别留下塑性沟槽和脆性沟槽,对磨粒形状进行简化并使用瑞利概率密度函数表征磨粒切厚的分布,考虑二维超声振动特性对切屑厚度的影响,建立材料脆塑性去除共存的表面粗糙度模型。以氧化锆陶瓷为实验材料进行单因素实验,实验结果表明,该模型能够准确反映磨削参数和振动参数对表面粗糙的影响规律,预测误差为7.7%,具有较高的精度。The two removal modes of hard and brittle materials leave plastic grooves and brittle grooves on the surface of the workpiece respectively,simplifying the grinding grain shape and using the Rayleigh probability density function to describe the distribution of the cutting thickness of the grinding grain,considering the influence of the two-dimensional ultrasonic vibration characteristics on the cutting thickness surface roughness model for brittle plasticity removal coexistence was established.One-factor experiments were performed with zirconia ceramics as the experimental material.The experimental results show that the model can accurately reflect the influence of grinding parameters and vibration parameters on the surface roughness,and the prediction error is 7.7%,with high accuracy.
