摘要： 快速点磨削主要用于轴类零件表面的加工,但由于砂轮存在点磨削变量角度,加工表面纹理特征不同于常规外圆磨削.通过点磨削几何学分析,建立了点磨削纹理方向计算模型,分析了点磨削纹理特征及影响因素.根据外圆磨削试验加工工件表面的实际测量数值与点磨削纹理特征的模拟结果,分析了纹理方向对表面粗糙度评定参数及摩擦学特性的影响.结果表明,不同纹理方向的工件表面粗糙度评定参数不同,在垂直于运动速度方向的剖面内,对于表面粗糙度数值存在最优纹理方向角.

Abstract: The quick-point grinding is mainly used to process shafts. The characteristics of the surface texture are different from that of the general cylindrical grinding for the reason that there is a variable of point grinding angle. Based on the analysis of the geometry of point grinding, the calculation model of the point grinding texture direction is built, and the characteristics of the point grinding texture and its influencing factors are explored. Moreover, this paper analyzed the effects of the texture direction on the evaluation parameters of the surface roughness and the tribology characteristics in terms of the measured value of the work processed by cylindrical grinding and simulation results of the point grinding texture characteristics. The results show that the works with different texture directions have different evaluation parameters of the surface roughness. There is an optimal texture direction angle for the surface roughness in the profile perpendicular to the moving direction.
