(一)磨粒的磨削特性磨粒的圆顶近似地为多面体,其顶点(切刃)是半径为r(简称为圆顶半径)的球形体。切刃具有一定的对称面。圆顶半径为r,包容角为2ε。所以可认为磨粒圆顶的形状是球形顶点的锥体,如图1所示。在任何情况下,切刃的对称轴对参考坐标系(它包括磨粒的旋转半径及其相互垂直的两直线,其一是在磨粒的旋转平面内)的倾斜角为:η—在磨粒的旋转平面内(图1);λ—在
(1) Grinding Characteristics of Abrasive Particles The dome of an abrasive particle is approximately a polyhedron whose vertex (cutting edge) is a spherical body of radius r (abbreviated as radius of dome). Cutting edge has a certain symmetry plane. The radius of the dome is r, the inclusion angle is 2ε. Therefore, it can be considered that the shape of the abrasive dome is a cone of spherical vertices, as shown in FIG. 1. In any case, the inclination angle of the symmetry axis of the cutting edge to the reference coordinate system (which includes the radius of rotation of the abrasive grains and two straight lines perpendicular to each other, one of which is in the plane of rotation of the abrasive grain) is: η - Grain rotation plane (Figure 1); λ-in
