It is assumed that abrasive grain is charactered by grit designation and structural number of an abrasive tool and it is cone shape with spherical tip, the distribution of the abrasive grain protrusion heights of the abrasive tool is Gaussian distribution and the nominal contact between the polishing tool and the wheel surface is of elliptical Hertzian contact, the actual contact pressure is proportional to the nominal pressure.A theoretical equation of MRD which is orthogonal to the tool path was derived and its solution process was introduced. MRD was involved with abrasive grain, normal polishing force, feed rate, the tangent relative velocity between polishing tool and wheel, and relative principal curvature. The experimental results agree well with the model，which verifies the theoretical model.
