Spin angle is an important target of expressing ball rotation in the lapping process. Whether lapping track can uniformly cover the ball surface or not is directly determined by the variation of the angle. The simulation of spin angle track of the ball based on ADAMS (Automatic Dynamic Analysis of Mechanical Systems) with Dual Rotation Plates Lapping Method by applying virtual prototype technology and using ADAMS is given by the article. The track based on ADAMS is similar with the track of using mathematical theory on the whole. The simulation results show that DRP lapping method owns better lapping uniformity and it is easy to apply to science for the simplicity of structure and control. The spherical lapping uniformity will be further studied with ADAMS in a convenient way.
