This report describes an analysis of the steel ball lapping process by use of lap plates with V-shape grooves. An evaluation of three-dimensional sphericity in terms of spherical functions enables quantitative analysis of this process. The angle of the contact points between the steel ball and the lap plays an important role in this process because the interference value between the ball and the lap is related to this angle. The rate of sphericity improvement is strongly dependent on the contacting point angle. Experimental results show that the contacting point angle increases with increasing wear of lap. This increase in the angle increases the rate of sphericity improvement in second-order waviness, and decreases that in third-order waviness, which are included in the form error. Furthermore, the rate is also related to the total number of balls processed at one time.
