Abstract
Lapping films are widely applied to the finishing processes. There are, however, a few research works on the machining characteristics of lapping films. In this study, finishing of cylindrical workpiece surfaces were carried out with measuring the grinding force, stock removal and finished surface roughness in order to examine the machining mechanism. Furthermore, the elastic contact conditions of contact roll, lapping film and workpiece were estimated by using the Finite Element Method (FEM). As a result, the effects of grinding conditions on the stock removal and finished surface roughness became clear and the behavior of grains in the contact area between lapping film and workpiece were also examined.
