Influence of Abrasive Properties on Residual Stresses in Lapped Ferrite and Alumina

Abstract

The effect of abrasive‐particle properties on surface‐finishing residual stresses, surface finish, and material removal rates during the lapping of ferrite and aluminium oxide is quantified experimentally. It is shown that lapping with softer abrasives and smaller particles results in lower compressive residual stresses near the surface and improved surface finish. These results demonstrate possible methods for controlling surface finishing residual stresses in ceramics while at the same time achieving dimensional accuracy. Copyright © 1990, Wiley Blackwell.
