Improving the Quality of Surfaces Finished by Lapping by Robust Parameter Design

Obtaining special quality surfaces as well as higher dimensional and geometrical precision entails deployment of surface smoothing processes, one of which is lapping. A lapping process is strongly influenced by a number of input parameters, the most important ones being machining speed, pressure, duration of lap plate – abrasive paste – workpiece contact, kinematics of the machine-tool etc. The paper presents a study on the influence of machining speed in lapping on the roughness of metal surfaces.
