Abstract

This paper investigates deformation mechanisms and surface quality of porous carbon in diamond turning process. Experiments were performed based on L16 Taguchi method for design of experiment (DOE), and the effects of three variables including feed rate, depth of cut and cutting speed were investigated. Three types of deformation occurred in the diamond turning process, which were influenced by feed rate and depth of cut. Feed rate had dominant effect on surface roughness followed by depth of cut. By controlling the feed rate and depth of cut, surface roughness of the machined surface were controllable. There was 25% decrease in the percentage of porosity after the machining process.
