Surface Roughness after Milling of the Al/CFRP Stacks with a Diamond Tool

This study presents the results of research on the surface quality of hybrid sandwich structures after milling with a diamond blade tool. It identifies the effects of feed and machining strategy on the roughness and topography of the surface. It provides an analysis of Ra and Rz surface roughness pa...
