Drilling of carbon-fiber-reinforced plastic (CFRP) components in aircraft production presents many challenges. Factors including layup material, layup process, layup orientation, hole tolerance, surface finish, delamination limits, and inspection methods result in a wide range of process times. The purpose of the paper is to provide a framework to understanding the drilling process in CFRP and the resulting hole tolerance, surface finish and delamination. The paper will investigate drilled hole diameters from 3/16\mi (5 mm) up to 1\mi (25.4 mm) drilled thru CFRP/CFRP and CFRP/metallic stacks with automated drilling machines using single-sided clamping.
