Study of Hole Cylindricity and Surface Roughness in Drilling Application on Aircraft Wings

Abstract

This study aimed to determine the effect of drilling parameters on hole cylindricity and surface roughness in drilling applications on aircraft wings. It was determined that increasing feed rate resulted in poor hole cylindricity and surface roughness. The ideal feed rate for better hole cylindricity is 0.230 mm/rev, while the ideal feed rate for better surface roughness is 0.200 mm/rev. Both hole cylindricity and surface roughness have a minimum correlation with each other in producing a good quality of drilled holes.
