The use of carbon fiber reinforced polymer (CFRP) composites in manufacturing of automotive, marine, sport, chemical
and biological equipment is gradually increasing as well as aerospace industry. Especially, the need for drilling of these
materials in tolerance of low roughness and suitable roundness because of requirement to high strength in assembly parts
is an important safety problem for aerospace industry. The hole surface integrity and delamination occurred in drilling of
the CFRP materials, which change depending on their characteristics properties which are anisotropy, heterogeneity and
laminated structure, and so affect the hole quality. Also, the thermomechanical responses (e.g., cutting force, cutting
temperature, chip formation) changing according to cutting conditions such as tool geometry, cutting speed and feed rate
are negatively affect the machinability of the CFRP. For these reasons, the selection of drill geometry and drilling
parameters has high importance due to in drilling of carbon fiber reinforced polymer which has anisotropy, heterogeneity
and laminated structure. This study focused on the effects of drilling parameters on the hole quality in drilling of carbon
fiber reinforced polymer composites by applying constant and varying feed rate with uncoated tungsten carbide.
