Abstract

The carbon fiber reinforced polyme composite has made a substantial impact on the manufacturing sectorsowing toits excellent mechanical, thermal and corrosion resisting properties. The surface roughness mainly depends on the machining parameters while drilling of carbon fiber reinforced polymer compositel aminates. The study concentrates on the impact of uncoated and titaniumnitride coated solid carbide drills on minimizing the roughness that is generated while making holes in bi-directional carbon fiber reinforced polymer composite by optimizing the drilling constraints[spindle speed(A),feedrate(B),pointangle(C)anddrilldiameter(D)].Experimental studies are carried out using TaguchiL27 orthogonalarray. The investigation dis closes that the drill diameter is one of the most influencing cutting parameters followed by spindle speed and feedrate.
