The aim of the research is to optimize the process
parameters to attain the desired outcomes of milling the
composite materials; glass-fiber reinforced polymers (GFRP),
carbon-fiber reinforced polymers (CFRP) and Kevlar-fiber
reinforced polymers (KFRP). To enhance the surface integrity
and tool life, optimal spindle speed and feed rate for the milling
operations are determined. Using the design of experiment
techniques, number of experiments are designed, which are
replicated and randomized for the accuracy of the results. For
the milling of three types of composites, PVD coated carbide
milling inserts are mounted in a milling cutter of 16mm. Sides of
composite plates are machined (milled) in each experiment, after
which the surface roughness is measured at four different
locations using high resolution surface roughness gauge. Mean
surface roughness is determined for each sample of composite
material. It has been observed through the enhanced images of
the milling inserts that there is no crater or flank wear were
present. Whereas, chipping and damages in the coating occurred
at the higher cutting speed and feed rates on the milling inserts.
