AB  - The application of composite materials is extensively used in automotive and aerospace industries
due to their high strength and light weight. Adversely, machining of such material is extremely challenging
because of its inhomogeneous nature, anisotropic and abrasive characteristic. Service life and performance of
a component is highly dependent on the quality of machined surface produced. An experimental investigation
is conducted to determine the effect of the cutting parameter: Spindle speed (N) feed rate (f<sub>r</sub>) and depth of cut (d<sub>c</sub>) on the surface of a machined CFRP/Al2024 hybrid composite material. Machining operation used is edge
trimming using Kennametal burr tool of 6 mm diameter and the machining method is up milling. The aim of the
experiment is to set optimum cutting parameters for obtaining quality machined surface. Surface quality was
quantified based on surface roughness. Result showed that spindle speed is the most significant effect on
surface finish followed by feed rate and depth of cut. The best surface finish between 1-2 &#956;m can be obtained
by the combination of N = 2330 rpm, f<sub>r</sub> = 500 mm/min and d<sub>c</sub> = 0.01 mm. The validation test showed average deviation of predicted to actual value of surface roughness is 6.8% for Al 2024 and 7.25% for CFRP.
