Now-a day’s composite materials plays vital role in the manufacturing industries. Composite material
like Glass Fibre Reinforced Plastics plays an important role in applications as an alternative to various heavy exotic
materials. GFRP is used in aviation, automobile and other industries due to their advantages over the conventional
materials. Main problem associated with the GFRP material in milling process is due to its heterogeneity and surface
delamination during machining affects uniqueness of the material and the machining parameters. In this research work
the GFRP composite is experimentally investigated by CNC milling process with various input parameter like depth of
cut, spindle speed, feed rate. The effect of process parameters on the dimensional accuracy, surface accuracy, surface
finish and damages of the slots produced by end milling on GFRP composite. Experiments were conducted based on the
established Taguchi's technique L27 orthogonal array and ANOVA. The performance of various parameters are
evaluated by measuring the delamination factor and surface roughness.
