Abstract High quality surface milling of Fibre reinforced Plastic (FRP) materials present variety of issues, such milling is one of the foremost oftentimes used material removal processes in machining of FRPs to produce a well-defined surface and has surface delamination related to the characteristics of the material and therefore the cutting parameters used. The surface quality and dimensional precision greatly have an effect on the elements throughout their useful life, especially in cases wherever the elements come in contact with different elements or materials. Optimization of machining parameters is an necessary step in machining. This project presents a new approach for optimizing the machining parameters on end milling of glass-fibre reinforced plastic (GFRP) composites. Optimization of machining parameters was done by Taguchi’s L27 orthogonal array and milling experiments were conducted for GFRP composite plates using solid carbide end mills with various helix angles. The parameters of machining such as, spindle speed, feed rate and helix angle are optimized by multi-response concerns particularly surface roughness and delamination factor. Based on mean effective plots, the optimum levels of parameters have been investigated and significant contribution of parameters is determined by analysis of variance.
