    Abstract :

    Abstract: Machining of GFRP laminate materials are difficult task due to their anisotropic and non homogeneity in nature which consist of distinctly different phases. Machining of composite materials is rarely avoided in view of losing the strength of components due to fiber breakage and other damages. In specific situations where metal inserts are inevitable in case of joining or affixing with some other mating part, the need for high quality machining arises with minimal damage to the laminated structure. In this connection precision machining is needed the present research work deals with milling. The machining has become an important issue which needs to be investigated in detail and experimentations performed with various machining process parameters are carefully analyzed with the mill tool dynamometer, talysurf and travelling microscope so the analysis and results work were correlated by graphs. For finding the best optimal parametric combinations are very important aspect in order to minimize damages of machined parts and increasing the productivity. For this reason, different levels of factors like cutting speed, feed, and depth of cut, fiber orientation angle, fiber volume fraction, tool rake angle and tool clearance angle are chosen carefully to obtain optimum output values. This investigation is based on Taguchi’s L27 orthogonal array was established and Analysis of variance (ANOVA) has been utilized explore the effect of input factors on surface roughness (Ra), cutting force (F) and delamination factor (Fd) are studied and performance evaluated by different tool nomenclature solid mill cutters. The correlation was obtained by multiple variable linear regressions using Minitab15 software.
