Determination of Optimum Parameter Levels for Quality Characteristics in Conventional Drilling of Thick Polymeric Composites

Article Preview

Abstract:

Since literature on the machinability of non laminated composites is scarce, an investigation was extended away to study the machinability of thick non laminated Glass Fiber Reinforced Plastic (GFRP) composites and to compare the above with machinability of thick laminated composites. The composites with high fiber weight fraction were drilled with a special geometry coated carbide drill (Ratio drill). Taguchi’s orthogonal array and analysis of variance (ANOVA) were used to examine the influence of process parameters (feed and spindle speed) on quality characteristics (thrust force and torque). The optimum degree of process parameters towards aperture quality was obtained.
