Optimization of Burr Height and Surface Roughness in the drilling of PU based babbar fibres reinforced composites using Taguchi Method

Abstract

Now a days, composites are replacing a large number of metallic parts, because of advantages like light weight, low cost and their comparable strength. List of their applications in the industry is very long and it is still has a growing potential. During mechanical machining these composites undergoes many operations. Drilling and milling are among the common operations applied to them. This study presents the use of Taguchi Method to optimize the process parameters for minimizing burr height and surface roughness in the drilling of Polyurethane based randomly distributed babbar reinforced composites. Cutting speed, feed rate and tool angle each having three levels, were selected as control parameters and a plan of experiments based on L27 OA was performed drilling. ANOVA statistical tool and mean vs control factor were used to analyze the data obtained from the experiments.
