A Comparative Study and Optimization of Parameters of Turning UD-GFRP in Dry, Wet and Cryogenic Condition by Using PCD Tool with Taguchi Method

Abstract

AbstractMajor applications of composites are lightweight in aerospace applications and modern fasteners for reducing the weigh purpose, in this concern composites are very difficult for machines due to non-homogeneous and anisotropic environment and it require unique cutting tools. This work is going to investigate a comparative study of various conditions like Dry condition, Wet condition, and Cryogenic condition machining (turning) of UD-GFRP composite round with Polycrystalline diamond tool in the Lathe. The responses which measure the machining quality are: the tool wear, quality of the surface, and forces generated at various stages of inputs given to the machining of UD-GFRP composite. The optimization technique, i.e., Taguchi L9 orthogonal array is used for examinations and finding out the targeted values. The design includes three independent variables at three levels, the proposed process control independent variables are: rate of feed of tool, spindle speed or velocity of cutting, and operation depth tool in the work. The investigation aims to establish the process control by studying the relationship between Dry, wet, and Cryogenic machining condition level of inputs and degree of responses to identify the optimal level of process inputs for acceptable surface quality with minimal tool wear and cutting force condition.KeywordsUD-GFRPDry wet and cryogenic machining environmentL9 Taguchi optimization technique surface roughnessPolycrystalline diamond (PCD) tool
