Optimization of Drilling Parameters on Alkaline Treated Jute fiber Sandwich Material

Abstract

Abstract: The present work efforts to determine CNC drilling performance and optimization of drilling parameters during drilling of treated JFRPPU-foam sandwich structures. In this drilling operation the ensuing process performance structures viz thrust, torque and delamination factor for entry and exit hole have been recognized. The effort has been made to regulate the optimal drilling parameters set. Taguchi method employed for design of experiment. The effects of parameters process such as composite geometry type, feed rate, drill speed, and drill size varied each at three different levels. In this experimentation sandwich structures L27 orthogonal array is used. A nonlinear regression model is measured and formulates the function based on the drilling parameters and fitness function. The result shows the minimization thrust force, delamination of hole drill diameter and feed rate more effect than the speed. TAN coated carbide twist drilled hole gives the result more percentage to reduce the hole wall delamination.
