Experimental Investigation To Optimize Process Parameters In Drilling Operation For Composite Material

Abstract

In this thesis, the input parameters considered are point angle, tool diameter, spindle speed, feed rate and depth of cut. Different combinations of the above parameters are considered to get the maximum material removal rates using L12 orthogonal array in Taguchi method. The parameters are drilling diameter of cutting tool - 6mm, 10mm, point angle - 118⁰ & 120⁰, Speed – 800rpm, 1200rpm, Feed Rate – 30mm/min, 50mm/min and depth of cut – 0.5mm, 1mm. Theoretical calculations are done to calculate thrust force and torque. The assembly of work piece and tool is modeled in Creo 2.0. Structural analysis is done on the assembly to verify the stresses for different materials Mild Steel, Aluminum alloy and Glass fiber epoxy composites. Analysis is done in Ansys.
