Finite Element Analysis of Optimization for Turning Parameters of Super Alloy Inconel 718
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 6
Abstract
Alloy Inconel 718, a nickel based super alloy, developed initially for use in rotating parts in aerospace and gas turbine applications, has become the preferred material for the manufacture of important Components and Auxiliary Tools and Sub-Surface Safety Valves. Super alloy Inconel 718 is mostly used in sophisticated applications due to its unique properties desired for the engineering applications. Due to its peculiar characteristics machining of Super alloy Inconel 718 is difficult and costly. The present work is an attempt to make use of Taguchi optimization technique to optimize the cutting parameters during high speed turning of Inconel 718 using Cubic Boron Nitride and Alumina Ceramic KY 1615.The cutting parameters are cutting speed, feed rate and depth of cut for turning of work piece material Super Alloy Inconel 718. In this work, the optimal parameters are cutting speed, feed rate and depth of cut. The parametric model of cutting tool and work piece assembly is done in Pro/Engineer and analysis is done in Ansys. The cutting parameters considered are Cutting Speed – 2000rpm, 3500rpm and 5500rpm, Feed Rate – 250mm/min, 500mm/min and750mm/min and Depth of Cut is0.3mm, 0.6mm and 0.9mm.It is a powerful design of experiments (DOE) tool for engineering optimization of a process. It is an important tool to find the critical parameters and predicts optimal settings for each process parameter. Taguchi method is used to study the effect of process parameters and establish correlation among the cutting speed, feed and depth of cut with respect to the machinability factor, cutting forces such as cutting force and feed force. Process used in this project is turning process. Modeling is done in Pro/E and anasis is done in ANSYS.
