Process Parameter Optimization for Turning Operation of Titanium Alloy (Ti6Al4V) Using Fuzzy Logic Methodology

M. Gomathi Prabha, Aravind Babu R

Abstract


Titanium alloys are known as difficult-to-machine materials mainly due to low thermal conductivity leading to “high reactivity with cutting tools” causing poor tool life. This paper aims to optimize process parameters for machining Ti6Al4V in order to increase tool life and to obtain good surface finish. Experiments were conducted based on central composite design and a quadratic regression model has been developed. The relationship between input parameters (speed, feed rate, depth of cut) and output parameters (tool life and surface roughness) were studied. Experiments were carried out using conventional lathe machine TurnMaster40. The process parameters were optimized for better tool life and surface finish using Fuzzy Logic methodology.

Keywords: comprehensive output measures (COM), fuzzy logic approach, surface roughness, tool life
