Abstract

Titanium alloys are considered as one of the best engineering metals due to their high strength to weight ratio and excellent mechanical properties. In spite of that, Titanium alloys are materials of poor machinability meaning they are very difficult to cut. The objective of this project is to identify the optimum cutting parameters used in milling of Titanium alloy for better results in terms of the cutting forces and surface roughness. Machining parameters such as cutting speed, feed and depth of cut and type of coolant used are considered in this work. The design of experiment is done using Taguchi method. The results which include the surface quality, cutting forces and tool wear will be investigated in the experiment.
