Title 

Cryogenic Machining of Advanced Engineering Materials

Abstract

Advanced Engineering Materials such as Ti and Ni based alloy have become increasingly important and have been widely used in various industries such as aerospace, and biomedical for producing the functional components. Machining processes as conventional material processing methods continue to play a significant and dominant role in product manufacturing with growing market share among all other manufacturing processes as the requirement for machined products in aerospace and biomedical industries continues to grow at a rapid pace. The process of cryogenic machining, due to increased demand for environmentally friendly manufacturing processes and its effective cooling capability during cutting of advanced engineering materials, has seen a growing interest in the machining community. Furthermore, recent studies demonstrated that cryogenic cooling has also substantial effect on functional performance of components by remarkably altering the surface and subsurface aspects of these components. 

In this talk, cryogenic machining process of advanced engineering materials including near- beta titanium alloy, high temperature shape memory alloys will be presented by focusing on its contribution to process performance measures such as tool life, cutting temperature, forces components, frictional conditions, etc. The talk will also include the effect of cryogenic cooling on surface integrity aspects including microstructure, microhardness variation, phase transformation, wear resistance of machined advanced engineering materials. Finally, finite element modeling of chip formation process under cryogenic cooling conditions will be presented.
