Subtractive Manufacturing (Machining)
This research aimed at understanding and developing computational modes for subtractive manufacturing, i.e. material removal through cutting. Work has been focussed on different materials, for example surface defect machining of silicon by considering the high-pressure phase transformation (HPPT). Other works involved machining of nickel based super alloys to understand the residual stress relaxation of the forged and quenched components.
