Ultra-precision Machining

The material response during cutting can drastically change from ductile to brittle regimes with respect to the scale of deformation, temperature, pressure conditions, etc. Particularly at a nano-scale depth of cut, ductility can be the matter of the deformation size. In this topic, the transition of material removal behavior has been investigated in the machining of engineering materials. By observing material response at the atomic scale, it is aimed to formulate a machinability model in ultra-precision machining. Further, the developed model will be utilized in the development of machining strategies with improved throughput.
