This thesis presents the design, simulation-based evaluation, and parametric analysis of a turning tool with an integrated internal liquid nitrogen (LN2) cooling chamber for cryogenic machining applications. The primary objective is to provide a foundational design concept and demonstrate structural stability for the tool, which features an integrated cooling chamber, to guide the future development of an internally cooled cutting tool. Simulation variants were designed by design of experiment using CCD full factorial RSM. A structured DOE incorporates three continuous factors (heat transfer coefficient, tip temperature, and atmospheric temperature), and two categorical factors (insulation method and chamber size). 80 simulation matrices were developed and analysed under steady state thermal analysis, and the resulting temperature loads are applied as a boundary condition in structural analysis, which also considered machining forces representative of hard turning.
