FEM based evaluation of Ti6Al4V cutting with plain and textured WC/Co tools under cryogenic cooling environment

The present work investigates the effect of cryogenic coolant on machining of Ti6Al4V alloy with plain and laser textured carbide cutting tools. The textured tools were used for machining under dry and cryogenic cutting conditions, and the machining results were compared with plain tools. Cutting forces, average tool temperature, interface temperature, and tool wear were predicted with the help of FE simulations. Results show a reduction in average cutting temperature for textured tools under cryogenic conditions. FEM simulations predicted the microscopic wear inside and around the textures and nearly 50% reduction in microscopic wear has been obtained for textured tools under cryogenic cooling.
