Analysis of multipoint cutting tool temperature using FEM and CFD

Abstract

Nimonic C-263 is a British nickel-chromium-cobalt-molybdenum alloy specially meant to be used in high-temperature and high-strength applications. Consequently, it produces high thermo-mechanical loads on the machining tool when machined. As a result, excessive heat is generated during dry drilling, between Nimonic C-263 and tungsten carbide tool coated with Alcorna, which in turn reduces the durability of the tool. In order to determine the temperature distribution of the tool, the coupling of finite element machining simulations along with computational fluid dynamics simulations is performed. The temperature distribution of the tool under dry condition is simulated via the DEFORM 3D software and the Altair AcuSolve software. Further investigation under cooling condition is performed using Altair AcuSolve software. The mass flow rate of the coolants is kept constant when the temperature distribution is obtained during the CFD analysis under cooling condition. Silver nano coolant has high heat reduction compared to other coolants and is found to generate 34% less heat than dry condition.
