Deterministic modelling and simulations of the internal cooling of end mills

摘要

About 80% of the energy used for material cutting transforms into heat at the cutting zone. This affects the mechanical properties of the cutting tool, resulting in accelerated tool wear and tool failure. Due to the increasing focus on sustainable and environmentally friendly machining, efforts to reduce these temperatures have focused on the indirect cooling of the tool. This paper proposes a mathematical description for a rotating end mill with internal cooling. The mathematical model is supported with Computational Fluid Dynamic (CFD) simulations and indicate that up to 65 percent temperature decrease at the tool tip can be by using internal cooling.
