Abstract

In this paper, the feasibility and effectiveness of heat pipe cooling in end milling operations is investigated. A new embedded heat pipe technology was used to remove the heat generated at the tool-interface in the end milling process. Numerical studies were involved in four cases, including solid end-mill, solid end-mill with coolant, heat pipe end-mill and heat pipe end-mill with coolant. The thermal, static and dynamic characteristics of the end-mill were investigated using a numerical calculation with Fast Finite Element (FFE) plus solvers based on explicit finite element analysis software. The results indicate the heat pipe end-mill is most feasible and effective in the actual end milling processes.
