Cutting Tool Life Analysis in Heat Pipe Assisted Drilling Operations

Abstract

This paper further focuses on the feasibility and effectiveness of heatpipe cooling in drilling operations based on our previously related work. To achieve this, the authors used a combination of numerical analyses and experimental measurements for drilling in three different cooling conditions, i.e., dry drilling, fluid cooling, and heatpipe cooling. The evidences obtained from the experimental study and finite element analyses were compared. The results strongly demonstrate that heatpipe assisted cooling in drilling processes can effectively perform thermal management comparable to the fluid cooling used pervasively in the manufacturing industry, consequently offering the tool life extension.
