This paper further focuses on the feasibility and effectiveness of heat-pipe 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 heat-pipe cooling. The evidences obtained from the experimental study and finite element analyses were compared. The results strongly demonstrate that heat-pipe 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.
