Thermal Design and Analysis of an Internally Cooled Smart Cutting Tool and its Implementation Perspectives

Abstract:

In this paper, finite element thermal analysis and experimental study were performed to verify the design concept and thermal management of a smart cutting tool with internal cooling. The main idea is to build micro cooling channel within the tool and located close to the cutting tip, forming a closed-loop of the internal cooling circuitry. The cooling lubricant contamination will be avoided and the cutting temperature be reduced when cooling fluid flows through the closed channel. The cutting temperature at the tool tip can be estimated by measuring the cooling fluids temperature at the inlet and outlet of the cooling structure. Thermal modeling based on FEA-CFD is carried out by using ANSYS and FLUENT. The simulation results demonstrate that the innovative tooling design concept can effectively reduce tool temperature away from the extremely high temperature and sensing the cutting temperature at tool tip. Preliminary experiments have further proved the concept of the tool system.
