Abstract:
In general, cutting fluids are widely used in cutting to reduce tool wear and maintain machining accuracy. However, wet cutting using cutting fluids causes deterioration of the work environment and negative effects on the natural environment. Thus, it is desirable to develop cutting technologies without using cutting fluids. On the other hand, in dry cutting with no cutting fluids, tool wear is significantly increased due to the high-temperature rise at the cutting point. In this case, it is indispensable to provide optimum cooling structures to the tool holder. For the above reasons, our study proposed a tool holder with internal cooling structure and external cooling structure for cutting tool cooling. In the proposed tool holder design, it is expected that high cooling performance for the cutting tool. In this paper, the fundamental characteristics of the proposed tool holder that has internal and external cooling structures are investigated via simulation studies. Specifically, this report verified the thermal characteristics of the proposed tool holder.
