Heat generation during the machining process is an important issue which can accelerate wear of tools and also affect machining accuracy and surface quality of finished workpieces. Thermal damage due to lack of cutting fluid is a severe problem in dry cutting. As a result, different cooling technologies were proposed to reduce thermal damage and prolong tool life. However, there are less studies about the development of cooling technologies for dry cutting tools. In this thesis, an overview of cooling technologies for dry cutting tools, especially the internal cooling, is mainly discussed. Two main approaches, namely heat exchanger and heat pipe, which could have more potential in cooling for dry cutting tools are summarized. A new utilization of the pulsating heat pipe which could be the future research hotspot in cooling for dry cutting tools as a result of its feature is introduced.
