Abstract

This paper covers the effects of various autonomous cooling methods on the cutting performance. Heat phenomena considerably affect the wear of tools induced by finishing structural materials of low thermal conductivity. Aside from being environmentally unfriendly, conventional cooling methods sometimes fail to solve the problem. This is why this paper proposes a cooling method based on first-order phase transitions, which is successfully employed in other industries. Based on the proposed thermal cooling diagram, the researchers have designed a novel indexable cutter that combines the use of heat pipes and consumable media. It has been found out that evaporative cooling requires equipping various elements of a standard indexable cutter with porous inserts as well as special adaptations in the design of the cutting inserts. Besides, the method is not autonomous as such, as the operator must periodically replenish the coolant. According to the studies presented herein, the most preferable option is an integrated cooling system based on first-order phase transitions. This method is shown to make cutters 1.8–2.6 times more durable when finishing 110G13L steel.
