Pulsed cutting fluid improved machining process
Traditional machining methods are still very important in machining mechanical parts, although many non-traditional machining methods, such as electrical discharge machining, laser burning, and water jet abrasion, have been used extensively. In traditional machining processes, cutting fluid plays a very important role. It not only cools down the cutting tool and target parts, by which the cutting tool achieves a longer life and the target parts obtain better quality, but it also acts as a lubricant, decreasing the friction force between the tool rake and the machined material. In traditional machining process, cutting fluid accounts for 15–30% of the total cutting costs [Kamiya, Y., 1996. Safety and environmental control in flexible manufacturing system. Journal of mechanics and cutting tools, 40 (2), 24–30 (in Japanese)]. Although current cutting fluid provision systems work well most of the time, high productivity machining encourages use of high cutting velocity and feed rate. As a result, conventional...
