Abstract: The use of cutting fluid in milling operations is controversial. The increase of temperature variation already present in milling makes the presence of cutting fluid with high cooling capacity, usually deleterious to the tool life. However, the tool wear mechanisms of milling cutters with and without cutting fluid are not well established. This paper verifies the performance of the finish milling operation of the martensitic precipitation hardened stainless steel under two cooling/lubrication conditions, two cemented carbide grades and two cutting speeds. The wear mechanisms were verified using a Scanning Electronic Microscope (SEM) and EDS analysis. The results demonstrated that the tool life obtained in dry cutting is much longer than that obtained when a flood of abundant emulsion is used and also that the tool wear mechanism changes when dry cutting is replaced by the cutting with abundant emulsion.
