Actually, machining without cutting fluid is one of the most discussed topics of the metal-mechanical industry. The high cost of fluids, ecological problems in the work environment and the destination of wastes, as well the health of workers, have encouraged the removal or restriction of the use of cutting fluids. The research of the drilling process seeks to adapt cutting conditions and circumstances to perform machining without cutting fluid. Thus, this paper reports a study of the lack’s effects of cutting fluids in high-speed-steel tools HSS M2, in machining of steel AISI P20. For the development of tests were used twist drills DIN 338, with two edges, uncoated. The drills had mainly the mechanisms of abrasion and adhesion. The absence of the cutting fluid became the process quite severe, subjecting the tools to high thermal solicitations.
Key words: drilling, dry machining, wear mechanisms.Downloads
