Research in dry machining and minimum quantity of lubricant (MQL) has intensified in recent years, operational, economic, legal, environmental and health of operators benefits, provided by these machining techniques are the factors encouraging. This work shows the influence of using three means of lubricating / cooling, dry machining, abundant gush of fluid and MQL. The machined material was steel SAE 1045. Manufacturing processes used were the turning and screwing. In turning some cutting parameters were varied, the cutting speed on three levels and advance on two levels. The number of trials was determined from the factorial experimental design considering three factors, means lubrication and coolant, cutting speed and advance per revolution. The study explored through the output variables, surface roughness, geometric deviations, wear and damage to tools and chip formation which means lubricating / cooling resulted in better machinability for steel under study. The MQL showed the best results in general, dry machining was good for the surface finish and the abundant gush of fluid brought favorable conditions for the formation of the chip. |
