Abstract
In this work, a performance analysis of different types of cutting fluids, commercial (mineral and vegetable based), were compared with formulations made from pure glyverine . The aim is to investigate the behavior of glycerin, after physicochemical transformation, serving as a basis for composition of cutting fluids. For this, it was analyzed the effect of each of the seven fluid studied on 1020 steel roughness after turning operation. The fluids used were water, commercial 100% vegetable, commercial 100% mineral , semi-synthetic , two bases for cutting fluid, non-commercial, made from glycerin. Three different depths of cut were used, ap = 0.5 mm ap = 1.0 mm ap = 1.5mm, in constant speed of 4,000 RPM and in a constant speed of 400 rpm, machined length l = 50mm. The initial diameter of the steel bars was ∅ = 28.00 mm and the feed rate f = 0.122 [m / min]. Turning operations were performed on a CNC Turning macgining, Romi brand, Centur 30D model. The roughness tests (Ra, Rz) were performed with cut-off = 0.80mm length l = 4,00mm, rugosimeter brand Taylor Hobson, Surtronic S128 model within the laboratory machining of the Pontifical Catholic University of Minas Gerais - PUC - MG. The results showed that the base from vegetable glycerin showed similar performance when compared to commercial fluids, in some conditions, the results were even better. This generates an indication of the possibility of using glycerin as a feedstock for the production of cutting fluids. This study indicates the possibility to formulate the glycerol with additional additives to prepare a cutting fluid. Subsequently, further studies should be conducted with this new fluid to evaluate the physical and chemical behavior on stress.
