QUALITY ASSESSMENT ON SURFACE IN A STEEL BILLET TURNING WITH HARD METAL TOOLS WITHOUT CUTTING FLUID USE

The majority of the productive processes of a certain element may be obtained by means of an optimization of a series of factors. When it has to do with the production parts or components of the technologies of the machinery ,without doubts, the characteristics and properties of the materials to be elaborated: Geometry of the tools, type of coating, parameters of cut, the use or no of cooling fluids, type of tools, machinery, a m o n g o t h e rs, influence directly over the quality of the machine surface. The development of new tools or new technologies allows the best result of the processes. This work ´s objective is to analyze the quality of the superficial finish of the machine tools in the lathe from the variation of the parameters of cut, geometry, absence of cooling fluids with the real speed of the technological calculus.
