Abstract
Due to the industrial competition to product fabrication with a low cost and low time, more and more, the environment has been degraded, not only by natural resources extracting, but also by the polluting means. As a way to alleviate this problem, the governments have been created laws compelling the industries to work in a search for less harmful solutions to the environment through “green methods”. On the research side, several works are been carried out proposing techniques that minimize the pollution problem caused by industries today. In this work, a study about roughness regarding an alternative technology is proposed. This technology is based on tools cooled internally modified by channels insertion where a coolant fluid circulates, cooling it during the machining process. The proposed cooling system has a main objective to exclude or minimize the cooling fluid application, which is one of the main factors in machining pollution. This work proposes to analyze the influence of this system on the roughness of the piece comparing with dry cut. To check this effect, turning tests were performed on cast gray iron where the cutting speed parameter was varying in three levels, maintaining the feed and depth of cut constants. As a result, it was noticed that the use of cooled tools does not influence significantly in roughness.
