Abstract
The increasing competition between companies in the world market makes the same seek processes that ensure lower costs allies to high productivity and high quality product. Thus the great industrial and technological development has increased the search for machining processes that promote, for example, great capacity of chip removal, reduction of damage and tool wear and minor impacts to the environment. Regarding nickel alloys, they have an extremely important role in the automotive and aeronautics industry among others. The nickel super alloy studied is the Pyromet A31for having mechanical strength and corrosion resistance at temperatures of approximately 815 °C, for both two conditions of the alloy were used hot rolled and hot rolled followed solubilization. The objective of this work is to study the influence of the application of cutting fluids in turning, and thus promote the optimization of machining this super alloy. The super alloy was turned using various machining parameters: cutting speed, feed rate, depth of cut, Minimum Quantity Lubrication (MQL), Flood Fluid, cutting tools with coating and without coating. After turning chip samples were obtained, was measured roughness of the material, volume of removed chip, cutting length and held macrostructural analyzes and of lifetime of the tools used in order to detect possible wear. In this work it can be seen that in general the application of coating cutting tools present greater cutting lengths when compared to without coating. Regarding the use of MQL noted that despite of ecologically correct not promote cutting lengths sufficient to viable its application, however when it is necessary lower values of roughness the MQL showed efficient.
