The study of cutting fluid performance in turning is of great importance because its optimization characteristics has associated benefits such as improved tool life and overall quality of machined components as well as reduction in power consumption during machining. However, there are recent concerns with the use of cutting fluids from the environmental and health standpoints. Since environmental legislation has become more rigorous, the option for “green machining” attracts the interest of several manufacturing companies. It is important to consider the cost of machining which is associated with tool wear, depending on the cutting environment. The use of vegetable oil may be an interesting alternative to minimize the health and environmental problems associated with cutting fluids without compromising machining performance. This paper presents a comparative study of mineral and vegetable cutting fluids in terms of tool wear after turning SAE 1050 steel grade with cemented carbide cutting tools. Constant depth of cut of 2mm and variable cutting speed (200 and 350 m/min) and feed rate (0.20 and 0.32 mm/rev) were employed. Test results suggest that is possible to achieve improvement in machinability of the material and increase tool life by using vegetable cutting fluid during machining. Tool life increased by about 85% when machining with vegetable-based fluids compared to mineral-based fluids. Analysis of the worn tools, however, revealed a more uniform wear on the worn flank face when machining with mineral-based fluids.
