- Abstract
Since the beginning of this century manufacturing processes have been systematically and scientifically developed and analyzed to achieve, through a measure of innovation, a maximum efficiency in association with economic manufacturing conditions, hi addition to pollution and environmental issues, the industries also reasonably insist economic viability through technological benefits in terms of product quality, tool life and saving power consumption. This work presents the results and analysis of cutting fluid performance in turning operations, discussing to what extent the proposed bio-based coolants perform in comparison with conventional coolants. Cutting fluid performance was evaluated with respect to tool life aspects such as tool tip temperature, cutting forces and product quality in terms of surface roughness. Two ferrous materials IS2062 steel and EN8 alloy steel are used in turning experiments with high speed steel (HSS) and uncoated throwaway tungstun carbide (WC) inserts as cutting tools. Two groups of cutting fluids were tested that is, four bio-based coolants and four conventional coolants. The bio-based coolants included mahua oil (Madhuca Longifolia), honge oil (Pongamia Pinnata), gingelly oil (Sesame oil) and cotton seed oil. The conventional coolants included mineral oil, commercial vegetable oil, synthetic fluid and distilled water. Initial results indicate that the performance of bio-based coolants is better than or equal to the conventional coolants.
