Investigation of non-edible vegetable oil as cutting fluid in boring operation using MQL technique for CEW-1 steel

Abstract

The cutting fluid plays a significant role by cooling the machining region and evacuating chips from the cutting area during the machining. However, using the traditional cooling approach has a negative impact on human health and the environment. Furthermore, it contributes for 18 to 20 % of the entire production cost in the manufacturing industry. To address this problem, minimum quantity lubrication (MQL) is outperforming traditional cooling method in terms of achieving a high-quality surface and better overall machining performance. In this study a number of trials has been taken to investigate the effect of process parameters on surface finish, circularity, cylindricity. The trials have been carried out on boing machine. Comparative study by using Neem oil, Karanja oil and convectional oil in boring operation by using MQL technique has been carried out. Comparative results encourage using MQL system along with Neem and Karanja oil in boring operation of CEW-1 steel. Although kaanja oil and conventional cutting fluids perform similarly, Neem oil outperforms during boring of “CEW 1” Grade Steel. Also it has been observed from experimental results that minimum quantity lubrication method performed better as compare to conventional flood system.
