The Emergence of MQL with vegetable oil as a green manufacturing technique: A Review

Abstract

For every manufacturing industry, product rejection is not tolerable. Productivity suffers because of rejection, material cost, and labor cost increases. Cutting fluids are used to protect the tool and work-piecework-piece from the damaging effects of high temperatures and poor surface finishes. Cutting fluids are used as lubricating and cooling agents. Due to cost constraints, most small-scale industries in developing nations employ conventional flood lubrication systems, resulting in increased exposure to dangerous chemicals and environmental issues. As a result of increased health concerns and rigorous government regulations, innovative methods to decrease or remove harmful cutting fluid have been developed. In this review paper, three approaches are considered while surveying the literature. Hazardous effects of the cutting fluids; comparison of dry, flood, and MQL cutting; and performance of the cutting fluids prepared using vegetable oil. It is found that vegetable oil with minimum quantity lubrication under different machining conditions gives better performance and reduces health hazards.
