A study of plane surface grinding under minimum quantity lubrication (MQL) conditions

This paper reported on the first research to conclusively demonstrate that a regime exists in shallow cut grinding where minimum quantity lubrication (MQL ~50ml/hr) offers cost and performance advantages compared with conventional fluid delivery methods (~20l/min). This pioneering work countered conventional heat-distribution arguments that opposed MQL grinding. The experimental work, validated theoretically, established requirements and boundary conditions for effective MQL delivery. Most importantly it provided the strong scientific evidence needed to support wider application in industry. Research work is continuing with Rolls-Royce to further exploit these findings in emerging processes including HEDG and vibration-assisted HEDG.
