Some Experimental Aspects of Grinding Soft Steel Under Different Machining Conditions

Abstract

In this study, the effects of dressing parameters, wheel topography, and machining environment on grinding performance of soft steel are investigated. To generate different grinding wheel topographies, the dressing speed and depth were varied during the dressing of vitrified Al₂O₃ wheels using a single point diamond dresser. After dressing the grinding wheels, machining tests were conducted to study the influence of the wheel topography and coolant-lubricant types on the performance of grinding operation. The results suggest that Minimum Quantity of Lubricant (MQL) is more suitable for grinding soft materials in the finishing step (shallow cut) with the finest dressing, compared to wet and dry grinding.
