Creep feed grinding is a high-productivity abrasive removal process that is often limited by thermal damage and high wheel wear. A review of current industrial practices in the area of coolant supply optimization in grinding shows that very little knowledge of pressure, flowrate and method of appliocation exists in industry. This paper presents an experimental procedure to evaluate the lower limit of coolant flow rate for a given grinding system consisting of a common wheel type, material type, and coolant type.
