The arc of contact in grinding is the portion of the circumference of the grinding wheel that is in contact with the workpiece. According to Foster, the longer the arc of contact, the more critical wetting becomes. "The correct velocity also is very important. A lot of people will flood the grinding area, but this is actually not beneficial.
