Question: A grinding operation is taking place with a 10-in. grinding wheel at a spindle rotational speed of 4000 rpm. The workpiece feed rate is 50

A grinding operation is taking place with a 10-in. grinding wheel at a spindle rotational speed of 4000 rpm. The workpiece feed rate is 50 ft/min and the depth of cut is 0.002 in. Contact thermometers record an approximate maximum temperature of 1800°F. If the workpiece is steel, what is the temperature if the spindle speed is increased to 5000 rpm? What if it is increased to 10,000 rpm?
