The following conditions and settings are used in a certain surface grinding operation: wheel diameter = 6.0 in, in feed = 0.003 in, wheel speed = 4750 ft/min, work speed = 50 ft/min, and cross feed = 0.20 in. The number of active grits per square inch of wheel surface = 500. Determine

(a) average length per chip,

(b) metal removal rate, and

(c) number of chips formed per unit time for the portion of the operation when the wheel is engaged in the work.
