In a surface grinding operation, the wheel diameter = 8.0 in, wheel width = 1.0 in, wheel speed = 6000 ft/min, work speed = 40 ft/min, infeed = 0.002 in, and crossfeed = 0.20 in. The number of active grits per square inch of wheel surface = 400. Determine
(a) the average length per chip,
(b) the metal removal rate
(c) the number of chips formed per unit and the average volume per chip?
(d) If the tangential cutting force on the workpiece is 50 lb, what is the specific energy calculated for this job?
