(SI units) Wheel diameter = 160 mm, and infeed = 0.03 mm in a surface grinding operation. Wheel speed = 1500 m/min, work speed = 0.25 m/s, and crossfeed = 4mm. The number of active grits per area of wheel surface = 35 grits/cm.
When the wheel is engaged in the work, determine:
a. Average length per chip,
b. Metal removal rate,
c. Number of chips formed per unit time for the portion of the operation.
