Assume that a surface-grinding operation is being carried out under the following conditions: D = 200 mm, d = 0.1 mm, 1/ = 40 m/min, and V: 2,000 m/min. These conditions are then changed to the following: D = 150 mm, d = 0.1 mm, 1/ = 30 m/min, and V = 2,500 m/min. How different is the temperature rise from the rise that occurs with the initial conditions?
