Practical Roll Techniques
Turn the infeed slowly as the grinding wheel moves to the end of the roll. Use a scale to measure depth. If the grinder has a hand traverse wheel, this method should be used: Measure the distance the compound moves for one complete turn on the hand traverse wheel. Calculate how many turns it will take to move an inch.

How to Accurately Calculate Material Removal Rate in Roll Grinding
Material Removal Rate. Depth of cut in millimeters times feed rate in mm/s. The calculated Q prime value will be in mm 2 /sec. Ratio of volume of material removed to the grinding time (Minutes/Seconds). Better known as Q'w (Q prime). This is typically measured in cubic centimeters per minute (cm 3 /min).
