Surface footage, also known as surface speed, is a measure of the speed at which the cutting tool moves across the surface of the workpiece in CNC turning. It's typically expressed in feet per minute (SFM) or meters per minute (m/min). Surface footage is a critical factor in determining tool life and surface finish. The correct surface footage balances material removal rate with the heat generated in the cutting zone. If the surface footage is too high, the tool can overheat, leading to ra....
