Understanding CNC Cutting Tool Speeds Feeds

Cutting speed (SFM) SFM Also called surface speed or simply speed is the speed difference (relative velocity) between the cutting tool and the surface of the workpiece it is operating on. It is expressed in units of distance along the workpiece surface per unit of time, typically surface feet per minute (sfm) or meters per minute(m/min).
