 Surface feet per minute

Surface Feet Per Minute (SFPM or SFM) is a measurement commonly used in manufacturing and machining to indicate the speed at which the surface of a rotating tool or workpiece moves. It's expressed in feet per minute and helps determine the speed at which a cutting tool should operate for optimal performance. In machining applications, SFM is critical because it impacts the quality of the cut, the tool wear, and the overall efficiency of the machining process.
