WebSFM is a combination of diameter and the velocity ( RPM) of the material measured in feet-per-minute as the spindle of a milling machine or lathe. 1 SFM equals 0.00508 m/s (meter per second, the SI unit of speed). The faster the spindle turns, and/or the larger the diameter, the higher the SFM. WebSince we already know from the first example that the suggested RPM is 6,112 all we need is the chip load per tooth. The manufacturer suggests .005” per tooth chip load on this tool, so we have all of the information we need to calculate our feed rate. Machine shop math inches per minute formula. See? That is not as confusing as it looked.
