SFM to RPM [ Easy Guide to Surface Speed / SFM in Machining ]
SFM Formula (SFM to RPM Formula) Once you've got a suggested surface speed, it's relatively easy to convert it to spindle rpms. The simple machining formula you'll use is: Spindle RPM = SFM / circumference. Where the circumference is that of the workpiece on a lathe or the cutter on a mill. Given that simple formula, now you know why ...
