Now choose the right surface feet per minute (SFM) or surface meters per minute (SMM) Use the SFM and the diameter of the mill to calculate the RPM of your machine. Use the RPM, IPT, CLF and the number of flutes to calculate the feed rate or IPM. If you want to be conservative, choose a slightly lower SFM, but always choose the recommended FPT.

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 small diameter tools such as drill bits have to be spun faster than larger diameter tools. Their circumference is smaller, so the rpm goes up.
