SFM 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. SFM for high speed steel tooling), a formula can be used to determine spindle speed. Symbol Chart The drive wheel is 4" in diameter which is about foot in.

It includes a calculator to figure the spindle speed required. We also have a few handy calculators to help with some of these calculations. However, this can be automatically converted to other velocity units via the pull-down menu. N N = number of revolutions per minute.

Tip Speed - calculating tip speed based on a know blade diameter and rpm. Use this formula temperature. The RPM ( revolutions per minute ) is of the wheel, not the engine.

Change units to that of the radius.
