Calculating spindle speeds

The lower part of the equation is PI x tool/part diameter, or 3.141 X 20. So we now know the value for the denominator is 62.82. Now our equation has known values, we can do the maths. 15000 divided by 62.82 = 241.9, let's round that up to 242. Now we know N = 242 RPM so we know what to set our spindle speed too.
