12 x SFM. 3.14 x Diameter. =. RPM=. 12 x 100 (ft/min) =764 (revs/min -1) 3.14 x 0.5 (in) For turning applications we do not need this formula since Spindle Speed is usually given in Constant Surface Speed (CSS), which uses SFM value directly. But if you still want to use RPM formula, then diameter value is the actual diameter of work piece.

RPM: (Revolution per minute) The number of times the tool or stock rotates 360° during a 1 minute time interval. SFM: (Surface feet per minute) The distance traveled in feet per minute by a cutting edge during a 1 minute period. The value is a combination of the material the cutting tool is made of and the material to be machined.

The end mill speed is calculated with the following formula: n [rpm] = (vc [m/min] *1000) / 3.14 * ø d1 [mm]) Example calculation: vc = 500 m/min (selected from chart) d = ø 8 mm 19904 rpm = (500 *1000) / (3.14 * 8). If the maximum speed of the milling motor is lower than the calculated value, the maximum speed of the milling motor needs to be inserted into the formula for the feed calculation.
