mill speed calculation formula

• Understanding CNC Cutting Tool Speeds Feeds

To find approximate RPM the old machinists would follow the formula RPM= CSx4 /D which is essentially the same as what we use today RPM = SFM X 3.82 ÷ Tool Diameter just without the division The SCS SFM is the cutting speed in feet per minute 4 is a constant and D is the diameter of the cutter So simply put Multiply the SFM by 4
