Understanding CNC Cutting Tool Speeds & Feeds - Destiny Tool

WebTo 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 http://www.cncbasics.com/info/SurfaceFootage.pdf list of flight in nigeria
