Simply enter the values and click "Calculate". So let's restate the speed in units of feet/minute: (10 mph x 5280 feet/mile) / 60 min/hr = 880 feet/min. The Turning Speed and Feed Calculator is a great tool to calculate spindle speed and feed rate for turning operations, as well as the cut time expressed in minutes. Speed of Driver Gear (n1) = 100 rpm Notice that the diameter of the large roll is 6 times the diameter of the first roll and the surface speed is 6 times that of the first roll. The required rotational speed is determined from the cutting speed V in metres per minute [m/min] or in metres per second [m/s] and the diameter of the tool d x π (3.14). Custom designed parts for street rod and other makes. for a 3/16 inch diameter, two-flute end mill with a cutting speed 200 SFPM and estion 13 Calculate the pitch diameter for a 48 tooth gear that has a diametral pitch P-20. Machining Calculators - Cutting Speed and Spindle Speed Machining Calculators should be used to calculate what speeds you should be machining your parts at, by taking the material, tool and tool material into account.
