Feed rate per revolution
WebThis formula is used to calculate the table feed per minute (feed rate) from the feed per tooth, the number of teeth, and the spindle speed. Example: Feed per tooth (fz) = 0.2 mm/tooth Number of teeth (z) = 8 Spindle speed (n) = 600 min-1 In this case, the table feed rate is 960 mm/min. Machining Time (Tc) WebTo calculate the feed rate, use the following formula: f = N × f r (Eq. 3) where . f = calculated linear feed rate of the drill [in/min] N = spindle speed [rpm] f. r = feed per revolution of the drill [in/rev] In addition, the following rules of thumb should be observed when applicable: • Always . start with a slower speed (~50%) and build ...
