Formula for feed rate
WebFeed rate in thread turning—Equals to the pitch or lead (for multi-start threads) of thread (usually 0.5 or 1.0mm/rev). Feed rate in drilling—Must be very low otherwise tool may break due to chip clogging. Typical value is … WebFeed (f) = 0.2 mm/rev Spindle speed (n) = 1100 min -1 Length of workpiece (lm) = 120 mm First, the machined length per minute is calculated, in this case from the rotational speed …
