No responsibility from Kennametal is assumed. Metric Inch. WebWith a milling machine or jointer, where multi-tipped/multi-fluted cutting tools are involved, then the desired feed rate becomes dependent on the number of teeth on the cutter, as well as the desired amount of material per tooth to cut (expressed as chip load). WebNext, calculate the feed rate used for plunging. Remember annular cutters should be fed at approximately 25% of the feedrate for an equivalent sized endmill. From Table 3, lookup the recommended feed per tooth for a 1″ HSS endmill (f t ≈ 0.008 in/tooth) and calculate the plunge feed rate using Equation 3: f [in/min] = N [rpm] × f r [in/rev] cr フロー種類
