Feed-Speed mm/min HIGH-FEED MILLING

milling cutter. A cutter with a 90° entry angle has no benefit of chip thinning as the feed per tooth at 0.2 mm only creates chips 0.2 mm thick (Fig. 1). In the case of a cutter with a 45° entry angle, feed per tooth at 0.28 mm creates chips 0.2 mm thick (Fig. 2), which allows the feed to be increased, resulting
