Some aspects of machining with negative rake tools simulating grinding

Abstract In this paper, experimental results of machining with a wide range of negative rake tools are presented. It is shown that when machining with tools up to nearly −90 deg. rake, either chips may be produced or the metal may be ploughed. The parameters determining this are—the rake angle and the width of cut. The transition from cutting to ploughing is dependent on the friction conditions on the rake face.
