Abstract: The geometrical parameters of the drill point, i.e., relief angles, chisel form, web size, and errors of symmetry have a major influence on drill performance. This paper deals with geometrical ...

Abstract: A solution is presented for the temperature field in the chip under experimental edge conditions in the contact zone and at the upper chip face. The pattern of the temperature gradient in ...

Abstract: During metal cutting while products are being manufactured, the access material is removed in the form of chips. These chips are obtained in various shapes which depend on cutting conditions, ...

Abstract: This paper investigates the relationship between drill life, the sound, and the drift forces produced by the drilling process. Tests were performed while drilling steel with 38 in. twist drills. ...
