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 new approach to the macro-level optimization of tool geometro in machining is proposed. Methods for characterizing the tool material, the work material and the optimum tool geometry are ...

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, ...
