Mathematical modelling of the helical surfaces of the drill in the Mathcad environment

This article provides a complete algorithm that allows you to form a parameterized mathematical model of the drill profile in the end section. On the basis of the constructed profile, as a generatrix of the helical surfaces, it becomes possible to form an accurate mathematical model of a twist drill, depending on the basic geometric parameters.

Keywords: cutting tool, helical surface, mathematical model, an algorithm, flute.
