Modeling of Stress in Drills with Curved Cutting Edges

Abstract

In this paper, it is presented an analysis of the strains and deformation state for a new constructive type of cutting tool the helical drill with three curved cutting edges. The analysis was developed in the application Ansys Workbench, after a definition of the drills geometry in the CATIA environment. It was modeled a specifically load, according to the geometry of the variable working angle of the new drill type. They are presented numerical examples, in comparison with a standard drill, for the diameter of 20 mm.
