Abstract

In this paper, it’s analyzed a new method of building crooked cutting edges for helical drills, through decreasing of the size of rake angle from working plane. It’s proposed an analytical modelling and, therewith, a 3D modelling of rack angle sizes along cutting edge, through accomplishment of a new building form of helical drill main cutting edge.
