Abstract

The multi flute drills with curved cutting edges are new constructions, particularly from their performance point of view regarding the common helical drill with two cutting edges. This paper presents a simplified geometrical model of the roughness of surfaces machined using drills with two straight lined cutting edges, versus a similar model for machining using drill with three curved cutting edges. At the same time, the experiments emphasis parameter values which define the roughness (Ra and Rq) at machining of A570 steel (OL 37) and the profiles resulted for various cutting conditions. The paper shows the influence of the working conditions regarding the machined surface.
