Influence of the cutting tool characteristic on the machining process during high speed milling of aluminum alloys By Berend Denkena, Martin Reichstein and Jan H. Dege
High speed cutting, machining forces, microgeometry
This paper describes the influence of the cutting tool microgeometry on machining forces, process stability and surface quality during high speed milling of a wrought aluminum alloy. The results of milling tests with tools of different lengths and angles of cutting edge chamfer are presented and discussed. Only one tool microgeometry showed satisfying results as the milling tests with constant tool and process parameters proved. All other variations of the tool microgeometry caused chatter vibrations with low surface quality. Both, increasing chamfer length and decreasing chamfer angles led to higher feed and feed normal forces.
