The Influence of Milling Tool Geometry on the Quality of the Machined Surface

Abstract

One of the most important things for a milling is know which material would to be machined. Different milling conditions are required for each type of material and it is not possible to use just one type of milling tool if we want to have the best efficiency. Therefore different setting of tool geometry is used for different materials.In end mills change of rake angle has an effect on plastic deformation, chip making and forces from machining. For changing surface quality, friction and toughness of mill, we must change the clearance angle on the tool. The next angle, which we can find, on the tool is the edge angle and it is given by the previous two angles. The helix angle, which sets which direction the chip goes out, depends on vibration or the number of edges, which will be in the cut.Three end milling variations, which have different degrees of geometry change, were suggested. They are based on current end mill from hard metal. More information and results are available in the article.
