Experimental study of burr formation and tool chipping in the face milling of stainless steel

This paper reports the results of experiments to investigate burr formation and tool chipping during the face milling of stainless steel, using a fly milling cutter to carry out single-tooth face milling tests. It is found that the burr height is strongly dependent upon the milling process . The results show that five different types of burr can be produced on the exit edge, e.g. knife-type, saw-type, burr breakage curl-type and wave-type. A large depth of cut contributes to the formation of the wave-type burr. With high feed rate, the cutting edge of the tool is chipped, with a built-up edge. At high cutting speeds, small masses of material from the rake face of the tool can come off. With large depth of cut, large cavities can be created in the rake face of the tool.
