Investigation on burrs in micro milling of stainless steel 310S

In the process of micro milling stainless steel 310S, the influence of milling parameters (cutting depth, a _p , feed per tooth f _z , cutting speed v),and down and up milling method were revealed, which provides reference for controlling burrs of stainless steel 310S, improving surface quality and optimizing cutting process. Based on the orthogonal test method, the coated carbide micro diameter cutter was used and milling experiments were carried out on stainless steel 310S.Top burr size data information was collected and analyzed. Up milling is better than down milling because the shape and size of burr are relatively small. With the increase of cutting depth, the shape of burrs appears long fibrous and tearing and wavy serrated, which means the burr getting large and worse. In order to minimize burrs, it is the good way to choose the sharp cutting tools and up milling, control the cutting depth and select feed rate. (paper)
