This study is focused on thrust force analysis of the drilling burr formation. A finite element model (FEM) for drilling burr formation was proposed with a stainless steel (AISI 304L) workpiece and a conventional twist drill. The thrust force variation during drilling process from FEM was obtained and compared with the experimental results. The estimation of burr size was briefly discussed.
