摘要：This paper deals with experimental analysis and numerical simulation of the stainless AISI 304 steel fric-tion drilling process. During fiction drilling, thermal and plastic material processes take place: temperatures in the contact zone vary in a very wide range reaching the metal melting temperature, thus, large-sized plastic deformations occur in the material around the forming hole. Also, the parameters of this process are constantly changing during the drilling due to the complicated shape of the tool. Therefore simulation of friction drilling is a very complex problem. For this reason a friction drilling experiment was carried out. Variations of experimental axial force and torque values were obtained and compared to finite element simulation results and a conclusion was made that the presumptions taken in the simulation are correct and realistically define the friction drilling process.
