In this study presents the conclusions of tool wear tests on a new austenitic stainless steel X2Cr16Ni9TiN, which applicated in food processing industry, and describes important concurrent parameters for the cutting zone during the process of finish drilling. The effect of cutting speed are analysed by tool wear mechanisms, and temperature tool. Based on the cutting tests, cutting speeds of 50 to 100 m/min, feed rate of 0.02 to 0.08 mm per rev. and solid a new design of screw drill from sintered carbide with hydraulic holder. Diameter of screw drill is 7.0 mm. Quality outer surface after cutting with roughness parameters down to around 0.54 µm. Very good results were mainly achieved when cutting speed was up 60 m/min to 70 m/min and the feed was interval up 0.02 mm per rev to 0.04 mm per rev. The paper described the cutting process analysis with CAD systems by drilling. Simulation of machining (cutting and drilling). Finite Element Method (FEM) based techniques are used to simulate high speed machining processes and offer several advantages including prediction of tool forces, distribution of stresses, and temperatures, estimation of tool wear, optimization of cutting tool geometry, and cutting conditions.
