In this study, we present experimental studies to research the effect of cutting parameters (cutting speed, feed rate and depth of cut) on tool life during the machining of AISI 304 stainless steel by using multi-coated carbide tool on CNC turning machine tools.
High corrosion resistance, ductility and tension strength are the essential properties of stainless steels. Stainless steel is an alloy which has chrome, nickel and molybdenum elements and their machinability is negatively affected. For this reason, the machining of stainless steels is very difficult. In this study, the machining tests were carried out by using coated cutting tools. The tests were performed without coolant at various feed rates, cutting speeds and depth of cuts. Tool life, surface roughness and cutting forces have been determined experimentally. The effect of cutting parameters on the tool life has been researched.
The relationship between cutting parameters and tool life was modeling with surface response methods and analyzed by using SPSS. The results show that cutting speed, feed rate and depth of cut are affected by tool life. Cutting speed is the dominant parameters on the tool life.
