초록
EN25 Steel possesses higher mechanical strength and corrosion resistance. Due its excellent properties, this work material isused in heavy duty driver shaft. Turning of EN25 steel is complex and determination of optimal turning process parametersis highly required to improve the cost effectiveness. In this research work coated carbide insert are used as the cuttingtool material to turn EN25 steel in the CNC machine. The turning process parameters considered in this work are cuttingspeed, feed rate, depth of cut and type of the tool. The responses considered in this work are Tool life, surface roughnessand material removal rate. Multi criteria decision making is a new decision making method which is used to rank the bestalternatives among the given optimal solutions. In this work the technique for order performance by similarity to idealsolution (TOPSIS) technique is used for solving the multi criteria decision problem. ANOVA analysis is also used to checkthe adequacy of the model.
