Abstract: In this paper, the effect of machining parameters including cutting velocity, feed rate, and tool material on machining power of EN-AC 48000 aluminium alloy has been studied. A L27 Taguchi's standard orthogonal array has been applied as experimental design to investigate the effect of the factors and their interaction. Twenty seven machining tests have been accomplished with two random repetitions, resulting in fifty four experiments. EN-AC 48000 is an important alloy in automotive and aerospace industries. Machining of this alloy is of vital importance due to build-up edge and tool wear. Machining power is an essential parameter affecting the tool life, dimensional accuracy, and cutting efficiency. Three types of cutting tools including coated carbide (CD 1810), uncoated carbide (H10), and polycrystalline diamond (CD10) have been used in this study. Statistical analysis has been employed to study the effect of factors and their interactions using ANOVA analysis. Moreover, optimal factor levels have been presented using signal to noise ratio (S/N) analysis. Also, regression model have been provided to predict the machining power. Finally, the results of confirmation tests have been presented to verify and compare the adequacy of the predictive models.

Abstract: Automation of industrial activities is one of the most essential needs in recent years since the operator has smaller role in the process. Creation of the various robotic systems in the different industries causes relaxing the operators from working in hard positions, increases the accuracy, efficiency and velocity in the process and decreases the wastage and price of product. In this paper, the study on melting station and continuous casting line in Mobarakeh Steel Complex is provided. The needs for elimination of difficulties and increasing the automation level of steel slabs casting line with checking the all stations from robotic and automation point of view for stations with the capability of automation system necessitates a suitable robotic system. In this case, selected robot should be able to support the velocity, accuracy, load capacity and other characteristics. Considering the sensitive conditions around the electric arc furnace (E.A.F), a suitable sampling robot with 3-degree freedom in which all three joints moves in revolute form (RRR) has been designed.
