Original research EMPLOYING TOPSIS TECHNIQUE TO SELECT OPTIMAL PERFORMANCE OF TURNING PROCESSESPages 165-170
Abstract
Optimization performance of cutting turning parameters considers significant approach to manage metal parts economically throughout machining processes which have a main role in obtaining value added. This research aims to identify the best optimization performance of machining turning parameters, where they achieve lower surface roughness and ultimate rate of removal metal. Three parameters were used in turning operations which are First parameter, the speed of cut, Second parameter, the rate of feeding and Third Parameter, the deepness of cut out. Each parameter has three levels. Technicality for Order Priority by Symmetry to Ideality Solution (TOPSIS) adopted of optimizing multi-objectives simultaneously. Results showed that the best factors of operating were (1500 m/min, 0.5mm/rev, 0.5 mm) because they produced two an optimal attributes were First Attribute, the roughness of surface (1.74 µm) and Second Attribute, the rate of removal metal (375.00 cm3/min).
Keywords: Turning, Optimization, TOPSIS, Roughness.
