Abstract :

Optimization performance of cutting turning parameters considers very important 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 upper removal material rate. Three parameters were used in turning operations which are cutting speed, depth of cut, and feed rate that have three levels of each parameter. Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) was adopted to optimize multi objectives simultaneously. Results showed that the best operating factors are (Cutting Speed=1500 m/min, Feed rate= 0.5mm/rev, Depth of Cut =0.5 mm) because they produce surface roughness (1.74 µm) and removal material rate (375.00 cm³/min) in the same time. Conclusions illustrated that TOPSIS technique was effectively employed to identify relative closeness throughout negative and positive ideal solutions of each experiment.
