| Popis: | The study of machining nickel-based superalloys has assisted in developing new techniques associated with cutting processes and tools. Hastelloy® X offers ideal properties for engine manufacturing in the aerospace and aeronautical applications that require high surface qualities. Thus, this work investigates the effects of three input parameters (cutting speed, depth of cut, and lubricooling conditions) at three levels on the average roughness values in the finish turning using a PVD-coated carbide tool. The 0.1 mm/rev feed rate was kept fixed, and the parameters were combined, randomized, and optimized by the Box-Behnken Design of Experiment. The statistical results showed that the most significant input parameters were cutting speed and depth of cut and their respective interactions. Furthermore, the cutting conditions with lower cutting speed and depth of cut above 1.5x tool nose radius generated high roughness values due to chatter vibration. After optimization, the best average roughness value obtained was below 0.8 µm, with a 400% increase in the material removal rate. |
