Machining of Hard-to-cut AISI 4462 Duplex Stainless Steel with an Environmentally Friendly Approach with Vortex Tube

Machining is a manufacturing process that can be used to produce precision machine parts and has many advantages. The first the ability achieve superior surface quality. Tool wear an inevitable phenomenon occurs during machining. It affected by machining conditions; therefore, this needs monitored controlled. In study, tool roughness tests were carried out on AISI 4462 duplex stainless-steel materials, known hard-to-cut material. For purpose, analyses implemented using environmentally friendly vortex tube cooling system in addition wet turning conditions for time. both methods, experiments conducted at 1 mm depth of cut, 120 m/min cutting speed, 0.1 mm/rev feed with 90 length each pass. Both examined end analysis showed gave better results terms life (19.8 minutes life) compared 11.1 turning. contrast, values differed up two times some experiments, all passes. addition, less built-up-edge (BUE) formation than wet-turning experiments.
