Abstract

The purpose of this study was to analysis the flank wear and surface roughness resulted between cryogenic treated and non treated carbide by turning process on material ASSAB 718HH. Dry turning machining process was carried out using cutting speeds of 50, 70 and 90 m/min with feed rate 0.10 and 0.15 mm/rev, with the depth of cut 0.50 and 0.75mm. The performances of turning process was evaluated based on the flank wear occurred to the cutting tool and the surface roughness on the work piece. The flank wear was measured by Scanning Electron Microscope while the surface roughness was determined by Surface Roughness Tester. The experimental work showed the cryogenic treated inserts could last longer as the inference with non-treated inserts. The cryogenic treated inserts showed lower value of flank wear with the same amount of process. The reading of surface roughness is lower at the higher cutting speed. The limitation in carrying out this work due to machine vibration had been taken account. This experimental work will ease and provide other researchers with information to proceed with other parameters while turning ASSAB 718HH.
