Machining of Inconel 718 (difficult to cut materials) using cryogenic and non-cryogenic cutting tools
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...

| Summary: | 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. |
