Machinability Study of Duplex Stainless Steel 2205 During Dry Turning
Gaurav D. Sonawane,Vikas G. Sargade 한국정밀공학회 2020 International Journal of Precision Engineering and Vol.21 No.5
Duplex stainless steels (DSS) are preferred replacement to austenitic stainless steel because of their higher strength leadingto economic benefi ts. However, poor ductility and thermal conductivity along with high toughness make them diffi cult tomachine. In the present investigation, tool wear, cutting force and surface roughness were evaluated during dry turning of DSS2205 using tungsten carbide inserts coated with AlTiCrN and AlTiN. High Power Impulse Magnetron Sputtering techniquewas used for coating the substrates. Cutting speeds of 100, 140 and 180 m/min; feed of 0.12, 0.15, and 0.18 mm/rev, and afi xed depth of cut of 0.8 mm were chosen as cutting parameters for dry turning. AlTiCrN coating exhibited highest adhesionstrength of 110 N compared to 89 N by AlTiN coating. AlTiCrN coated tools exhibited highest tool life of 7840 mm, withleast surface roughness of 0.72 μm and cutting force of 255 N. This is attributed to its excellent physical properties such asgood adhesion, higher oxidation resistance and thermal stability, compared to AlTiN coated tool. AlTiCrN and AlTiN coatedtools exhibited respectively 6-times and 4-times more tool life than uncoated tools. Combination of high speed (180 m/min)and low feed (0.12 mm/rev) resulted in least surface fi nish. Regression model developed from the experimental data showedcloser agreement (95%) between predicted and experimental values of surface roughness.
