Investigating the performance of 410, PH13-8Mo and 300M steelsin a turning process with a focus on surfacefinish Alegre García, Raul ARRAZOLA, PEDRO JOSE Taylor, Chris M. Díaz, Fernanda Khan, Thawhid Griffin, James Turner, Sam Hardened steels Turning Surface finish Machinability This study generated novel behavioural data for three engineering steels undergoing a turning process. The materialswere hardened 410, PH13-8Mo and 300M, two stainless steels and one high strength steel respectively. A primary aimwas obtaining lowmachined surface roughness. A surface finish investigation compared tool geometries and tool materials.Multi-response cutting parameter screening was undertaken using a novel trade study and iteration method, where the calculated cut quality was used to identify better feed rates and surface speeds. In addition the sub-surface machined microstructure was examined. Tools with a small nose radius produced the roughest surfaces. A surface roughness below 0.4 μm Ra could be consistently achieved on all three materials using rhombic wiper inserts and a feed rate up to 0.1 mm/rev. PH13-8Mo had the lowest machined surface roughness, as low as 0.11 μm in terms of Ra. In the parameter screening stage a generalised recommendation for good cut quality was a surface speed of at least 120 m/min and a feed rate of 0.088mm/rev. The microstructure examination showed that for all materials under the conditions tested, therewas no evidence ofwhite amorphous layer formation and therewas grain deformation for the 410 material only. 2020-09-02T10:06:09Z 2020-09-02T10:06:09Z 2020 http://purl.org/coar/resource_type/c_6501 0264-1275 https://katalogoa.mondragon.edu/janium-bin/janium_login_opac.pl?find&ficha_no=159514 https://hdl.handle.net/20.500.11984/1809 eng Attribution-NonCommercial-NoDerivatives 4.0 International http://creativecommons.org/licenses/by-nc-nd/4.0/ © 2020 The Authors Elsevier Ltd.
