00925njm 22002777a 4500 dc ARRAZOLA, PEDRO JOSE author 2016 Noteworthy results have been obtained in the turning and drilling of hardened high-strength steels using tungsten carbide based cutting tools. In a finish turning process, it was seen that surface roughness and tool flank wear followed very different trends against cutting time. The suggested explanation for this behaviour is that the profile cut into the workpiece surface is determined by the tool’s cutting edge profile. It is shown that the profile appearing on the cut surface changes rapidly over time, so the profile of the tool cutting edge should also be changing rapidly. Workpiece material adhered onto the cutting tool, which is also known as a built-up edge, is a phenomenon which could explain the observations made. In terms of tool damage modes, workpiece material adhesion is believed to have contributed to tool wear in examples provided from finish turning, thread turning and drilling. Additionally, evidence of tool fracture and tool abrasion were recorded. 1307-6892 https://katalogoa.mondragon.edu/janium-bin/janium_login_opac.pl?find&ficha_no=124725 https://hdl.handle.net/20.500.11984/5753 Turning Drilling Adhesion Wear Hard steels Tool Damage and Adhesion Effects in Turning and Drilling of Hardened Steels
