The influence of cutting speed, feed and coatings on tool-chip friction when machining AISI 1045 is analysed. The results demonstrate that the new methodology can replace the more difficult to use and less robust split-tool method. They confirm two clearly different contact zones: i) the sticking region, governed by the shear flow stress of the workpiece and ii) the sliding region, where the friction coefficient is higher than 1. 0007-8506 https://katalogoa.mondragon.edu/janium-bin/janium_login_opac.pl?find&ficha_no=163266 https://hdl.handle.net/20.500.11984/5270 Friction Machining Tribology Temperature A novel methodology to characterize tool-chip contact in metal cutting using partially restricted contact length tools
