“…Cotterell and Byrne [29], performed experimental tests in orthogonal cutting conditions (rake angle equal to 6.51) and cutting velocity ranging from 0.067 to 2 m/s. Cutting forces, temperature distribution, tool-chip contact length and the shear angle, were obtained for different values of the feed (50, 75 and 100 μm).…”

This work is focused on the numerical analysis of adiabatic shear banding in orthogonal cutting of Ti6Al4V alloy. Segmented chip results from adiabatic shear banding, depending on the competition of thermal softening and strain and strain rate hardening. The influence of cutting velocity and feed in the chip segmentation is studied. Also the role of friction at the tool-chip interface and the effect of rheological parameters of the constitutive equation are analyzed. Experimental tests obtained from previous work of the authors [Molinari A, Musquar C, Sutter G, Adiabatic shear banding in high speed machining of Ti-6Al-4V experiments and modeling, Int J Plast, vol. 18, 2002, p. 443-459] and others were used as a reference to validate the models. Cutting forces and the mechanism of plastic flow localization are analyzed in terms of frequency of segmentation and shear band width and compared to experimental data.

“…Their results indicated that the cutting speed or higher feed rate is likely at the disruption of the chip. Cotterell and Byrne (2008), have studied the dynamics of chip formation in orthogonal machining of titanium alloy and demonstrated that disruption frequency of chip increased linearly with increasing cutting velocity. Pusavec (2012), has compared the machining of the tungsten of cryogenic method with the method of plastic injection and has considered its impact on some cutting parameters, cutting tool and the surface porosity.…”
