A Johnson–Cook material model with an energy-based ductile failure criterion is developed
in titanium alloy (Ti–6Al–4V) high-speed machining finite element analysis (FEA) …

The present work will provide an in-depth analysis of the abrasive-grain cutting process
using a combination of experimental observations and finite element simulations. The …

Research on the underlying mechanism that controls the chip deformation and energy
consumption is a basis to instruct the cutting process planning and improve the machining …

Evidence of ductile fracture leading to material separation has been reported recently in
ductile metal cutting [S. Subbiah, SN Melkote, ASME J. Manuf. Sci. Eng. 28 (3)(2006)]. This …

The analysis of SCE (specific cutting energy) is vital for determining the machining
efficiency. Conventionally, the machining forces are used to determine SCE, which is …

Chip segmentation results in fluctuation of the cutting force, deteriorated tool wear and
surface finish, thereby plays an important role in the machining process. Although extensive …

Metal matrix composites, due to their excellent properties of high specific strength, fracture
resistance, and corrosion resistance, are highly sought after over their nonferrous alloys, but …

The computational and experimental assessment of light-weight proppants are undertaken
to identify their effectiveness and efficiency to replace sand enlisted in hydraulic fracturing …

In the conventional use of vibration-assisted machining the vibratory motion is applied to the
tool either linearly along the direction of the cutting velocity or elliptically in the plane …

This paper appraises two major chip formation techniques in finite element (FE) simulation
of machining. The first one considers chip formation as a wedge indentation process, while …
