Influence of plastic instability of near-contact chip layers on the wear mechanism of a carbide tool

The mechanism of plastic deformation of the incised chip layer during cutting of carbon steels and titanium alloy is investigated. It is shown that high degrees of deformation cause melting and the vortex nature of the movement of particles of the processed material in it, causing intensive wear of the carbide tool.
