Abstract
Keywords
The article supplies the results of modelling the micro-
cutting process for a single pyramid-shaped abrasive
grain in preset modes featuring various cutting thick-
nesses and grain axis inclination angles (the rake angle of
the cutting wedge). We investigate the processes of
elastoplastic deformation, chip formation, cratering,
built-up edge formation and burr formation when the
tool cuts into materials; we also determine the ratio of
cutting area to cutting force. To compute the stress-strain
state parameters, we used the Johnson–Cook material
model that takes into account temperature along with
strain rate and level. We solve the stress-strain state
problem as stated together with the problem of
temperature in the workpiece material. We determine
cutting force coefficients and study the effect of rake
angles in the grains on the cutting force coefficients
