Abstract
Keywords
Creating a theoretical framework for high-perfor-mance imple-
mentations of capabilities of the cutting method with outstrip-
ping plastic deformation (OPD), first proposed and developed in
Bauman Moscow State Technical University, requires extensive
research, including metallographic research. In the treatment
area cutting with OPD uses two mechanical sources of energy:
methods of surface plastic strain and cutting. To study the strain
state of the material, method of coordinate dividing grids is
widely used. However, the scientific literature does not describe
a single experimental method of obtaining a deformation field
pattern in the cutting area, which results from the total impact
on the material of two consecutive large plastic strains — from
pressure treatment and the process of cutting, as when cutting
with OPD. We show a new method of applying micro-grids,
which allows us to solve the task of recreating a real pattern of
deformation occurring in the zone of chip formation when
cutting with OPD under the actual operating conditions, the
angles of sharpening the cutting tool and the use of intractable
materials
