Chip formation mechanism at metal grinding

Abstract

The authors proposed and described the method of chip formation a metal grinding based on the representation of the conductivity of perturbations with a fixed velocity in a medium as a part of space. The separation of the cutting micro-chips results from the displacement of the shock wave in front of the abrasive grain resulting in a loss of the shear stability of the material in the local zones of the stress concentrators, the development of the rotational nature of deformation with the structure fragments turning around the axis perpendicular to the direction of displacement of the ‘wheel–billet’ contact zone.
