Implications of high strain deformation in grinding

Abstract

In the present study, simple grinding experiments are carried out which suggest that the fragmented zone can give rise to metal removal in the form of thin delaminated wear platelets. These are evident when grinding in an inert atmosphere and take the form of oxide spheres (sparks) when grinding in air. In this study well formed burrs were observed in `interrupted cut' grinding whereas in more continuous grinding, redeposition is suggested to be a contributor to burr formation resulting in a partial breakdown of the burr.
