Chipping and crushing mechanisms in orthogonal rock …
The rock removal mechanism in the rock cutting process includes crushing and chipping failure modes. Crushed and powdery chips are attributed to the crushing mode while chunk-like chips are formed due to the chipping mode. Chipping of rock has been concluded to be caused by either tensile or shear stresses by different researchers.
