WebIt was proved that the cause of chip curling is due to the bending moment formed at the deformation zone, owing to the non-colinearity of the resultant force on the rake face and the resisting force on the shear plane. The criterion for chip breaking consists of the sum of two bending strains: (1) The bending strain caused by the cutting ... WebJul 11, 2002 · The essential differences are illustrated between the chip lateral-curl concept and the “chip-twisting” concept presented in other related studies. Based on an analytical vector analysis, a new kinematic characterization is presented for the natural (or born) lateral-curl of the chip that is associated with flat-faced tool machining.
