Dynamic Aspects of Chip Formation

Dynamic Aspects of Chip Formation A multimass chain model of chip formation in the secondary deformation zone is proposed. The influence of the frictional conditions and cutting conditions on the group motion of the chip elements over the cutter’s front surface is shown. The dynamics of the motion of the chip’s free end has a significant influence on its fracture. In particular, the mass ratio of the last elements involved in the group motion (and positioned on the contact line at the cutter’s front surface) and the free end of the chip gives rise to considerable dynamic splitting forces between the elements. The proposed approach offers broad scope for analysis of the conditions of chip formation, including conditions with intensification of the cutting process by electrical pulses. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Engineering Research Springer Journals

Abstract

A multimass chain model of chip formation in the secondary deformation zone is proposed. The influence of the frictional conditions and cutting conditions on the group motion of the chip elements over the cutter’s front surface is shown. The dynamics of the motion of the chip’s free end has a significant influence on its fracture. In particular, the mass ratio of the last elements involved in the group motion (and positioned on the contact line at the cutter’s front surface) and the free end of the chip gives rise to considerable dynamic splitting forces between the elements. The proposed approach offers broad scope for analysis of the conditions of chip formation, including conditions with intensification of the cutting process by electrical pulses.
