On the separation criteria in the simulation of orthogonal metal cutting using the finite element method

  title={On the separation criteria in the simulation of orthogonal metal cutting using the finite element method},
  author={L. C. Zhang},
This paper aims to gain an understanding of the reliability of the existing separation criteria for orthogonal metal cutting. To focus on their physical inherence, a simple finite element model under plane-strain deformation was used to investigate the mechanics of cutting from the incipient stage. The workpiece materials studied were elastic–perfectly plastic and elastic–plastic with work hardening. The chip separation criterion of failure stress was used as a default and based on this the… CONTINUE READING
