Comparison Analysis of Plastic Deformation in Metal Cutting with Cutting Simulation and Streamline Model

Abstract:

Strain and strain rate are two important parameters evaluating plastic deformation of workpiece in cutting process. Finite element simulation is implemented to estimate plastic deformation of wokrpiece in this paper. Flow net function in simulation is used to capture deformation state of grids on workpiece, and the deformation result is compared with that observed by Stevenson and Oxley in cutting test. Point tracking function in simulation is utilized to calculate strain and strain rate distribution along flow lines, and the results are also compared with that calculated by streamline model.
