Paper Title:
Numerical Simulation of Orthogonal Cutting Process of a Kind of Difficult-to-Cut Material
  Abstract

A orthogonal cutting of a kind of difficult-to-cut material is simulated using a finite element model, which is considered dynamic effects, thermo-mechanical coupling, tool-chip friction, chip separation criteria. Marc program is the computational tool in the model. Johnson-Cook’s model is employed as the constitutive law for the workpiece material. The frictional behavior of the sticking and sliding tool-chip interface is described by Coulomb’s law. Remeshing technique and mesh adaptive technique are also used. The research mainly specializes plane strain and continuous flow chip. The emphasis is placed on the parametric modeling of tool and workpiece. Then the cutting force and temperature in cutting process from initial state to steady state is conducted by simulation. Finally the Experimental value is compared with the simulated data.
