The analytical method for prediction the mechanical state of the machined surface with FEM was proposed. The flow type chip formation process at low velocity was simulated. As flow type chip formation process is one of the large deformation problems, geometrical nonlinearity and relaxation of over constraint of incompressibility were introduced into the finite formation. A special geometrical separation method of work material at the front of tool edge was also proposed instead of fracture stress criterion and the availability of the method was discussed. Through the simulation, the residual stress and strain distributions within the machined sublayer were analytically calculated. The distortion of work after released from chucking system, caused by rearrangement of residual stress distribution, was also obtained. These analytical results were compared and discussed with the experimental one.
