Research on Cutting Depth Effect in Cutting Process

摘要

In the cutting procedure, the cutting depth influences cutting forces, chip breaking, chip shaping, and the distribution status of residual stress. The two-dimension heat-mechanic coupling orthogonal cutting model is established with the FEM analysis software by use of the Lagrange quality point coordinate system description method in this paper. This paper simulates a typical work-piece chip breaking process with different cutting depth, which gets the cutting forces curves and the total status of residual stress distribution and the status.
