Study on Residual Stress in High-Speed Cutting NAK80 Mold-Steel

Abstract:

An orthogonal cutting model was presented，and the cutting process was simulated by a finite element software based on the thermal-elastic-plastic FEM theory and updated Lagrange method.We obtained the distributions of residual stresses in machined layer of NAK80 mold-steel.The effects of cutting speeds，cutting depths and tool geometry on residual stress distributions were investigated. Comparing to experimental results，the conclusions are more accurate.
