| Abstract: | Conventional laser machining used high temperature to melt and gasify the material to achieve the machining purpose.But the thermal soften and thermal stress is harmful to machining in conventional laser machining.Two kinds of unconventional laser machining technologies including laser assisted machining(LAM) and 3-dimensional laser forming(3DLF) that used thermal soften and thermal stress effect were indicated.It was expatiated on the temperature field changes,cutting chips deformation and the machined sur... |
