| Abstract: | ANSYS,finite element analysis software is used to establish a 3d entity model suited to the analysis of laser cutting sheet metal part.This paper introduces a method to detennine the size of workpiece deformation when it is cutted by laser under its own gravity and the action of the laser cutting heat source, and then simplifies the laser cutting heat source as the gauss heat source,analyzes and calculates the size of worlcpiece deformation when it is cutting by laser by writing APDL program. |

| Keywords: | laser cutting FEM sheet metal part gauss heat source workpiece deformation |
