Thermal Deformation of Base Sheet and Local Deformation Around Laser Cutting Edge

Abstract:

When many products were cut out from a wide base sheet by laser cutting in some conditions, an error occurred in a height regulator by the sheet's greatly bending. It is necessary to avoid occurring the error at unmanned processing. We paper investigated local deformation around cutting edge. The cutting path consists of piercing point, terminal point, straight lines, cranks and curves. We measured local deformation around terminal point, crank and straight line. It was clarified that base sheet bent greatly around terminal points and crank and the sheet curved gradually along the straight line. We investigated relationship between global deformation of the base sheet and the local deformation. It was able to presume the entire deformation of base sheet by overlapping the individual deformations around cutting edge.
