Study of thermal deformation of a base sheet caused by laser cutting

In case that a lot of products were cut out from a wide base sheet by laser cutting, the sheet had been much deformed so that the error occurred in a height regulator. This paper deals with thermal deformation of a base sheet caused by laser cutting. We clarified that the thermal deformation was influenced by the cutting sequence in the case of SUS304 sheets of 1mm thickness. The workpieces bent upward in inward sequence, and the workpieces bent downward in outward sequence. It is expected that the deformation was able to be controlled by cutting sequence.
