This paper deals with the thermal deformation of a base sheet caused by cutting out a lot of products to avoid the situation that the laser cutting is interrupted by the deformation of the base sheet. In experiments, we cut several kerfs in stainless sheets by various cutting conditions. We considered the deformation to be difference between the waviness profiles which measured before and after the laser cutting. The base sheet bent upward or downward according to the cutting order. The sheet bent upward when the processing was advanced from the edge to the center. And the sheet bent downward in the case of the inverse order. It can be expected that the deformation of the base sheet can be reduced by appropriately setting the cutting order.
