Abstract
A plasma cutting device performs cutting in a plurality of stages. In a first cutting sub-process, a manufactured product is cut out from a base material upon a stage according to an NC program. Next, images of respective regions in the vicinities of proper positions at two corner points of the manufactured product which has been cut out are photographed by an image sensor, the actual positions of these two corner points of the manufactured product are detected from these images which have been photographed, and the translation distances and the rotational angle between the actual positions which have been detected and the proper positions are calculated. The NC program is corrected. And, in a subsequent cutting sub-process, additional cutting for beveling is carried out upon cutting surfaces at the outer circumference of the manufactured product, according to the corrected NC program.
