<p>Sheet materials in the form of optionally flawed remnants with non-repetitive shapes, e.g. hides (10), are cut by digitising the geometry of each remnant, arranging the pieces to be cut out of the remnant, and cutting pieces out of the remnant according to the resulting arrangement. The surface of the remnant (10) is provided with indicia indicating at least the position and orientation of the remnant during the digitising process. The indicia are sensed to determine and record position data representing the positions of the first indicia. In a cutting station (300), images of the indicia positioned according to the first recorded position data are projected onto a work surface, and the corresponding remnant is placed thereon so that the indicia on the remnant surface match the projected images thereof, whereafter said pieces can be cut out of the remnant which now has a position and orientation similar to those it had during the digitising process.</p> |
