INFORMATION PROJECTION METHOD AND DEVICE AND LASER PROCESSING DEVICE

An information projecting method projects information concerning a cut piece onto the cut piece, which is cut and separated from a plate-like work and is on a placement table, or onto a position adjacent to the cut piece. To adjust to an aspect ratio (vertical to horizontal ratio) of a projector 21,...

Beschreibung
Zusammenfassung:	An information projecting method projects information concerning a cut piece onto the cut piece, which is cut and separated from a plate-like work and is on a placement table, or onto a position adjacent to the cut piece. To adjust to an aspect ratio (vertical to horizontal ratio) of a projector 21, the method assigns a long side of the work W to an X-axis direction, i.e., a horizontal direction of the aspect ratio and a short side of the work W to a Y-axis direction, i.e., a vertical direction of the aspect ratio, finds a positional relationship d between a top face of the work W and the projector 21 according to plate thickness information of the work W on the placement table 7 and 9 positioned corresponding to the projector 21 arranged at a predetermined Y-axis-direction position, and with a zoom ratio based on the found positional relationship d, projects the information concerning the cut piece onto the cut piece or onto a position adjacent to the cut piece.
