Title:
LASER MELT-CUTTING METHOD AND PLATE-FORM GLASS PRODUCT HAVING MELT-CUT FACE
Document Type and Number:
WIPO Patent Application WO/2015/115604
Kind Code:
A1
Abstract:
When irradiating a laser (11) onto a workpiece (1) having a plate form, while causing the laser (11) to scan along a planned cutting line which is a closed curve (4) on the workpiece (1), and melting the workpiece (1) in order to cut the work piece (1) into a product portion (2) and a non-product portion (3), the method adopts a trajectory wherein the laser (11) is caused to enter from the non-product portion (3) side onto the planned cutting line (4) and scan along the planned cutting line (4), and then the laser (11) is caused to leave from above the planned cutting line (4) to the non-product portion (3) side. Then, a leaving start position (P4), which is where the laser (11) starts leaving from above the planned cutting line (4), is offset more to the tailing side of the laser (11) scanning direction than an entry start position (P3), which is where the laser (11) starts entering onto the planned cutting line (4).
