Title:
SHEET METAL MACHINING SYSTEM, LASER MACHINING MACHINE, SHEET METAL MACHINING METHOD, AND MACHINING REGION SETTING PROGRAM FOR LASER MACHINING
Document Type and Number:
WIPO Patent Application WO/2021/084654
Kind Code:
A1
Abstract:
This sheet metal machining system comprises a laser machining machine for machining a sheet metal inside a laser machining region, a camera for imaging the laser machining region, lighting for illuminating the sheet metal, and a processor for processing images imaged by the camera. The laser machining machine comprises a sheet-like sheet metal supporting member having a plurality of protrusions provided side by side in a first direction inside the laser machining region. The sheet metal is placed on the plurality of protrusions. The camera is disposed so that the optical axis of the camera faces in a direction substantially parallel to the first direction as seen from the height direction of the laser machining machine. The processor detects a bright region in the images as a sheet metal machining region.
