CONTROL DEVICE AND LASER PROCESSING DEVICE COMPRISING SAME, AND METHOD FOR CONTROLLING DISPLACEMENT OF PROCESSING START POINT OF LASER EMISSION MECHANISM OF LASER PROCESSING DEVICE

WIPO Patent Application WO/2023/209792

A1

The present invention relates to: a control device for a laser processing device comprising a laser emission mechanism that emits processing laser light in a direction along a unit vector, and a gap sensor provided in the laser emission mechanism; and a method for controlling displacement of a processing start point. The control device comprises: a main control unit that outputs a driving command to a constituent element of the laser processing device on the basis of a processing program; and a displacement command generation unit that generates a displacement command for displacing the laser emission mechanism using a detected value from a gap sensor. The displacement command generation unit has a function of generating: an approach command for displacing the laser emission mechanism from a control start position toward a laser irradiation point to a boundary gap point where the gap sensor starts detection; and a processing start point displacement command for displacing the laser emission mechanism from the boundary gap point to a processing start point within a detection range of the gap sensor. The processing start point displacement command includes a pose change that matches the unit vector at the boundary gap point with a processing vector at the processing start point.
