Abstract

PURPOSE:To prevent an injury accident due to the erroneous irradiation of laser beams by providing projectors to project the laser beams in and oblique direction to detect continuously the relative position between a work and a machining nozzle in the laser beam machining. CONSTITUTION:Luminescent spots on the work 6 by the oblique projections of the projectors for measuring 105, 106, 107 and 108 are projected on a picture display device 4 and the display positional relation with cursors 401, 402, 403 and 404 which are made to a reference is observed. As a result, the relative position between the machining nozzle 501 and the work 6 can be detected easily and continuously. Accordingly, the injury accident due to the erroneous irradiation, etc., of the laser beams by falling-off of the work 6 can be prevented.
