Laser cutting process for film coated metal plate

The invention relates to the technical field of a laser cutting process, in particular to a laser cutting process for a film coated metal plate. The laser cutting process for the film coated metal plate comprises the following steps of: (1) placing the film coated metal plate which needs to be cut on a laser machine station; (2) burning out a film, i.e. under the action of compressed air, burning out the surface coated film of a path track of the metal plate, which needs to be cut, so as to form a film burning track with the width of 1 to 2.5mm; and (3) carrying out laser cutting along the film burning track to form a required workpiece. After the film burning track on the cutting path is formed by burning the film, the normal cutting process is carried out, so that the problems of shifting of the metal film coated plate, malposition of the cutting path, scrappage and the like in the process of cutting a conventional metal film coated plate are avoided; the problem that reverse slags are formed on the surface
