Process to vary with a laser beam and the topography of coated sheet coated with a variation of its topography plates.

摘要

Procedure laser machining of coated sheets, in which is generated by the laser on at least one side of at least one plate one topographical change protruding from the surface, wherein the laser beam generates the at least one variation topography made through and / or around the center of its machining area a movement transverse and longitudinal components, such that the topographical change present a tip radius which is greater than the height of the topographical change, being defined height from the deepest position of the sheet sag at the base of the topographical change to the tip thereof.
