Abstract:
A machine for punching a panel on which the position of each hole to be made is identified by a mark, at least some of the holes being capable of having an outline that is not circular, the machine comprising:a structure for receiving said panel, said structure presenting X and Y directions; transfer means for bringing a panel onto said structure in the X direction; means for holding said panel relative to said structure; at least four punch blocks disposed on the structure, each punch block comprising least one punch carrier tool, at least one die carrier assembly, and a support, wherein supports for a first two of said blocks are in the form of a gantry to enable said panels to travel in the X direction between said punch carrier tool and said die carrier assembly of said first two punch blocks, and supports for a second two of the punch blocks are not in the form of a gantry; displacement means for separately moving each punch block relative to said structure in the X and Y directions and in rotation; optical comparator means for comparing the position of each punch block with the corresponding mark and for generating X and Y and rotation position error information relating to each punch block; and control means for separately controlling the displacement means in response to the position error information.
