Procedure for the dynamic correction of the bending angle of sheet metal on a panel bender machine
Described is a procedure for bending a sheet of sheet metal on a panel bender machine wherein upon bending the sheet of metal sheet a first software (BE) for machine control transmits to a second software (VS) for management of a TV camera (17), positioned in alignment with the bending line, the data relating to the nominal bending angle, the bending length, the distance of the bent edge from the center line of the panel bender and the thickness of the metal sheet. The second software (VS) acquires an image of the bent metal sheet, identifies the spatial position of the straight line corresponding to the bent edge of the sheet of sheet metal and then calculates its geometric coordinates in accordance with a preset referencing system, and supplies to the first software (BE) the value of the angle of the bend performed. The machine control is returned to the first software (BE), which calculates the difference between the angle of the bend actually performed and the angle of the nominal bend and then orders the start of a new bend corresponding to the angular difference, thereby obtaining a bend corresponding to the nominal bend.
