Abstract:
1. Method for bending a portion ( 24 ) of an element ( 11 ) in a bending machine ( 12 ), comprising at least a bending assembly ( 14 ), a supporting plane ( 18 ) on which said element ( 11 ) is retained by an arm ( 16 ), and an electronic processing unit ( 32 ), wherein the bending process is filmed by image acquisition means ( 26 ) and displayed on display means ( 36 ), the method comprising a step of setting a nominal value (“γ”) of the angle of bend to be obtained, characterized in that it provides that: the arm ( a movement of the bending assembly ( a first reference indicator (“Z”) is positioned on said display means ( the value of an angle of deviation (“α”) is determined, caused by an elastic return of said bent portion ( the portion ( the new movement of said bending assembly (
