A STUDY OF STRENGTH ANALYSIS IN SHEET METAL BY BENDING PROCESS: A REVIEW

Various types of bending process are designed as per shape and thickness of work piece. The strength of sheet metal varies with the shape due to bending. The change in shape causes the change in moment of inertia. The bending also cause change in material properties. The bending leads to strain hardening of the material. The sequence of bend and lot size also criteria in process planning. The time to change the tool and traveling time with thickness of sheet are also the criteria
