Abstracts: In manufacturing industries physical defects which occur during metal forming processes. These defects, which may occur on the surface or be internal, are undesirable not only because of the surface appearance, but because they may adversely affect the strength, formability and other manufacturing characteristics of the material .Defects in forging reduce its strength. They occur for a number of reasons including Faults in original metal, incorrect die design, improper heating and lubrication. Some physical defects in metal forming processes such as rolling and forging, Defects in forging reduce its strength. . They occur for a number of reasons including faults in original metal, incorrect die design, improper heating and lubrication. Defects of forged product include exterior cracking, interior cracking, laps, cold shuts, warping of the part, improperly formed sections and dead zones. In this project we will analysis the metal of forging and try to reduce metal defects in forging processes. Finite element analysis is used to predict residual stresses in forging processes.
