Abstract: The purpose of this paper is to recognize and understand the different processes of forging, and to investigate the different defects of forging. Initially some important forging words are discussed which are commonly used in this area. A brief summary on the classification of the forging process based on the working component temperature (hot, cold, and warm forging)and the arrangement of the dies (open, impression, and closed-die forging) is given. The parameters of die design, the requirements for die materials and the selection of proper die materials are discussed in brief. The forging equipment’s (hammer and press) were also briefly described. Factors for the selection of forging machines, features and common forging applications are given. Factors for the selection of forging machines, f features and can forging applications are provided. Forging defects that are occurring regularly are discussed along with their causes and remedies. The fish bone diagram is then used through a brainstorming session to explore the possible causes of defects such as unfelling, mismatch and scale pits and to determine the causes, which may have the greatest effect.
