Forging is a core manufacturing process. It gives a product of superior mechanical properties and produces minimum wastage of material. This makes it a better manufacturing process as compared to other processes like casting etc. An aligned grain flow defines a good forging. The effectiveness of a manufacturing process is characterized by low cost, high productivity and high quality of product. This necessitates the use of three dimensional computer graphics and powerful Computer Aided Engineering (CAE) software to analyze the forging process. The present paper discusses on the various research works carried out in different fields of forging. The scopes of further researches on different problems of forging are also elaborated.
