MODEL STUDY OF COLD WORKING PROCESS WITH: NEW HORIZON IN FORMING TECHNOLOGY

Abstract

Cold working process is mainly used metal forming process with lots of advantages which to be used to achieve better   surface finish, closer   dimensional   tolerances and improved mechanical properties as compared to hot working processes. Because of widely increasing competition with the advent of globalization it has become very important to keep and improve efficiency of this type of process in manufacturing industries with in terms of optimization with minimum resources and improve product quality. In view of this different models have been proposed and validated using experimental results over a long period of time. The demands in the  automobile industries, energy sectors and mining sectors have led to several modifications in this cold working process. In this paper, details of cold –working process, major analytical, experimental and numerical studies reported in literature have been seen.The review focuses on highlighting the developments associated with the drawing technology that includes improvement  in tool  design, modification in product geometry, process optimization etc. with the use of FEM method to achieve the process related objectives.
