ANFIS System for Stress Prediction of Cold Heading Fastener Body Process for a Steel Base Composite Aluminum

The cold heading process has been widely used for metal forming with different types of materials, particularly for producing fastener bodies, which are applied to various industrial applications. Presently, new material composite types are considered to obtain lightweight designs. However, the process parameters are needed by the experiment, but it takes time and high effort. This paper proposes the development of the ANFIS system for the prediction of stress in the cold heading process of the fastener body by modeling. Three parameters are considered: heading ratio, material strength, and step of heading. The result is then tested on the stress flow of the composite material to confirm workable parameters. The stress represents the perfect strength of the fastener. The originality of the article is applied modeling simulation to find a new raw material for cold forging using for the fattener body production which required the strength and light weight for a given application.
