Description
Summary:Engineered surfaces are commonly designed to achieve certain desirable functionalities. Manufacturing of engineered surfaces often requires innovative techniques. In this paper, a sheet metal surface with pin fin features is proposed for potential thermal or fluid flow management applications. Experiments and numerical simulations were carried out to demonstrate that extrusion-forging process can be used to create such micro scale surface features. Preliminary results from simulations also show that it is feasible to use extrusion-rolling process to manufacture pin fin features to increase productivity and reduce cost. The work suggests that extrusion-rolling technique has good potential for large scale manufacturing of various innovative surfaces features.
