As a traditional high energy-consuming industry, the forging industry consumes a lot of energy. The activity consuming highest energy during forging process is the forging and heating. In order to solve the problem regarding how to separate work pieces with different holding temperature intervals and combine them for charging, a group of work pieces with compatible holding temperatures are anal...

This paper describes a review of automation techniques as currently practiced in the forging and forming industry. That industry has been relatively resistant to handling automation because of the severe challenges that are faced by having typically small batch sizes, extremely challenging operating conditions in terms of temperatures and pressures and lighting conditions. The paper discusses h...

Editorial Forging Ahead 'All I know,' wrote Seamus Heaney, 'is a door into the dark 1 .' Me too. The world of radiology is figuratively and perhaps, on occasion, literally just that. Our game is the image, not the written word. Pretty pictures. Yet, now we increasingly find ourselves integral to the medical paradigm. This, clearly, is no reflection on us, but underpins the requirement, primacy,...

The main body of primary system valves discussed in this paper is made of stabilized austenitic stainless steel and are of intricate shapes & sizes. These bodies are produced through close die forging route and are manufactured first time in Indian forging shops. Finished forgings produced through three stage close die forging process are subjected to comprehensive quality assurance plan at eac...

Abstract— Forging is a very complex process and the measurement of actual forces for real material is difficult and cumbersome. The main objective of this document is to use the analytical methods for measuring parameters such as load, and stress distribution of forging process and use them to make simple, reliable, fast and non-expensive simulation tools, contrary to the commercial software’s ...

We consider thermal fluid structure interaction to model industrial gas quenching in steel forging, where hot steel is cooled using cold high pressured gas. This allows to define properties of the finished steel part, as for example yield strength, locally at low cost and without environmental problems. For the numerical simulation, a partitioned approach via a Dirichlet-Neumann coupling and a ...

Cold forging is widely used in many industries. Multi-stage cold forming usually utilized fasteners. In this study, numerical simulation and experimental investigations were carried out on a five-stage cold-forming process for the manufacturing of low-carbon steel AISI 1010 relief valve regulating nuts. The through five stages included preparation centering backward extrusion, extrusion over di...

The finite element method plays an extremely important role in forging process design as it provides a valid means to quantify forging errors and thereby govern die shape modification to improve the dimensional accuracy of the component. However, this dependency on process simulation could raise significant problems and present a major drawback if the finite element simulation results were inac...
