TL;DR: Initial results from AFD show that it can be a powerful tool for designing geometries for the rib-web type of forgings and a combination of knowledge-based and algorithmic techniques was employed to implement the AFD system.
Abstract: This paper describes a method and a system to automate the design of forging geometries. The method is derived from the principles and the actual practices of forging design used by experienced forging designers. Due to the diversity of the knowledge and problem solving techniques required for forging design, a combination of knowledge-based and algorithmic techniques was employed to implement the AFD (automated forging design) system. Given a set of design specifications, that is, machined part geometry, processing conditions, and special design considerations, the AFD system designs the forging section geometry automatically. Initial results from AFD show that it can be a powerful tool for designing geometries for the rib-web type of forgings.

TL;DR: In order to remaincompetitive with other manufacturing processes, metal forming processes are being improved by using computer-aided techniques and by developing novel tooling designs to increase part complexity and precision as mentioned in this paper.
Abstract: In order to remaincompetitive with other manufacturing processes, metal forming processes are being improved by using computer-aided techniques and by developing novel tooling designs to increase part complexity and precision. In addition to the application of CAD/CAM, which is fairly common in industry, expert systems and metal flow simulation techniques are being developed and introduced to practice. This paper describes some of the advances achieved in metal forming research and gives practical examples of computer simulations in forging.

TL;DR: In this article, the authors discuss the interactions between press characteristics and part production in precision forming and review some of the new press and tooling designs recently developed by various domestic and foreign manufacturers.
Abstract: The trend in metal forming is to produce parts with increased precision and geometric complexity. Thus, research and development is being conducted worldwide to develop presses and tooling for near-net and net shape forming of difficult-to-form components. As a result, presses with increased precision and multi-action tooling are being used routinely by advanced companies around the world. This paper will discuss the interactions between press characteristics and part production in precision forming and review some of the new press and tooling designs recently developed by various domestic and foreign manufacturers.
