Abstract
This paper reviews the application of systems approach to massive forming processes. A detailed classification of massive forming processes is given and using impression die forging as an example, the significant process variables and their interactions are systematically discussed. The paper also gives an example in forging, which illustrates the application of the systems approach to modeling of forging, a massive forming process. Finally, the future potential, capabilities and shortcomings of process modeling are discussed and recommendations for future work are made. It is expected that the paper can be useful to the metalforming engineer, active in research or production, who is interested in systematic analysis and design of massive forming processes.
