Forging process control: Influence of key parameters variation on product specifications deviations
TypeCommunications avec actes
Process control in forging industry is essential to ensure a better quality of the product with a lower cost at the end of the manufacturing process. To control the process, a number of key parameters must be monitored to prevent product or forging plan deviations. This paper will illustrate how a variation in a process parameter can create product specifications deviations and how key parameters influence product final state. The illustration work is done on a part obtained via hot forging. An analysis is made on product parameters such as geometry, by varying the key process parameter values previously determined from a created methodology. This later is represented as a decision support system that connects product specifications (geometry, absence of defects…) or other forging specifications (tool wear, involved energy...) to the process parameters.

Impact of experimental conditions on material response during forming of steel in semi-solid state BECKER, Eric; FAVIER, Véronique; BIGOT, Régis; CEZARD, Pierre; LANGLOIS, Laurent (Elsevier, 2010)Semi-solid forming is an effective near-net-shape forming process to produce components with complex geometry and in fewer forming steps. It benefits from the complex thixotropic behaviour of semi-solids. However, the ...
