Contribution à la mise en place d’une méthodologie générique de contrôle des processus de forgeage dans le but de maitriser les moyens de production

Abstract : The mastering of the forging process is one of the principal objectives of the forging industry. To master a forging process, the key process parameters must be identified and controlled through a specified methodology. Some controlled parameters exist, like the stroke length or the lubrication, which are identified and controlled through a systematic approach. Their control depends on the part to produce or on customer's constraints, rather than a rational approach. A methodology is proposed to master the forging process and to avoid a process deviation. There are some methodologies that already exist such as the DMAIC, but it has certain drawbacks. The aim is to develop a generic methodology to improve the forging process monitoring. The methodology uses two systems in the upstream and the downstream of the forging process. The first system is a decision support system that connects product specifications (geometry, absence of defects…) or other forging process specifications (tool wear, energy…) to the process parameters, using the empirical rules and physical laws. The first system determinates the key parameters to control in order to avoid product variable deviations. The second system is a learning system, this latter helps in process understanding, supply the decision support system with laws and determinate the control pertinence.
