Press release |
In the forging industry, which is dominated by small and medium-sized enterprises (SMEs), the lifetime of forging dies is usually determined on the basis of empirical values and subjective decisions. Particularly in SMEs, a decision often has to be made as to whether and under what risk factors a forging die will continue to be used at the limit of its lifetime. In order to avoid considerable logistical and economic expenses as a result of unplanned downtimes and tool failure, the lifetime is often set many times lower and a waste of the remaining tool lifetime is caused.
Within the project VorÜber a solution shall be developed to fully utilize the lifetime of the used forging tools under existing quality specifications. For this purpose, an application-oriented method for the predictive monitoring of the wear-related condition of forging tools will be developed. A detailed process control can enable a reduction of maintenance effort and downtime.
Publications about the project
Wear due to thermal and mechanical stresses is one of the major causes of forging die failure. The assessment of die condition and the associated die life is usually based on experience. This paper presents a method to objectively predict the remaining life of a forging die. With this method a prediction based on optical measurements can be calculated. Practical tests show the possible applications. In addition, force measurements are performed and analyzed to determine how wear affects the force distribution in the die. The assessment based on optical measurements allows objective statements about the remaining tool life of forging dies. The analysis of the force measurements shows potential for predicting tool life but needs further investigation.

Process monitoring strategies allow wear-related conditions of forging dies to be detected and predicted. The prediction of the wear condition allows intelligent maintenance strategies. This allows residual tool life to be fully utilized, scrap to be reduced and downtime to be calculated. The content of this article is an economic analysis for calculating the payback period of a process monitoring system.

In the forging industry, which is dominated by SMEs, the tool life of forging dies is usually determined on the basis of empirical values and subjective decisions. In order to avoid considerable logistical and economic expenses as a result of unplanned downtimes and die failure, the tool life is often set many times lower and a waste of existing residual tool life is caused. One possibility to determine the remaining tool life of forging tools is a combined measuring method, which is to be developed at the Institut für Integrierte Produktion Hannover (IPH) gGmbH.
