Oscillating forming processes play a special role in forming technology. The forming operation is divided into individual strokes by the incremental process. In the case of oscillating gear pressing, this ensures re-lubrication in the forming area, which leads to a force reduction of up to 40% (compared to the classic stroke).
At present, the incremental strokes are always the same length. Since the loads vary during forming, it makes sense to perform the strokes force-controlled. For this purpose, a press was equipped with a force-displacement feedback for incremental processes.
In a master thesis, the influences of the load-dependent incremental stroke on the forming process are to be examined and a model for describing the stroke progression as a function of the load is to be proposed.
The work packages will be defined together with the student! The student's interests (e.g. simulation) will be considered!
