Accurate prediction of fractures that occur in a material during forming not only improves quality, but also reduces the amount of material that is discarded. Formability evaluation is generally performed using ductile fracture criteria or experimental forming limit diagrams (FLDs), but these require fracture tests to be conducted beforehand. The authors have established a formability...

Process monitoring in forming technology can serve as a basis for transparent manufacturing and closed-loop control systems. Particularly, sensor systems associated with tool clamping interfaces offer great potential for robust inline process monitoring. However, the direct evaluation of only one sensor or even pure sensor data is hardly sufficient or not possible due to complex...

ABSTRACT
In recent years, one of the main challenges in industry has been obtaining work parameters in real time for later analysis to understand the process better. The purpose is to obtain substantial information about the process for better decision-making, i.e., what happens during manufacturing to...

Sheet metal is an extremely common form of use in broad engineering sectors and represents the main consumption of steel and aluminum in Europe. All production processes where sheet metal is used require cutting operations. Therefore, it is an extremely relevant procedure, common and of great economic importance in material-intensive sectors such as automotive, construction and engineering....

Punching represents one of the most frequently used manufacturing processes in the sheet metal processing industry. Thereby, one of the most important quality criteria for such punching processes constitutes the geometric shape of the cutting surface. High cutting surface qualities are usually characterized by the lowest possible edge draw in, a high clean cut, as well as a small fracture...
