Kurzbeschreibung (Abstract)
As a result of the cutting impact, shear cutting processes initiate intensive vibrations in cutting pressesand tools. With the aim to improve the press accuracy and tool lifetime, damping systems for reducingthe press vibration are state of the art. However, only small attention is given to the tool vibration. Dueto its mounting condition in a high-speed press, the lower tool can vibrate like a bending plate. Theamplitude of the tool displacement depends on the clamping situation of the plate edges. Moreover, thedisplacement amplitude correlates with the tool wear. Against this background, it is possible to reduce thewear of a shear cutting tool by systematic design of its clamping situation. In this paper, a methodology formodelling the dynamic behavior of the tool is given. This approach allows a systematic design of the toolclamping situation with the objective to minimize the vibration and thereby the tool wear. Furthermore,the effect of the clamping situation on different process and tool parameters is given by experimentalinvestigations.
