During this funded research and development project, QASS is going to develop a new measuring device to determine the level of wear of shearing tools during the process.
Up to now, no method of detecting the level of wear during the process is known. A direct measurement is impossible, because of the high number of strokes and inaccessibility of the process. This is why we’re going to use the indirect measurement method of acoustic emission to determine wear.
The focus of this study lies upon correlating the wear of the shearing tool with acoustic emission signals. Partner of QASS is the Institute for Metal Forming Technology (IFU) at the University of Stuttgart. QASS is going to analyse the process and produce the measuring device, IFU is going to analyze the process and the tools. The plan is to quantify the level of wear by analyzing the acoustic emission signals in a three dimensional way.
This will make the way free for saving money by detecting worn-off tools just in time – and by this avoiding reject.
The project ran from June 1st, 2014, to July 31st, 2015.
