These knives are therefore exposed to high levels of wear and tear, and will also be ofen changed because of loss of material by bad cutting quality. Thatn is why it is interesting to save costs during manufacturing in spite of a correspondingly long service life. This research records the current manufacturing quality of the mower blades and examines how they behave in comparison. Based on the obtained results, further decisions on the methods, procedures and ways of extending the life of the disc mower blades should be proposed. For the investigations, a test bench based on a wear pot was used. The wear that occurs on the blade is determined using several parameters and compared accordingly. The parameters of the test setup determined as a result of the test can be used for further studies of wear resistance. N2 - Bei der Grünfutterernte in der Landwirtschaft werden häufig Scheibenmähwerke eingesetzt, um einen hohen Durchsatz zu erzielen. Die dabei eingesetzten Messer sind einem hohen Verschleiß ausgesetzt und werden häufig wegen Verschleiß gewechselt, was sich in einer schlechten Schnittqualität widerspiegelt. Daher ist es interessant, bereits im Produktionsprozess Kosten einzusparen, ohne dabei die Lebensdauer der Messer zu beeinträchtigen. Diese Studie erfasst die aktuelle Fertigungsqualität von Mähmessern und untersucht, wie sie sich im Vergleich verhalten. Anhand der Ergebnisse sollen weitere Entscheidungen über Methoden, Verfahren und Wege zur Verlängerung der Lebensdauer von Rotorklingen vorgeschlagen werden. Für die Untersuchungen wurde ein Prüfstand auf der Basis des Verschleißtopfverfahrens verwendet. Der am Messer auftretende Verschleiß wird anhand mehrerer Parameter ermittelt und entsprechend verglichen. Die aus den Untersuchungen gewonnenen Parameter können für weiterführende Verschleißuntersuchungen genutzt werden.

Cutting tools in agricultureare exposed to a high amount of abrasive wear and impact stress. Increasing the wear resistance of cuttings tools has a highsignificance for the efficiency and profitability of agricultural machinery. Blunt and deformed blades decrease the energy efficiencyand the cutting quality. Blade failures cause machine breakdowns and increase labor and material costs. To enable a consistent andsystematic optimization of the blades, a suitable testing method is necessary. Conventional field tests do not provide comparableand repeatable results. Therefore, a test method developed at the FMDauto in cooperation with the Ennepetaler Schneid- undM¨ahtechnik (ESM) GmbH & Co. KG is presented. The test bench provides standardized and repeatable conditions with a similarwear pattern which is found during field operations. One of the remaining challenges is a clear wear characterization. Existinganalyzing methods do not consider the energy efficiency and do not determine the edge holding property clearly. In this paper, anew analyzing method based on an ellipse-fit method is introduced to rate the geometrical shape of the cutting edge and examinethe wear resistance of different blade Y1 - 2015 U6 - https://doi.org/10.1155/2015/548238 SN - 2356-6108 N1 - This Conference Paper is based on a presentation given by Hunn Sim at “European Symposium on Friction, Wear, and WearProtection” held from 6 May 2014 to 8 May 2014 in Karlsruhe, Germany VL - 2015 SP - 1 EP - 6 PB - Wiley ER - TY - CHAP A1 - Gaida, Philipp A1 - Jahr, Andreas A1 - Weinberg, Kerstin ED - Dłużewsk, Paweł ED - Jurczak, Grzegorz ED - Young, Toby D.
