A Novel Test Method to Determine the Wear Resistance of Agricultural Cutting Tools with an Analyzing Method Based on an Ellipse-Fit Algorithm

  • Cutting belongs to the essential techniques in many fields of application in agricultural engineering. 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 wearCutting belongs to the essential techniques in many fields of application in agricultural engineering.

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 bladeshow moreshow less
