Angesichts steigender Anforderungen an Zerspanwerkzeuge nimmt die Schneidkantenpräparation einen immer größer werdenden Stellenwert ein, da sich so die Standzeit von Zerspanwerkzeugen erhöhen lässt. Die bisher eingesetzten Präparationsverfahren eignen sich meist nur für einfache Verrundungen an der Schneidkante. In umfangreichen Untersuchungen wurde die Eignung von Formschleifprozessen zur Herstellung definierter Schneidkantenmikrogeometrien anhand von Arbeitsergebnissen analysiert.   Due to increasing demands on cutting tools cutting edge preparation has a high priority because it influences the tool life. Current cutting edge preparation processes can only generate simple roundings on the cutting edge. By extensive investigations the suitability of form grinding processes for the production of defined microgeometries on the cutting edge was analysed.

Die Prozesssicherheit beim Mikrofräsen lässt sich mit einer gezielten Schneidkantenverrundung erheblich steigern. Dabei werden durch verschiedene Präparationstechnologien unterschiedliche Geometrien und Einflüsse auf den Fräsprozess erzeugt. Der Fachbeitrag behandelt den Einsatz präparierter Mikrowerkzeuge in Zerspanversuchen, in denen auf die Zerspankräfte, den Verschleiß sowie die Oberflächengüten eingegangen wird.   Process reliability in micro milling can be increased by a defined cutting edge preparation. Different cutting edge preparations cause different effects on tool behavior in the downstream micro milling process. In this paper, the process forces, the tool wear and the surface quality of prepared micro milling tools are characterized in cutting tests.

Dieser Beitrag beschreibt, wie sich die Standzeit von Kreissägeblättern durch Schneidkantenpräparation gezielt beeinflussen lässt. Hierfür wurden zunächst einzelne Segmente aus einem Sägeblatt herausgetrennt und Einzahnproben mit variierenden Schneidenmikrogeometrien mittels Bürstspanen präpariert. Anschließend wurde das Einsatz- und Verschleißverhalten der zuvor hergestellten Proben in einem Kreissäge-Modellversuch untersucht.   This article describes how the service life of circular saw blades can be specifically influenced by cutting edge preparation. For this purpose, individual segments were first cut out of a saw blade. These single-tooth specimens with varying cutting edge microgeometries were prepared by abrasive brushing. Then the usage and wear behavior of the previously produced samples was investigated in a circular saw model test.

The improvement of the microgeometry became a subject of a great interest in cutting tools optimization. This paper approaches the process of cutting edge preparation of solid carbide reamers. It has been analyzed the evolution of cutting edge wear resistance in the material GGG 40 using the scanning electron microscope (SEM). The work also compared the rounded cutting edge reamers realized using wet abrasive jet machining with standard unprepared cutting edge. To obtain different microgeometries were experienced a number of machining strategies, which resulted in four combinations of roundness and forms for the cutting edge. In order to validate the results, the author studied the wear resistance during the reaming tests, the influence of prepared surface of the cutting edge on metallic coating layer adhesion. The final purpose was to determinate the optimal strategy of cutting edge preparation considering the evolution of wear during the reaming process.
