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.

Die nachfolgende Studie ist an der Technischen Hochschule Georg Agricola zu Bochum entstanden. Sie gibt einen Überblick über die Grundlagen, Anwendungen und Möglichkeiten der Werkzeugoptimierung und somit der Standzeiterhöhung mithilfe des Hochpräzisionsbürstens (Flakkotieren) an Mikrotorusfräsern. Ein Abgleich von verschiedenen präparierten und sich im Ausgangszustand befindlichen Mikrofräsern sollen hierbei die Möglichkeiten und Grenzen der Schneidkantenpräparation aufzeigen.   The following study was carried out at the Technical University Georg Agricola in Bochum. It provides an overview of the basics, applications and opportunities for improving tools and thus for increasing tool life with the aid of high-precision brushing (flakkoting) on milling tools for hard milling. Comparing a number of prepared micro milling cutters in their initial state, it demonstrates the opportunities and limits of cutting edge preparation.

Edge Preparation

After the grinding process, the cutting edges of cemented carbide milling tools tend to chipping. Chipping has a strong influence on the tool performance. For this reason, the cutting edges are further prepared. Additionally, a cutting edge rounding has an impact on the wear behavior and the process stability. For the cutting edge preparation of milling tools, magnetic finishing is a promising process. This paper describes the process of magnetic finishing. The influencing parameters, i.e. the process time and the distance between the cutting tool and the magnetic disks, are investigated. Furthermore, the effect of magnetic finishing on the tool life is demonstrated using the example of a milling process with titanium.

One of the decisive factors for the performance of milling tools is the quality of the cutting edge. The latter results from the process control of the individual steps along the tool manufacturing process chain, which generally includes the sintering or pressing of the blanks, grinding, cutting edge preparation, and coating of the tools. However, the targeted and application-specific design of the process steps in terms of high economic efficiency is currently limited by a lack of knowledge regarding the influence of the corresponding process parameters on the resulting cutting edge quality. In addition, there is a lack of suitable parameters that adequately represent the characteristics of the cutting edge microtopography. This publication therefore investigates the influence of manufacturing processes on cutting edge quality and wear behavior of end mills. On this basis, different characterization parameters for the cutting edge quality are derived and evaluated with regard to their ability to predict the wear behavior.

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.

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.
