Abstract
Peripheral machining of Rubberwood LVL and solid Rubberwood were carried out on a computer numerical control router, using cemented tungsten carbide cutters. The cutter wear rate and power consumption showed similar patterns of increment. Rubberwood LVL was found to be four times as abrasive as solid Rubberwood, and a combination of wear mechanisms were involved in contrast, to abrasion which was the predominant mechanism when machining solid Rubberwood. The use of a simple wear model based on the Taylor’s tool life equation has enabled the total tool wear to be quantified. This information can be expanded into useful production data for the Rubberwood based high-volume Furniture manufacturing industry.
Zusammenfassung
Furnierschichtholz und Massivholz vonHevea brasiliensis wurden mit einer numerisch gesteuerten Oberfräse bearbeitet. Die Schneidwerkzeuge bestanden aus Wolframcarbid. Werkzeugabnützung und Energieverbrauch zeigten jeweils ähnliche Charakteristik. Furnierschichtholz war jedoch viermal aggressiver als Massivholz. Zudem liegt über das Abschleifen hinaus eine Kombination von Abnützungsmechanismen vor, von denen der Abriebverschleiß beim Bearbeiten von Massivholz überwiegt. Mit Hilfe eines einfachen Modells auf der Grundlage der Taylor-Gleichung konnte der gesamt Werkzeugverschleiß quantifiziert werden. Diese Informationen können weitergeführt werden zur Verwendung bei der Großproduktion von Möbeln ausHevea brasiliensis.
