Recent progress in research on the cutting processes of wood. A review COST Action E35 2004–2008: Wood machining – micromechanics and fracture

Abstract Recent progress in research on the cutting processes of wood is presented, particularly in regard to new methods of accomplishing an increase in volume recovery by sawmills. The suitability of modern fracture mechanics was demonstrated for the estimation of the cutting power for saws in which kerfs are different from saws used in cutting tests, and whereby the data of sawn material – such as the specific work of surface formation (toughness) and the shear yield stress – were determined. Cutting tests were carried out on the modern frame sawing machine (sash gang saw) for narrow-kerf sawing with the hybrid dynamically balanced driving system and elliptical teeth trajectory movement.

Examination of tools of different materials edge geometry for MDF milling

AbstractMost of the investigations directed to find the relation between tool wear and the wood-based panel characteristics concern particleboard cutting. The goal of this paper was to characterize the optimal edge geometry, in case of wear, when milling the medium-density fibreboard, for blades produced from different materials. ZusammenfassungDie meisten Untersuchungen über den Zusammenhang von Werkzeugverschleiß und den Eigenschaften von Holzwerkstoffplatten beziehen sich auf die Bearbeitung von Spanplatten. Ziel dieser Studie war es, die optimaleSchneidengeometrie unterschiedlicher Sägeblattmaterialien für das Fräsen von MDF in Abhängigkeit vom Werkzeugverschleiß zu bestimmen.
