Abstract
The quality of wood surfaces after different kinds of machining processes is a property of great importance for the wood processing industries. Present work is a study, whose objective was to evaluate different non-contact methods, for measurement of the quality of the wood surfaces by correlating them with stylus tracing. A number of Scots Pine samples were prepared by different kinds of wood machining processing. Surface roughness measurements were performed, utilizing two optical noncontact methods. The results indicate that the laser scan method can measure surface roughness on sawn wood with a sufficient degree of accuracy.
Zusammenfassung
Die Qualität von Holzoberflächen nach unterschiedlicher maschineller Bearbeitung ist eine wichtige Kenngröße in der holzverarbeitenden Industrie. In der vorliegenden Arbeit werden verschiedene zerstörungsfreie Methoden verglichen, mit denen die Oberflächengüte von bearbeitetem Holz gemessen werden kann. Alle Verfahren werden korreliert mit dem mechanischen Tastschnittverfahren. Mehrere Kiefernholzproben wurden mit unterschiedlichen Holzbearbitungsmaschinen hergestellt. Die Oberflächen-Rauhigkeit wurde mit zwei optischen Methoden berührungsfrei gemessen. Es zeigt sich, daß die Laser-Scan-Methode gesägte Holzoberflächen mit hinreichender Genauigkeit charakterisieren kann.
