Influence of Chrysoporthe deuterocubensis Canker Disease on the Machining Properties of Eucalyptus urograndis

This study assessed the machining properties of 11-year-old Eucalyptus urophylla × E. grandis, known as urograndis wood, that was infected by stem canker disease, Chrysoporthe deuterocubensis. Instead being discarded directly, aimed to explore possibility trees used in other applications such furniture. Sawing, planing, and boring well surface roughness healthy were evaluated. The samples collected from classified according severity attack: (class 1), moderately 2), severely 3), very 4). Prior sawing, boring, prepared ASTM D 1666-11 Standard Test Methods for Conducting Machining Tests Wood Wood-Base Materials. All sawn, planed, bored evaluated their respective quality. machined also assessed. Overall, different infection has good ranging Grade I III. Fuzzy grain, chip mark, tear out are most commonly seen physical defects. As roughness, have lower compared trees, which indicates a better findings this suggested can still be many applications. results will provide us with knowledge about performance disease-infected wood its possibilities raw material products industry.
