Abstract
Although Papua New Guinea (PNG) has a rich and diverse forest cover, there is limited information on processing characteristics for plantations and regrowth forests available. Consequently, the PNG timber processing industry is restricted to a few species, producing low-quality products, which limits opportunities for the processors. Sound knowledge of machining characteristics based on some systematic methods has been identified as essential for assessing the ability in processing raw material into appearance products. Therefore, a testing program was conducted to assess the planing characteristics and most common causes for planing degrade of 25 species sourced from the Morobe and West New Britain provinces, PNG. A total of 18 wood species proved to machine very well with more than 90% of assessed boards being graded either “excellent and requiring very light sanding” or “good and requiring light sanding”. Eight species from this group obtained a perfect score, i.e. requiring very light sanding.
