Some machining properties of 4 wood species grown in Turkey

Abstract

Determining wood machining properties and defining convenient usage areas for native wood species is important for evaluating surface quality. Wood machining is a performance criterion indicated after planing, shaping, turning, mortising, boring, and sanding. This study selected 2 softwood species (European black pine and cedar of Lebanon) as well as 2 hardwood species (sessile oak and black poplar), which are commonly used and grown in Turkey. Preparation of samples and machining were carried out according to the 2004 ASTM D 1666 standards for determining machining properties. Sessile oak (Quercus petraea) had an excellent performance in all machining processes. Black poplar (Populus nigra L.) yielded the lowest results for the sanding test. A perfect surface quality was obtained with a feed rate of 8.6 m/min for hardwoods at a 25° cutting angle in planing, and at a 15° angle for softwoods.
