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 m/min for hardwoods at a 25° cutting angle in planing, and at a 15° angle for softwoods. Key words: Wood, machining properties, planing, shaping, boring, sanding 1. Introduction The wood products industry plays a very important role in the world economy. Wood has traditionally been the basic raw material for the furniture and joinery industries. One of the most important advantages of wood is its easy machinability in contrast to metal and plastic products. However, its nonuniform characteristics within and between species plays a .
