Influence of Cutting Tool Wear on the Quality of Poplars Veneers

Abstract

Poplar wood is well known as a potential raw material for veneer industry. However, its proportion of tension wood often cause problems on the veneer quality. Therefore, optimization of machining process is required to improve the quality of veneer. This study aims to examine the role of machining factors, especially cutting tool wear on the quality of poplar veneer. The plan of experiments was done by using the Taguchi method with six machining parameter. Peeling process was performed by using the micro lathe. The results showed that cutting tool wear, pressure bar, and temperature of wood give significance influence on surface roughness while pressure bar and cutting speed were important factors on lathe check formation.
