Study of Deroulability in 14 Cultivars of Poplar: Analysis Cutting Force and Lathe Checks of Veneer in Micro-Lathe

Abstract

Poplar is well known for its large wood production. Through this work, the objective of this study seeks to identify the qualities of new cultivars of poplar and classify these new cultivars in a reference quality poplar wood (by evaluating the lathe check phenomenon and measurement of cutting forces in micro-lathe). The 42 disks of 14 cultivars and three stations were conducted in 3 mm for two types of veneer, "heartwood" and "sapwood". The 14 cultivars are concerned from cultivars currently on the market of plant poplar. The micro-lathe was used to measure cutting forces. Veneer of peeling process in micro-lathe was observed using a device called SMOF for systematic and objective analysis of lathe check in the veneer. The result is shown that there no significant effect of the radial position (heartwood and sapwood) and cultivar on the cutting force (Xc/force knife vertical, Yc/force knife horizontal, Xb/force bar vertical, and Yb/force bar horizontal), depth and percentage of lathe check.
