摘要

The aim of this study is to determine the wastage rate that occurs during the production process from logs to timbers and from timber to final production of massive wood material. %26lt;br%26gt;The difference between the measured total volume of scotch and black pine logs and the measured volume of timbers produced is called as %26quot;log-timber wastage%26quot;. Similarly, the difference between the volumes of the final scotch pine and beech timbers productions is called as %26quot;timber-final product wastage%26quot;. %26lt;br%26gt;In this study, mean wastage rate was found 37.4 % for 33 logs with a mean diameter of 36.9 cm. The wastage rate was also found 30% for production of flushdoors frames and 46 % for production of massive wooden frames. %26lt;br%26gt;The results were compared with both national and international studies. The use of computer aided manufacturing instead of conventional production machines to manufacture massive wood materials would reduce the wastage rate.
