Abstract

This study, conducted in Iran, investigated the waste from common LOG sawing methods and proposed a new sawing method. The older methods were implemented due to the difficulties of carrying LOGs out of the forest. Since the development of SAWMILLs and forest harvesting plans, it would seem necessary to change these old methods. The dimensions of wood products were collected to calculate the waste of old sawing methods. The computer software, Autocad 14, was used to simulate a sawing based on old sizes and NOMINAL SIZES and then the volumes of wood products were calculated to estimate the yields for old methods and new methods. The yields of two old sawing methods, double taper sawing and SQUARE SAWING, were respectively estimated at 60.6% and 51.9%. The waste of re-sawing to manufacture wood products was estimated at 60% so that the total yield of sawing and re-sawing was reduced to 33.6%. In the new method, based on reverse engineering nominal, sizes of wet LUMBER thickness were estimated between 1.4 cm and 6.7 cm by adding contraction and sanding factors to final dimensions of the wood products. After sawing LOGs to a nominal thickness and producing LUMBER with a nominal width between 1.4 cm and 21.9 cm, the yield of sawing to manufacture wood products with a nominal dimension was estimated at 75.3%, so this new method is recommended as a best choice with the ability to increase yield up to 41.6%.
