2. 1. SAWING STRATEGIES FOR TROPICAL HARDWOOD SPECIES : Simulation studies based on industrial conditions of Mozambique

   Author : Pedro Ah Shenga; Dick Sandberg; Olof Broman; Mats Nylinder; Luleå tekniska universitet; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sawing strategies; tropical hardwood species; simulation; volume yield; log grading; umbila; jambirre; Träteknik; Wood Science and Engineering;

   Abstract : The harvesting of Mozambique tropical hardwood species is considerable higher than the natural regrowth in the forest and the stock is decreasing drastically. Therefore, it is important to improve the material recovery when the wood is refined (i.e., in sawing and further refinement to products such as joineries, furniture etc. READ MORE

4. 2. Computed tomography of sawlogs : knot detection and sawing optimization

   Author : Erik Johansson; Luleå tekniska universitet; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

   Abstract : Branches on trees introduce defects on sawn timber called knots. By scanning sawlogs using computed tomography, knots can be detected and accounted for so that the sawing process can be optimized with respect to outgoing product value. READ MORE

5. 3. Process control and production strategies in the sawmill industry

   Author : Anders Berglund; Luleå tekniska universitet; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

   Abstract : The sawmill process itself is not complicated. What makes it complex is thediversity of the raw material, the logs that are processed in the sawmill, and thedivergent production with many different end products. In the sawmill variousnumber of measurement and scanning equipments are installed. READ MORE

6. 4. Integrating the bucking operation with production control in sawmilling

   Author : Urban Nordmark; Luleå tekniska universitet; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

   Abstract : There is an ongoing shift in production strategy in the sawmill industry in Scandinavia from bulk production of standard grades towards customer- oriented production of well-defined products. The bucking operation places limits on the timber that can be sawn from the logs. Thus, it is important to be able to control the bucking process. READ MORE

7. 5. How planing affects warp

   Author : Ann Axelsson; Luleå tekniska universitet; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

   Abstract : Although planers and wood machining researchers have been around a long time, the interactions between planks and planers have been neglected in basic research. With a solid understanding of the movements of planks during planing, planers and planing strategies can be developed to reduce waste and improve the value yield. READ MORE
