  2. 6. Adhesion to machined and laser ablated wood surfaces

    Author : Micael Stehr; KTH; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; ablation; adhesion; checks; coating; cracks; excimer laser; gluing; IR laser; mechanical machining; mechanical weak boundary layer; microscopy; notched specimens; pine; planing; sample preparation; sawing; scanning electronmicroscopy; spruce; tip-cracks; UV laser; weak boundary layer; wood;

    Abstract : This thesis is a contribution to the R&D-program ValueActivation at KTH,Division of Wood Technology and Processingand containsfive papers related to the evaluation and development ofmachining techniques (mechanical and irradiation treatments)whereby weak boundaries at the wood surfaces in the form of(mechanical) weak boundary layers and (micro) cracks due tomechanical treatment can be avoided.The first paper describes the development of a method–using a UV laser–to study the mechanically weakenedboundaries.

  5. 8. Characterization of sawlogs using industrial X-ray and 3D scanning

    Author : Johan Skog; Olav Höjbö; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

    Abstract : In the Nordic countries, sawlogs are typically sorted upon arrival at the sawmill based on species and dimension. By processing batches of logs with similar size, the sawing process becomes more efficient; the need to change sawing pattern between individual logs is reduced, and the handling of sawn goods is simplified, since the number of different dimensions produced simultaneously decreases.

  6. 9. Monitoring Single Tooth Cutting Forces in Wood Bandsawing

    Author : Vanessa Meulenberg; Dick Sandberg; Daniel Chuchala; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Science and Engineering;

    Abstract : For economic and environmental benefits, sawmills can reduce their waste by sawing with thinner bandsaw blades. When altering the cutting tooth geometry, it is vital to monitor the sawing process in realistic wood conditions such as frozen (green), non-frozen (green) and dried. READ MORE

  7. 10. Machining properties of wood : Tool wear, cutting force and tensioning of blades

    Author : Luis Cristovao; Frieder Scholz; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

    Abstract : Cutting processes, in general, and wood cutting processes, in particular, are complex to explain and describe with many influencing factors. Wood, in contrast to man-made fabricated materials, is not a homogenous and distinct material, but a multifaceted and nonhomogeneous biological material. READ MORE
