  2. 1. Adaptive Active Control of Machine-Tool Vibration in a Lathe - Analysis and Experiments

    Author : Lars Håkansson; Industriell Produktion; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materiallära; Material technology; Metal Cutting; Lathe; Tool Vibration; Active Control; Adaptive Signal Processing; materialteknik;

    Abstract : In the turning operation the relative dynamic motion between cutting tool and workpiece, or vibration, is a frequent problem, which affects the result of the machining, and in particular, the surface finish. Tool life is also influenced by vibration. READ MORE

  4. 2. Quality Aspects of Sliced Oak Lamellae in Development of Engineered Wood Flooring

    Author : Victor Grubîi; Jimmy Johansson; Alexander Pfriem; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood slicing multi-layered flooring surface-checking climate test. hardwoods processing slicing lathe checks digital image correlation DIC image processing veneers; Forestry and Wood Technology; Skog och träteknik;

    Abstract : Valuable hardwoods, such as oak, although renewable, present limitations in product realisation in terms of their cost and availability, often attributed to production waste and sub-optimal product design factors. The slicing technique facilitates the production of thin wood lamellae, minimising waste and ensuring optimal material conversion. READ MORE

  5. 3. Vibrations in Metal Cutting : Measurement, Analysis and Reduction

    Author : Linus Pettersson; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Vibration and noise in metal cutting are ubiquitous problems in the workshop. The turning operation is one kind of metal cutting that exhibits vibration related problems. Today the industry aims at smaller tolerances in surface finish. Harder regulations in terms of the noise levels in the operator environment are also central. READ MORE

  6. 4. Laminated Veneer Products : Shape Stability and Effect of Enhanced Formability on Bond-Line Strength

    Author : Lars Blomqvist; Jimmy Johansson; Hans Petersson; Dick Sandberg; Peter Niemz; Linnéuniversitetet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Forestry and Wood Technology; Skog och träteknik;

    Abstract : This thesis concerns two aspects of the manufacture of laminated veneer products (LVPs). The first aspect is related to the possible improvement of the shape stability of LVPs, and the second has its starting point in the modification of the veneer for enhanced formability as well as the question of whether and how these modifications affect the bond-line strength.

  7. 5. Improving Machining System Performance through designed-in Damping : Modelling, Analysis and Design Solutions

    Author : Lorenzo Daghini; Cornel Mihai Nicolescu; Miroslav Píška; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machining performance; Cutting stability; Passive damping; High Damping Interface; Boring bar; Turret; SRA - Production; SRA - Produktion;

    Abstract : With advances in material technology, allowing, for instance, engines to withstand higher combustion pressure and consequently improving performance, comes challenges to productivity. These materials are, in fact, more difficult to machine with regards to tool wear and especially machine tool stability. READ MORE
