  1. 1. Mechanical Load Identification for Spontaneous Tool Failure Monitoring

    Författare :Jinming Zhou; Industriell Produktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materiallära; Material technology; Monitoring; Cutting force; Identification; Cutting; Manufacturing; materialteknik;

    Sammanfattning : The problem of spontaneous cutting tool failure, such as tool chipping and breakage, is becoming more and more important in the manufacturing technology. The sponataneous tool failure is usually associated with the stresses subjected on the tool during a metal cutting process. LÄS MER

  3. 2. Theoretical and experimental studies of a single tooth milling process

    Författare :Mathias Werner; Cornel Mihai Nicolescu; Lars Nyborg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hobbing; single tooth milling test; TiN; High speed Steel HSS ; wear mechanisms; cutting force; cutting edge preparation; tool surface preparation; FEM cutting model;

    Sammanfattning : The industrial development of metal cutting processes in gear manufacturing aims at continuously increasing productivity, including increased tool reliability. Basically, the parameters that have an influence on the cutting processes should be known and possible to control.Gear manufacturing is highly important for the automotive industry. LÄS MER

  4. 3. Machining properties of wood : Tool wear, cutting force and tensioning of blades

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

    Sammanfattning : 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. LÄS MER

  5. 4. Numerical Modelling and Analysis of Orthogonal Metal Cutting

    Författare :Mathias Agmell; Industriell Produktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metal Cutting; Finite Element Method; Deformation Zones; Sub-surface Deformation; Tool Stress; Inverse Analysis; Kalman Filter; Minimum Chip Thickness;

    Sammanfattning : Most components in use in our society have undergone a machining process at some stage within its manufacturing cycle. As a result, the economics of the machining process plays an important role in the manufacturing costs. LÄS MER

  7. 5. On the wood chipping process : a study on basic mechanisms in order to optimize chip properties for pulping

    Författare :Lisbeth Hellström; Torbjörn Carlberg; Per Engstrand; Sören Östlund; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood chipping; Chip formation; Digital Speckle Photography; Friction; Fracture Processes; Analytical model; Laboratory Wood Chipper; Force Measurement; Vibration Synthesis; Energy Efficiency; Chip Damage; TMP; CTMP; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Sammanfattning : In both the chemical and mechanical pulping process, the logs are cut into wood chips by a disc chipper before fibre separation. To make the wood chipping process more efficient, one have to investigate in detail the coupling between process parameters and the quality of the chips. LÄS MER
