  1. 1. A Study on Abrasive Waterjet Milling

    Författare :Christian Öjmertz; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; discrete AWJ milling; ceramics; industrial application; abrasive waterjet milling;

    Sammanfattning : Abrasive waterjets (AWJ) have in a short time become an indispensable industrial tool for many machining operations involving hard-to-machine materials. In general, the process is used for through-cutting but there is an awakening interest in utilizing the process for three-dimensional machining, or milling. LÄS MER

  3. 2. Strategies for Reducing Vibrations during Milling of Thin-walled Components

    Författare :Bertil Wanner; Cornel Mihai Nicolescu; Thomas Björk; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Milling; vibrations; chatter; stability; prediction; thin-wall; Inconel 718; Manufacturing and materials engineering;

    Sammanfattning : Factors such as environmental requirements and fuel efficiency have pushed aerospace industry to develop reduced-weight engine designs and thereby light-weight and thin-walled components. As component wall thickness gets thinner and the mechanical structures weaker, the structure becomes more sensitive for vibrations during milling operations. LÄS MER

  5. 4. Haptic Milling Simulation in Six Degrees-of-Freedom : With Application to Surgery in Stiff Tissue

    Författare :Magnus G. Eriksson; Jan Wikander; Dwight Meglan; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Surgical simulation; Virtual reality; Haptic feedback; Surgical training; Medical simulators; 3D visualization; Six degrees-of-freedom; Bone milling;

    Sammanfattning : The research presented in this thesis describes a substantial part of the design of a prototypical surgical training simulator. The results are intended to be applied in future simulators used to educate and train surgeons for bone milling operations. LÄS MER

  7. 5. Condition monitoring of machine tools and machining processes using internal sensor signals

    Författare :Jari Repo; Mihai Nicolescu; Dragos Axiente; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; condition monitoring; machine tool; machining process; milling; position encoders; signal analysis; Mechanical engineering; Maskinteknik; Materials science; Manufacturing and materials engineering;

    Sammanfattning : Condition monitoring of critical machine tool components and machining processes is a key factor to increase the availability of the machine tool and achieving a more robust machining process. Failures in the machining process and machine tool components may also have negative effects on the final produced part. LÄS MER
