  1. 1. A Study on Abrasive Waterjet Milling

    Författare :Christian Öjmertz; Chalmers University of Technology; []
    Nyckelord :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

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

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

    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

  4. 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 :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

  5. 5. Process-induced disorder of pharmaceutical materials : Mechanisms and quantification of disorder

    Författare :Samaneh Pazesh; Göran Alderborn; Jonas Berggren; Niklas Sandler; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Milling; Comminution; Powder flow; Amorphisation; Raman spectroscopy; Atomic force microscopy; Plastic stiffness; Elastic stiffness; Pharmaceutical Science; Farmaceutisk vetenskap;

    Sammanfattning : One of the most important prerequisites in the drug development is to attain a reproducible and robust product in terms of its nature, and its chemical and physical properties. This can be challenging, since the crystalline form of drugs and excipients can be directly transformed into the amorphous one during normal pharmaceutical processing, referred to as process-induced amorphisation or process-induced disorder.
