    Sammanfattning : Within the manufacturing of metallic components, machining plays an important role and is of vital significance to ensure process reliability. From a cutting tool design perspective, physics-based numerical modeling that can predict chip morphology is highly necessary to design tool macro geometry. LÄS MER

  3. 2. Influence of Microstructure on Chip Formation - Machining Aero Engine Alloys

    Författare :Stefan Cedergren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Superalloy; Alloy 718; Ti-6Al-4V; Inconel 718; segmented chip; shear-localization;

    Sammanfattning : Aero engine materials such as nickel-iron and titanium based alloys are known to be very difficult to machine. They are also known to produce shear-localized chips; a type of chip which is associated with both an increase of the tool wear and the vibration levels during machining. LÄS MER

  4. 3. Influence of Material Variations on Machinability - Machining Difficult-to-Machine Alloys

    Författare :Stefan Cedergren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alloy 718; Superalloys; Ti-6Al-4V; segmented chip; 316L;

    Sammanfattning : The aim of this study is to investigate the effect of work material variations on machinability. Improved knowledge in this respect supports the development of sustainable production both from resource and economical points of view.The properties of work materials vary greatly depending on how they were manufactured.

  5. 4. Influence of Microstructure in Machining of Nickel and Nickel-Iron Based Alloys

    Författare :Stefan Olovsjö; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wear mechanisms; Simulation; Tool wear; Burr; Meta-modelling; Inconel 718; Metal cutting; Superalloy; Waspaloy; Chip morphology; Notch wear; Alloy 718; JMatPro;

    Sammanfattning : Superalloys are used in applications such as turbines, steam power plants and nuclear power systems in components that require good high temperature properties and/or corrosion resistance. They are classified as difficult-to-cut materials and hence, from a sustainable production point of view, tool wear and tool life are major factors when machining these alloys. LÄS MER

  7. 5. Study on electroabsorption modulators and grating couplers for optical interconnects

    Författare :Yongbo Tang; Urban Westergren; Dries Van Thourhout; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Photonic integrated circuit; optical interconnect; transmission line; traveling-wave; electro-absorption modulator; hybrid silicon evanescent platform; grating coupler; vertical coupling scheme; optical antenna; lag effect; polarization beam splitter; Photonics; Fotonik; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Sammanfattning : Decades of efforts have pushed the replacement of electrical interconnects by optical links to the interconnects between computers, racks and circuit boards. It may be expected that optical solutions will further be used for inter-chip and intra-chip interconnects with potential benefits in bandwidth, capacity, delay, power consumption and crosstalk.
