  5. 4. High Precision Micro-Grinding of Advanced Materials

    Författare :Mohammadali Kadivar; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ceramic; Additive manufacturing; Laser-assisted micro-grinding; Modeling; Surface integrity; Titanium; Micro-grinding; Process efficiency;

    Sammanfattning : The aim of this thesis is to advance a fundamental understanding of process mechanics and surface integrity in micro-grinding of advanced materials, such as additively and conventionally manufactured titanium and engineering ceramic. Grinding forces and specific grinding energy were chosen as the two most important indicators to investigate the process. LÄS MER

  7. 5. Micro-grinding of titanium

    Författare :Mohammadali Kadivar; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dressing; grinding; tool topography.; modelling; Micro machining;

    Sammanfattning : Titanium and its alloys are difficult-to-cut materials, commonly used in several application fields, such as: medicine, aerospace, automotive and turbine manufacturing due to their biocompatibility, corrosion resistance, excellent mechanical and thermal properties, and light weight. However, its machining is associated with several difficulties, such as high tool wear, low surface quality, high cutting forces and high costs. LÄS MER
