  1. 1. Comparison of Modified Double Tray Method and 3D scanning i prosthodontics

    University essay from Umeå universitet/Institutionen för odontologi

    Author : Elsa Nermo; Eloïse Rousseau; [2023]
    Keywords : 3D scanning; modified double tray method.;

    Abstract : The purpose of this in vitro study was to investigate and to compare the precision of two different impression techniques for oral prosthetic construction, namely the analogue modified double tray method, and the digital three-dimensional scanning with Trios 3D shape intraoral scanner. The analog method used was a modified double tray method where the tray had been removed to diminish vertical discrepancies in occlusion. READ MORE

  3. 2. Developing an Ar milling process to improve the contact quality to InAs nanowires

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

    Author : Chris Mkolongo; [2023]
    Keywords : InAs nanowires; Argon milling; Technology and Engineering;

    Abstract : The aim of this work was to develop a stable and reproducible argon milling process for InAs nanowires to remove the native oxide layer that increases electrical resistance. This was done by identifying a few milling parameters and studying them in relation to the milling rate of silicon dioxide (SiO2). READ MORE

  4. 3. Evaluation of Refined Tribological Properties of Diamond Coated Cutting Tools Used in Machining of High-Strength Aluminum Alloys : Master thesis report regarding refined frictional & wear behavior of uncoated & CVD diamond coated WC-Co cemented carbide cutting tools used for machining of Al 7xxx alloys.

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Christian Hultman; [2022]
    Keywords : tribology; machining; metal cutting; turning; milling; friction; wear; material transfer; surface technology; tribologi; skärande bearbetning; svarvning; fräsning; friktion; förslitning; nötning; materialöverföring; ytteknologi;

    Abstract : High strength aluminum alloys have for a long time been a popular material utilized in the automotive and aerospace sector due to coveted mechanical properties in terms of weight, strength, fatigue, and corrosion. However, tribological mechanisms such as tribo-film formation and material transfer during the metal cutting manufacturing process of aluminum impose significant reduction of machining and tool-life performance.

  5. 4. Analysis of implementing additive manufacturing for the making of casting patterns

    University essay from Lunds universitet/Industriell Produktion

    Author : Simon Håkansson; [2022]
    Keywords : 3D-printing; additive; manufacturing; polymer; plastic; wood; pattern; casting; molding; vacuum; sand; ABS; milling; turning; Technology and Engineering;

    Abstract : I den här rapporten undersöks möjligheten för att tillverka och använda gjutmodeller tillverkade genom additiv tillverkning, i folkmun kallat 3D-printing. Först görs en grundläggande analys över hur modellerna tillverkas idag och vilka krav som ställs på modellen. READ MORE

  6. 5. Tribological behaviour of CVD diamondcoated tools during machining of highstrength aluminum alloy : Master thesis project on tribological behavior of super hard materials: chemicalvapor deposition diamond (CVD) coated cutting tools and polycrystalline diamond(PCD) cutting tools used in machining of high strength aluminium alloy

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Oskar Lundquist; [2022]
    Keywords : CVD diamond coating; CVD; Aluminum machining; Tool coatings; PCD; diamond coating; diamond; Tribology; Material Science.;

    Abstract : Machining of Aluminum can be complicated due to large amounts of adhesion and diffusion of the aluminum onto the cutting tool, causing effects such as built-up layers and built-up edges. This leads to poor surface finishes and can significantly affect the tool life. READ MORE
