  1. 1. Chip Management in Milling and Drilling of Ductile Cast Iron

    Master-uppsats, Lunds universitet/Industriell Produktion

    Författare :Alexander Jönsson; Giacomo Aliboni; [2023]
    Nyckelord :Chip Carryover; Chip Management; Ductile Cast Iron; Chip Removal; Chip Asportation; Milling; Drilling; Technology and Engineering;

    Sammanfattning : This paper presents a comprehensive cross-functional analysis of machining operations for ductile cast iron components in the automotive industry, focusing on the problem of chip carryover and its impact on downstream processes. The research aims to understand the role of machining and identify the source of the issue, by analyzing different machining sequences and the chips that affect the final product or subsequent production stages.

  3. 2. Cooling Strategy Influence on Temperature in ETD Center

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Oskar Edinger; [2021]
    Nyckelord :Machining; Drilling; Exchangeable tip drill; 316L Stainless steel; Thermocouple; IR Thermography; Skärande bearbetning; Borrning; Löstoppsborr; 316L Rostfritt stål; Termoelement; IR Termografi;

    Sammanfattning : Striving for increased productivity while maintaining hole quality and high process robustness when drilling requires knowledge about the working principles of heat generation, mechanics and a proper cutting fluid that aids in cooling, lubricating and evacuating chips from the cutting zone. If the heat generated in the tool-workpiece and tool-chip interfaces does not exit the cutting zone adequately through the chips, the workpiece material or the redistribution of coolant the hole quality can be impacted negatively and breakdowns may occur which reduces overall productivity.

  4. 3. Rigg för varmextrusion av metallspån

    Kandidat-uppsats, Högskolan i Gävle/Avdelningen för industriell ekonomi, industridesign och maskinteknik

    Författare :Olle Fantenberg Persson; [2020]
    Nyckelord :Extrusion;

    Sammanfattning : Extrusion is a design process where the material is heated and pressed through a metal disc, called a die. The opening through which the material is pressed through forms the material. There are two different types of extrusion: direct and indirect extrusion. Where the difference between them is how the material is pressed through the die. LÄS MER

  5. 4. A Gimbal Stabilizer : Self-stabilizing platform for holding objects horizontally stable

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Maksims Svjatoha; Behnam Yosef Nezhad Arya; [2019]
    Nyckelord :mechatronics; stabilizer; self-stabilizing; feedback control; PID; Arduino; inertial stabilization.; mekatronik; stabilisering; plattform; självstabiliserande; återkoppling; reglerteknik; PID; Arduino.;

    Sammanfattning : This bachelor thesis is about the design and construction of a self-stabilizing platform. The purpose of this system is to balance objects placed upon the platform by keeping the platform level regardless of how the mechanism itself is rotated. Its uses include stabilization of sensors, cameras and vehicle cockpits. LÄS MER

  7. 5. Residual stresses in Ti-6Al-4V from low energy laser repair welding

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Peter Ericson; [2018]
    Nyckelord :Micro laser welding; Low energy welding; Ti-6Al-4V; Ti64; Residual stress; Response Surface Methodology; Repair welding; Welding simulation; Mikrolasersvetsning; Lågenergetisk svetsning; Lågenergisvets; Ti-6Al-4V; Ti64; Restspänningar; Response Surface Methodology; Reparationssvets; Svetssimulering;

    Sammanfattning : Millimeterstora och svårupptäckta defekter kan uppstå internt i stora och komplexa gjutgods av Ti-6Al-4V, ibland går dessa oupptäckta tills detaljen genomgått mekanisk bearbetning och en stor kostnad redan har gått in i den. Dessa defekter och andra industriella olyckshändelser leder till ett behov av additiva reparationsmetoder där den för tillfället rådande metoden är TIG-svetsning. LÄS MER
