  1. 1. Metamodelling of a Finite Element Analysis of a Drilling Process with Replaceable Inserts

    Magister-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Samy Akrouh Ettaghadouini; [2019]
    Nyckelord :drilling; speed; feed; CAD; FEM; simulations; metamodel; neural network; optimization;

    Sammanfattning : The aim of this project is to create a metamodel from a drilling tool with replaceable inserts from FEA of the machining process using MATLAB and ABAQUS. This report contains research in drilling and in metamodeling using neural networks and the work from the design of the CAD, through FEA and simulations, to the metamodeling, excluding the optimization.

    Nyckelord :;

    Sammanfattning : This report constitutes the result of a master thesis that was composed at Presetting- and Sharpening at Scanias engine department in Södertälje. The department works as a service organisation for the production lines and its purpose is to maintain the right quality on tools within machining. LÄS MER

  3. 3. Design and construction of a contactless excitation and response measurement system

    Master-uppsats, KTH/Industriell produktion

    Författare :Johan Westlund; [2019]
    Nyckelord :Rotor dynamic; Electromagnet; Contactless excitation; LabVIEW; Measurement instruments; Force control; CERS; Rotordynamik; Elektromagnet; Kontaktlös exitation; LabVIEW; Kraftkontroll; CERS;

    Sammanfattning : Manufacturing industry works on Overall Equipment Effectiveness (OEE) to increase the yield and speed of machining. A good knowledge of the machine properties is important to increase the speed while still maintaining stable cutting with low tool usage. LÄS MER

  4. 4. Design of High Performance Flanges and its Influence on Manufacturing Costs, Structural Performance and Weight

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Joaquin Alcocer Bonifaz; [2019]
    Nyckelord :manufacturing cost modeling; computer simulated experiments; bolted flanges; aero engines; complexity theory; : tillverkningskostnadsmodellering; datorsimulerade experiment; skruvförbandsflänsar; flygmotorer; komplexitetsteori;

    Sammanfattning : This project attempts to research the manufacturing cost, with an emphasis on machining, of high performance flanges for Turbine Rear Structure (TRS) applications, as well as the tradeoffs with structural performance and weight. A combination of traditional cost modelling techniques from the literature, as well as, the non-conventional manufacturing complexity index, as cost indicator are implemented. LÄS MER

  5. 5. Effect of Beam Scan Length on Microstructure Characteristics of EBM Manufactured Alloy 718

    Master-uppsats, KTH/Materialvetenskap

    Författare :Bengt Gustavsson; [2018]
    Nyckelord :EBM; Electron Beam Melting; Alloy718; AM; Additive Manufacturing;

    Sammanfattning : Additive Manufacturing (AM) as a method is on the rise and allow for a high freedom to create unique shapes without being limited by conventional machining methods. The Electron Beam Melting method, developed by Arcam AB in Mölndal, Sweden, use Powder Bed Fusion together with an electron beam and at an elevated temperature (+1000ºC) to lower stress due to thermal gradients.
