  1. 1. Mechanical and tribological characterization of additive manufactured Co-alloyed tool steels aimed for cutting tool bodies

    Magister-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Jijesh Rajan; [2022]
    Nyckelord :Maraging steels; Selective laser melting; microstructure; wear; Modified 18Ni300; Osprey MAR;

    Sammanfattning : A drill tool body operates under tough cutting conditions where it is subjected to severe rubbing at the drill flute margin by the sliding chips. The tool wear caused by the contact stresses of the high-speed sliding chips is one of the common damage mechanisms observed in drill tool bodies. LÄS MER

  3. 2. Mechanical and tribological characterization of additivemanufactured Co-free tool steels aimed for cutting tool bodies

    Master-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Mayur Mane; [2021]

    Sammanfattning : Additive manufacturing (AM) is an emerging and interesting technology that enables some of theproduct development projects (PDPs) to produce products that have mechanical and tribologicalproperties comparable to products that are conventionally manufactured. Selective laser melting(SLM) is an additive manufacturing technology that is predominantly used for the production of metalbased components (i. LÄS MER

  4. 3. Chip Breaking Optimization During Turning Shoulder

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

    Författare :XINYI YANG; [2017]
    Nyckelord :chip breaking; chip breaker; tool path; OEE; spånbrytning; spånbrytare; verktygsväg; OEE;

    Sammanfattning : Poor chip breaking is a normal problem in the field of machining in many manufacturing plants. The researches on chip control has started from the early 1900s, it has developed for more than one hundred years and researchers are still working on it to establish a ‘total’ chip control system.

  5. 4. MIMO Multiplierless FIR System

    Master-uppsats, Institutionen för systemteknik

    Författare :Muhammad Imran; Khursheed Khursheed; [2009]
    Nyckelord :MIMO Multiplierless FIR system; Generalised MCM Algorithm; Multiplierless Multiplication;

    Sammanfattning : The main issue in this thesis is to minimize the number of operations and the energy consumption per operation for the computation (arithmetic operation) part of DSP circuits, such as Finite Impulse Response Filters (FIR), Discrete Cosine Transform (DCT), and Discrete Fourier Transform (DFT) etc. More specific, the focus is on the elimination of most frequent common sub-expression (CSE) in binary, Canonic Sign Digit (CSD), Twos Complement or Sign Digit representation of the coefficients of non-recursive multiple input multiple output (MIMO)  FIR system , which can be realized using shift-and-add based operations only.
