  1. 1. Analysis and direct optimization of cutting tool utilization in CAM

    Detta är en avhandling från Trollhättan : University West

    Författare :Ana Esther Bonilla Hernández; Högskolan Väst.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CAM programming; Material Removal Rate; Tool life; Tool wear; Tool utilization; Cutting data; Lean; Optimization; CIM; Integration IT tools; Manufacturing; Manufacturing and materials engineering; Produktions- och materialteknik; Production Technology; Produktionsteknik;

    Sammanfattning : The search for increased productivity and cost reduction in machining can be interpreted as the desire to increase the material removal rate, MRR, and maximize the cutting tool utilization. The CNC process is complex and involves numerous limitations and parameters, ranging from tolerances to machinability. LÄS MER

  2. 2. Laser welding of boron steels for light-weight vehicle applications

    Detta är en avhandling från Trollhättan : University West

    Författare :Karl Fahlström; Högskolan Väst.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser welding; boron steel; high strength steels; strength reduction; brittle behavior; crack susceptibility; distortions; light-weight; quality; Manufacturing and materials engineering; Produktions- och materialteknik; Production Technology; Produktionsteknik;

    Sammanfattning : Laser beam welding has gained a significant interest during the last two decades. The suitability of the process for high volume production has the possibility to give a strong advantage compared to several other welding methods. However, it is important to have the process in full control since various quality issues may otherwise occur. LÄS MER

  3. 3. Environmental performance requirements in product development : an exploratory study of two development projects

    Detta är en avhandling från Linköping : Linköpings universitet

  4. 4. Multi-Robot Motion Planning Optimisation for Handling Sheet Metal Parts

    Detta är en avhandling från Trollhättan : University West

    Författare :Emile Glorieux; Högskolan Väst.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-robot systems; motion planning; modelling and simulation; optimisation; Production Technology; Produktionsteknik;

    Sammanfattning : Motion planning for robot operations is concerned with path planning and trajectory generation. In multi-robot systems, i.e. with multiple robots operating simultaneously in a shared workspace, the motion planning also needs to coordinate the robots' motions to avoid collisions between them.

  5. 5. Modelling of cathode-plasma interaction in short high-intensity electric arc Application to Gas Tungsten Arc Welding

    Detta är en avhandling från Göteborg : Chalmers University of Technology

    Författare :Alireza Javidi Shirvan; Högskolan Väst.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik; Electric arc discharge; sheath; pre-sheath; Knudsen layer; doped refractory cathode; arc-cathode coupling; Gas Tungsten Arc simulation; OpenFOAM.; electric arc discharge;

    Sammanfattning : In arc welding the quality of the weld is strongly influenced by the thermal history of the workpiece which is itself governed by the electric arc heat source. The models for predicting weld properties thus need a good evaluation of the distribution of the heat input from thearc to the workpiece. LÄS MER
