  3. 3. Circular Manufacturing Systems : A development framework with analysis methods and tools for implementation

    Författare :Farazee M A Asif; Amir Rashid; Peter Hopkinson; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Circular economy; circular manufacturing systems; resource conservative manufacturing; ResCoM; system dynamics; Production Engineering; Industriell produktion;

    Sammanfattning : The society today lives on the philosophy of ‘take-make-use-dispose.’ In the long run, this is not sustainable as the natural resources and the waste carrying capacity of the earth are limited. Therefore, it is essential to reduce dependency on the natural resources by decoupling the growth from the consumption. LÄS MER

  4. 4. Model-Based Investigation of Machining Systems Characteristics : Static and Dynamic Stability Analysis

    Författare :Andreas Archenti; Mihai Nicolescu; Amir Rashid; KTH; []
    Nyckelord :Machining systems; modelling; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The increasing demands for precision and efficiency in machining call for new control strategies for machining systems based on the identification of static and dynamic characteristics under operational conditions. By considering the machining system as a closed-loop system consisting of a machine tool structure and a machining process, the join system characteristics can be analyzed. LÄS MER

  5. 5. Controlling the dynamic characteristics of machining systems through consciously designed joint interfaces

    Författare :Constantinos Frangoudis; Cornel Mihai Nicolescu; Amir Rashid; Bulent Tasdelent; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Production; machine tool; machining system control; joint interfaces; JIM; stiffness; damping; vibrations; machining process; milling; turning; deflections; accuracy; dynamic response;

    Sammanfattning : The precision of machining systems is ever increasing in order to keep up with components’ accuracy requirements. At the same time product variants areincreasing and order quantities are decreasing, which introduces high demands on the capability of machining systems. LÄS MER
