  1. 16. Methods for improving performance of process planning for CNC machining : an approach based on surveys and analytical models

    Författare :Staffan Anderberg; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process planning; CNC machining; metal cutting; performance; process capability; environment; energy; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : Process planning as an enabler of competiveness is often overlooked, but being one of the principal function in the product realisation flow it holds a key role by combining both product and production requirements into a production concept with respect to the current manufacturing system. As such the capability of process planning to a large extent dictates production cost, lead times, product quality etc. LÄS MER

  3. 17. Condition monitoring of machine tools and machining processes using internal sensor signals

    Författare :Jari Repo; Mihai Nicolescu; Dragos Axiente; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; condition monitoring; machine tool; machining process; milling; position encoders; signal analysis; Mechanical engineering; Maskinteknik; Materials science; Manufacturing and materials engineering;

    Sammanfattning : Condition monitoring of critical machine tool components and machining processes is a key factor to increase the availability of the machine tool and achieving a more robust machining process. Failures in the machining process and machine tool components may also have negative effects on the final produced part. LÄS MER

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Information modelling; manufacturing resource model; manufacturing system life cycle; STEP; PLCS; Informatics; Informatik;

    Sammanfattning : This thesis deals with information modelling within the scope of the manufacturing system life cycle, i.e. the development phase and the operation phase. LÄS MER

  5. 19. Model driven process planning for machining : Theory, application and improved information standards for efficient product realization

    Författare :Mikael Hedlind; Torsten Kjellberg; Fumihiko Kimura; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process planning; modeling; ISO 10303; CADCAM; kinematics; Beredning; modellering; ISO 10303; CADCAM; kinematik; SRA - Production; SRA - Produktion;

    Sammanfattning : Model driven process planning is a methodology that emphasizes the application of models to create, represent and use information of products, processes and resources. Industry today stores information in a fragmented manner, mainly document centered with the consequence of data duplication requiring comprehensive data management and maintenance. LÄS MER

  7. 20. Closed Force Loop Evaluation of Machining Systems

    Författare :Theodoros Laspas; Andreas Archenti; René Mayer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; machine tool loaded test; stiffness measurement; static accuracy; machine tool stiffness; Production Engineering; Industriell produktion;

    Sammanfattning : Machine tools accuracy has been a cornerstone in defining machining system capability and directly affecting dimensional and geometrical tolerance of machined parts. The effort for achieving higher precision and accuracy can be distinguished in two general ideas. LÄS MER
