    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

  4. 3. An Analysis of Machining System Capability and Its Link with Machined Component Quality

    Författare :Tomas Österlind; Cornel-Mihai Nicolescu; Tatar Kourosh; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machining System Capability; Elastic Linked System; Spiral Bevel Gear Face Milling; SRA - Production; SRA - Produktion;

    Sammanfattning : Machining components out of tolerances is of no use in competitiveproduction. The machining system sets the limitations of dimensionalaccuracy and surface quality of a machined component. The capabilityof the machining system describes these limits in terms of specifiedvalues.

  5. 4. Concepts for mechanized tree planting in southern Sweden

    Författare :Back Tomas Ersson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The underlying reason for mechanizing tree planting in southern Sweden is the biologically good planting results produced by today's tree planting machines. Nevertheless, the productivity of these tracked excavators with crane-mounted tree planting devices is too low for them to compete economically with manual planting. LÄS MER
