  4. 4. Evaluation of a Contactless Excitation and Response System (CERS) for process planning applications : An experimental study

    Master-uppsats, KTH/Industriell produktion

    Författare :Laura Montalban; [2016]
    Nyckelord :mechanical vibrations; natural frequencies; damping ratio; chatter; structural dynamic tests; stability lobe diagrams.; mekaniska vibrationer; egenfrekvens; dämpning; chatter; strukturdynamiska tester; stabilitetsdiagram.;

    Sammanfattning : Chatter vibration is a common problem for the manufacturing industry that limits the productivity, accuracy and surface quality of machined parts. This study is focused on the out of process methods, such as Stability Lobe Diagrams (SLD), that ensure the selection of the optimal cutting parameters in which the machining process is stable.
