    Abstract

    Attempts to install a rotating tool at the end of a robot arm
    poly-articulated date back twenty years, but these robots were not designed for
    that. Indeed, two essential features are necessary for machining: high rigidity
    and precision in a given workspace. The experimental results presented are the
    dynamic identification of a poly-articulated robot equipped with an integrated
    spindle. This study aims to highlight the influence of the geometric
    configuration of the robot arm on the overall stiffness of the system.

    Abstract

    This paper proposes a method to vibration analysis in order to on-line
    monitoring of milling process quality. Adapting envelope analysis to
    characterize the milling tool materials is an important contribution to the
    qualitative and quantitative characterization of milling capacity and a step by
    modeling the three-dimensional cutting process. An experimental protocol was
    designed and developed for the acquisition, processing and analyzing
    three-dimensional signal.
