Webb9 sep. 2005 · At the tool tip, this vibration leaves waves in the machined surface. The waviness can cause the next cutting edge to experience a variable load. When that happens, this variable load feeds the vibration that already exists, making it worse. "Self-excited vibration" is one term for this phenomenon. "Regeneration of waviness" is another. http://article.sapub.org/10.5923.j.mechanics.20160603.03.html

Webb8 dec. 2024 · In this paper, a new stiffness orientation method is proposed to optimize milling path and improve stability of the robotic milling system. First, the principal stiffness directions of the robot are determined through experimental or calculated modal analysis. WebbAmong the different types of vibrations, chatter vibrations are defined as self-excited vibrations. When the tool/workpiece contact is not stiff enough, an oscillation is generated between them causing a distortion in the chip thickness parameter between two successive periods, t and t-T, where t is be the actual time and T the workpiece rotation …
