Adaptive vibration reshaping based milling chatter suppression
International Journal of Machine Tools and Manufacture, 2019Abstract As a major obstacle to high performance milling, chatter will inevitably decrease tool life, material removal efficiency and workpiece surface quality. Active control based on actuators for chatter suppression has been developed for a long time.

Chatter stability of synchronized elliptical vibration assisted milling
CIRP Journal of Manufacturing Science and Technology, 2020Abstract This paper presents the dynamics to analyze the stability of ultrasonic elliptical vibration-assisted milling operations. The elliptical vibrations are delivered to the tool-tip with a piezo actuator integrated to tool holder at about 16.5 kHz with amplitudes of 10 μm and 5 μm in radial and tangential directions, respectively, with 90° phase

Journal of Engineering for Industry, 1988
Chatter vibration of long drills has been investigated using several drills with different overhang lengths and special drills with different pieces of additional mass. The frequency, amplitude, initiation boundary, and unstable range of chatter vibration were measured at various cutting parameters. The experimental results showed that the vibration is

Chatter Vibration of Lathe Tools. Part 1: General Characteristics of Chatter Vibration
Journal of Engineering for Industry, 1983The primary chatter vibration of turning tools is investigated experimentally. The vertical displacement of the turning tool and the fluctuating cutting force in the primary chatter vibration are measured simultaneously to investigate the characteristics and the resulting vibration mechanism, when cutting a top of the square thread of mild steel or ...

Chatter vibrations of high-performance motorcycles
Vehicle System Dynamics, 2013Motorcycle racing teams occasionally experience speed-limiting vibrations of around 25 Hz frequency in mid-corner. The nature of the vibrations has not been closely defined yet and the mechanics are currently not properly understood. Conventional motorcycle-dynamics models are shown here to reveal the existence of a vibration mode that aligns with the ...
