Grinding Chatter and Vibrations
1986Grinding is a widely used machining process in applications requiring high production rates and very good dimensional accuracy and surface finish. It is also one of the more complex metal working processes and one of the less understood1. Consequently, successful use of grinding in practice is highly dependent on the level of expertise of the machinist

The effects of torsional vibration on chatter in grinding
Journal of Materials Processing Technology, 1999Abstract The modelling of chatter in grinding has been the subject of much research. The majority of the theoretical analyses have ignored the effects of torsional vibration in both the spindle system and the workpiece drive. A recent paper has indicated that these torsional effects could be significant and a frequency domain analysis has been ...

Active vibration control for chatter suppression
38th Structures, Structural Dynamics, and Materials Conference, 1997The vibration absorber, in its various forms, is a well-known control strategy that reduces the forced vibratory response of structures by introducing a carefully tuned, auxiliary degree of freedom. The method is simple, effective, and widely used.

CONTINUITY AND BREAK OF CHATTER VIBRATION STATUS
Chinese Journal of Mechanical Engineering (English Edition), 2008By turning a specifically designed conical part, complete process of metal cutting, in which the chatter occurs and expands,is recorded and analyzed. This process exposes that chatter vibration has two characters called continuity and break.The continuity character means that vibration extent enlarges continuously while chatter frequency is almost ...

Magnetostrictive Actuator for Chatter Vibration Suppression of Boring Bar
2018 IEEE/ASME International Conference on Advanced Intelligent Mechatronics (AIM), 2018Boring is a machining process to manufacture the hole. During the deep hole process, boring bar with a high aspect ratio is easy to chatter under various cutting conditions, and it causes poor surface roughness and dimensional error. This paper aims to develop a new magnetostrictive actuator to suppress the chatter vibration of a high aspect ratio ...

On the self-excited chatter vibration in motorcycles
2023This study is focused on the understanding of the nonlinear effects of tyre forces and chain geometry on motorcycle chatter, a self-excited oscillation arising at the rear wheel during heavy braking manoeuvres. In particular the post-bifurcation criticality is assessed, whether subcritical or supercritical, with respect to travelling speed.

Prediction and control of vibrations and chatter in machining
2015Nowadays, high levels of automation, integration and flexibility are required to increase the competitiveness of manufacturing industries. In this perspective, an increasing interest in unmanned, intelligent machining systems has emerged. Ideally, future production systems will be designed to automatically perform complex tasks, such as planning and ...
