Chatter Vibration in Drilling

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, 1983
The 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, 2013
Motorcycle 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 ...

Chatter Vibration of Lathe Tools

Journal of Fluids Engineering, 1956
Abstract This paper deals with a chatter vibration which occurs frequently when metals are being machined. It has been ascertained experimentally that the chatter is a self-excited vibration caused by the lag in fluctuation taking place in the horizontal cutting force behind the horizontal vibration of the work.

Simulation of Chatter Vibrations in Reaming

Volume 3: Design and Manufacturing, 2007
A time domain approach is used to study the cutting conditions in reaming process that leads the system to regenerative chatter vibrations. The dynamic analysis of the system includes inertia of the tool, centripetal and Coriolis terms, damping and the first mode bending of reamer. A model of cutting forces proportional to chip cross sectional area and

Active vibration control for chatter suppression

38th Structures, Structural Dynamics, and Materials Conference, 1997
The 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.

Suppression of Chatter Vibration in Drilling

Journal of Manufacturing Science and Engineering, 1998
In this study, from the viewpoint of suppressing chatter vibration in drilling, the effects of cutting conditions on the initiation boundary of chatter vibration were investigated experimentally. Furthermore, the application of an impact damper on drills was attempted to suppress chatter vibrations.

The Modulation of Chatter Vibrations

Journal of Engineering for Industry, 1969
The results of several experimental investigations concerning the nature of machining chatter are discussed. They indicate that chatter vibrations are generally amplitude modulated and that the chatter frequency may or may not vary from the free vibrational frequency of the chattering component.

Simulation of Chatter Vibrations for Wiper Systems

SAE Technical Paper Series, 2002
<div class="htmlview paragraph">An experimental investigation is first carried out to analyze the influence of the geometrical configuration of a wiper system on the chattering occurrence. The measurement results show a combined influence of the load applied on the rubber blade and the attack angle on the vibratory level of the blade.
