Effects of bearing clearance on the chatter stability of milling process [PDF]

, 2010
In the present study, the influences of the bearing clearance, which is a common fault for machines, to the chatter stability of milling process are examined by using numerical simulation method.

Chatter in manufacturing system: Prediction and detection [PDF]

Tehnika
Chatter is a phenomenon that periodically occurs in machining systems. Its occurrence in machining processes excites the tool and other elements of the machining system, creating "chatter marks" on the workpiece surface, which affects the quality of the ...

Chattering suppression of the sliding mode observer for marine electric propulsion motor based on piecewise power function

Frontiers in Energy Research, 2022
The sliding mode observer (SMO)–based sensorless control is essentially a discontinuous switching control algorithm. Therefore, there is large speed or torque chattering in the permanent magnet synchronous motor (PMSM) with existing sliding mode observer–

Suppression of period doubling chetter in high-speed milling by spindle speed variation [PDF]

, 2011
Spindle speed variation is a well known technique to suppress regenerative machine tool vibra- tions, but it is usually considered to be effective only for low spindle speeds.

The role of tool geometry in process damped milling [PDF]

, 2010
The complex interaction between machining structural systems and the cutting process results in machining instability, so called chatter. In some milling scenarios, process damping is a useful phenomenon that can be exploited to mitigate chatter and ...

Dynamic Modeling and Cutting Stability of Rotating Tapered Composite Cutter Bar considering Material Damping

Shock and Vibration, 2020
Traditional milling cutter bars are generally made up of metals and exhibit poor capacity of chatter suppression. This study proposes an anisotropic composites tapered cutter bar for increasing natural frequency and damping and finally achieves the goal ...

Chatter Suppression during Milling of Ti-6Al-4V Based on Variable Pitch Tool and Process Damping Effect

Machines, 2022
Regenerative chatter is a major limitation in the milling of Ti-6Al-4V, resulting in undesirable surface and reducing cutting efficiency. It is well-acknowledged that variable pitch cutter and the process damping effect are effective methods to suppress ...
