In milling, this may be the only such vibration that significantly affects the process. But drilling is more complex. While the tool is chattering in and out at some high frequency, it may also be swaying back and forth at a much lower frequency—essentially tracing a cone-shaped volume as the swaying tool rotates.

The geometric parameters of micro-end mill include shank diameter (d s), tool diameter (d t), equivalent tool diameter (d t ') that is 68% of (d t) [], taper angle (γ), total length (L), and tool length (L t), as shown in Fig. 2.In the micro milling process, the tool diameter of micro-end mill is usually less than 100 μm, which is ...
Abstract. Chatter is a self-excited vibration of parts in machining systems. It is widely present across a range of cutting processes, and has an impact upon both efficiency and quality in production processing. A great deal of research has been dedicated to the development of technologies that are able to predict and detect chatter.
Tool vibration generated under unsuitable cutting conditions is an extremely serious problem during face milling as it causes excessive tool wear, noise, tool breakage, and deterioration of the surface quality. In the current study, an artificial neural network (ANN) was used to predict tool vibration stability during face milling for different materials: Al 7075 and St …
Ion Beam Etching (or milling) is achieved by directing a beam of charged particles (ions) at a substrate with a suitably patterned mask in a high vacuum chamber. Oxford Instruments is a leading provider of IBE technology systems.

Large thin-walled parts are widely utilized in many different fields such as aircraft manufacturing. However, the vibration caused by the milling force during processing unfortunately affects the processing quality. To reduce the vibration, a multi-point flexible following support head is proposed, which can adjust the supporting force in mirror milling in real time. By installing …
Some of the ground surfaces on this workpiece show waviness resulting from process vibration. The wavelength of this waviness—the distance from peak to peak—might offer a clue to the cause of the vibration, and can be used to calculate parameters that might result in a smooth surface despite the vibration.
