contour milling, shallow slotting, contour milling and pocketing applications. Flutes Spiral-shaped cutting edges are cut into the side of the end mill to provide a path for chips to escape when an end mill is down in a slot or a pocket. The most common options are 2, 3, or 4 flutes. The more flutes, the more cutting edges but the

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.

Vibration analysis is a process that monitors vibration levels and investigates the patterns in vibration signals. It is commonly conducted both on the time waveforms of the vibration signal directly, as well as on the frequency spectrum, which is obtained by applying Fourier Transform on the time waveform.

Vibration problems generally result in noise, bad surface quality and sometimes tool breakage. The main sources are of two types: forced vibrations and self-generated vibrations. Forced vibrations are mainly generated by interrupted cutting (inherent to milling), runout, or vibrations from outside the machine.

Machining vibration is a common problem in CNC manufacturing. Milling, turning or drilling will all cause parts to suffer this torture. It affects the quality and efficiency of processing, will cause the finish of the parts to decrease, and will damage and significantly shorten the life of the end mill.

Vibration in cavity milling creates uneven wear on cutting tools and shortens tool life. While indexable insert milling cutters and solid carbide endmills differ in construction, they are both vulnerable to chatter and share some common vibration remedies. Indexable insert milling cutters are generally available in diameters down to one-half inch.
