Investigating dynamics of machine tool spindles under operational conditions [PDF]
Chatter is one of the major problems in machining and can be avoided by stability diagrams which are generated using frequency response functions (FRF) at the tool tip.

This paper gives an analytical approach for investigating free and forced transverse vibrations of a clamped‐free rotating annular disk and obtaining the acoustic pressure distribution around the spinning disk. In the beginning, a modal analysis based on new analytical methods is carried out to find natural frequencies and mode shapes of the disk ...
