done on various mechanisms and characteristics of chatter. The cutting process with variable feed is one of the principles of arising of chatter vibrations. That results in the variable dynamic cutting force. The approach to this problem can be experimental and theoretical. The former is often used for supporting the latter, and for getting instructions for improvements of work.

Abstract. In grinding process, chatter vibrations known as self-excited vibrations, become increasingly problematic and must be avoided. Firstly, experimental measurements of chatter vibrations in a numerical control (NC) grinding machine tool are introduced for the case of a special alloy workpiece being carried on. Then, frequency spectra of chatter vibrations are analyzed. The

Machining vibrations Wikipedia

Machining vibrations, also called chatter, correspond to the relative movement between the workpiece and the cutting tool.The vibrations result in waves on the machined surface. This affects typical machining processes, such as turning, milling and drilling, and atypical machining processes, such as grinding.A chatter mark is an irregular surface flaw left by a wheel that is out of true in
