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 grinding or regular mark left when turning a long piece on a lathe, due to machining vibrations. As early as 1907, Frederick W. Taylor described machining vibrations as the

A chatter mark is an irregular surface flaw left by a wheel that is out of true in grinding or regular mark left when turning a long piece on a lathe, due to machining vibrations. As early as 1907, Frederick W. Taylor described machining vibrations as the most obscure and delicate of all the problems facing the machinist, an observation still true today, as shown in many publications on machining. Mathematical models make it possible to simulate machining vibration quite accurately, but in practice it is always difficult to avoid vibrations.

Effect of grinding forces on the vibration of grinding

The vibration behavior of the grinding machine spindle system is conditioned by both the vibration characteristics of the assembly components, i.e. shaft–bearing–housing system and the external grinding process forces. While vibration characteristics of the shaft–bearing–housing components were approached by many reliable mathematical
