Definition

In general, vibration is a phenomenon where motion or oscillation occurs around an equilibrium point. This motion may be periodic or random. In Machine tools, the vibrations are induced from various sources such as the process, the environment, or the machine itself. They are usually undesirable. However, there are also self-excited vibrations which are commonly experienced in a wide variety of machining processes. See “Chatter” and “Stability” for details on those self-excited vibrations generated in machine tools.

Theory and Application

Machine tools basically move precisely according to operators’ commands or NC programs, and its motion is transferred to the machined shapes. However, there is more or less undesirable vibration generated in the machine tools, which deteriorates surface quality of machine parts and sometimes shortens tool life.

Theory

In general, vibration X(ω) is caused by exciting force F(...
