Abstract: This paper reviews on the various analyzing techniques of chatter stability in high speed milling. Milling at high spindle speed is an effective technology for processing various materials. During milling, unstable self-excited vibrations known as regenerative chatter can occur, causing excessive tool wear or failure and a poor surface finish on the machined work piece. There are several analyzing techniques that are used to increase the stability of the machining process such as, fuzzy arithmetic techniques, stability lobe diagram(SLD),Structural dynamic modification. Based on these analyzing techniques how the operating variables are changed to obtain the different predicted results is studied.
Keywords: chatter, spindle speed.

Introduction: High speed milling is extensively used in manufacturing process. The generation of complex shapes with high accuracy and quality is the main advantage of milling process. In a real world setting there are many variables that influence a machining process and each one can carry small errors or uncertainties, which can lead to major deviations in the finished quality of fabricated parts. It therefore becomes important to research novel models to account for parameter uncertainties in order to develop more practical models.
