A REVIEW ON PREDICTION OF CHATTER STABILITY IN HIGH SPEED MILLING

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 selfexcited 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 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.
