Chatter Suppression of External Grooving Tools

Procedia CIRP, 2017
Abstract Generating deep grooves using long blades is a challenge due to excessive chatter vibrations. In the present paper, an analytical simplified solution of the critical grooving width is obtained. It is found that a cross FRF of the tool dominates the solution.

Study on Suppression of Self-excited Chatter Vibration

Journal of the Japan Society of Precision Engineering, 1975
The self-excited chatter vibration in cylindrical grinding belongs to the wheel regenerative chatter. But in early grinding time, it can be modeled on the parametric vibration system based on the variation of the wheel periphery. The principle of the chatter suppression is that on the stability chart for the equation of motion the unstable grinding ...
