Sep 18, 2019 In the micro-milling process, the minimization of tool chatter is critical for good surface finish quality. The analysis of chatter requires an understanding of the milling tool as well as the dynamics of milling system structure. Frequency response function FRF at the micro-milling tool point reflects dynamic behavior of the whole micro-milling machinespindletool system.

Apr 01, 2019 4. Avoid Chatter and Other Vibration. Chatter is tough on any tool, but it can be instant death to micro-cutters. Worse, you wont be able to hear it in micro-applicationsits just not loud enough. Chatter is a function of rigidity, which resists deflection and a tendency to vibrate and excite chatter, and resonance.
