Integrated solution Chatter is the product of every element in the cavity milling process, including the tools, the machine and the workpiece. The total system remedy is to eliminate all vibration sources that can lead to harmonic responses. The tighter and more robust the machine's ways and spindle, the less vibration. Keep the structure rigid from spindle to cutting edge. Clamp the part to minimize movement, vibration and deflection, and add support close to the areas to be machined.
Vibration is most likely in workpieces with a long overhang.
Unlike solid adapters that transmit vibrations readily, today's vibration-damping adapters have an internal chamber containing a heavy body suspended on rubber bushings. Vibration-damping adapters are also available with stable Capto couplings to minimize runout. Machine operators should position the milling cutter as close to the tuned adapter as possible. Tooling is just one element in the campaign against vibration. If none of these remedies work in your particular case, ask your tooling supplier for recommendations on your machine, your workpiece and your procedures.
