Manufacturing engineering

Self-excited vibration that limits a cut

In manufacturing engineering, chatter is a self-excited vibration between tool and workpiece in cutting operations such as milling or turning, in which each pass cuts into the wavy surface left by the previous one, feeding energy back into the vibration until it grows and ruins the finish and the tool. Altintas and Budak's 1995 Analytical prediction of stability lobes in milling gave the standard way to predict the spindle speeds and depths of cut at which this regenerative chatter sets in, mapped as stability lobes. The referent is a dynamic instability of the machining process, measured against a stability boundary, and it is a different construct from a glacial scar or a bouncing ski even though all share the word.[1]

Unit
The depth of cut and spindle speed at which cutting becomes unstable
Recovery means
Stable cutting is restored by choosing speed and depth inside the stability lobes, or by damping or altering the tool-workpiece dynamics
Measured by
Predicted by stability-lobe diagrams and detected by vibration sensors and the characteristic chatter surface finish

Ski engineering

A ski vibrating and skipping off its edge

In ski engineering, chatter is the high-frequency vibration of a ski or snowboard against the snow that makes the edge skip and lose grip, usually at speed, on hard or icy snow, or late in a carved turn, so the ride feels rough and control degrades. Rothemann and Schretter's 2010 Active vibration damping of the alpine ski treats these bending vibrations as the thing ski construction and damping systems are designed to suppress so the edge stays in contact with the snow. The referent is unwanted mechanical vibration of the ski that breaks edge contact, measured by the ski's vibration amplitude and damping, and it is distinct from a machine-tool instability or a glacial rock scar.[2]

Unit
Vibration amplitude and damping of a ski in contact with snow
Recovery means
Grip returns as vibration is damped by ski construction, tuning, or reduced speed so the edge regains continuous snow contact
Measured by
Quantified by the ski's vibration amplitude and frequency and by damping ratio during edge contact
