Vibration is a mechanical phenomenon whereby oscillations occur about an equilibrium point. The word comes from Latin vibrationem ("shaking, brandishing"). The oscillations may be periodic, such as the motion of a pendulum—or random, such as the movement of a tire on a gravel road.
N-2-1 fixturing schemes (N > 3) are often used for large or compliant workpieces in machining. However, the impact of N - 2 - 1 fixturing on product geometric variation is not well understood because of the uncertainty of contact under the overconstraint condition.
Controlling Machine Vibration And Shock Dynamic loads, and the resulting vibration or shock, are a fact of life with rotating and oscillating machinery. Both shock and vibration can damage equipment, increase operating costs, reduce quality and productivity, and generate objectionable noise levels.
