The steps of measuring the vibration of a numerical control drilling machine are as follows: 1. Measurement of the vibration quantity: measuring the size of the displacement, velocity and acceleration of the vibrating body at the selected point; the time history, frequency, phase and spectrum of the vibrator; the excitation is zero. 2.

Vibration in grinding machine is hard to measure. It is witnessed from the formation of waviness on the work piece and grinding wheel. The major causes of vibration in grinding machine are misalignment and unbalancing. These unwanted vibrations will reduce the life of both machine and tool, resulting in loss of production.

that a machine could be both a source and recipient of unwanted vibration. For example, a surface grinder is generally a vibration-sensitive piece of equipment that needs to be protected from floor vibrations. However, as the surface grinder reverses its heavy table during operation, it produces a large dynamic force, which may disturb other nearby
