Precision machine tools such as lathes, grinding, lapping and milling machines are used widely in metal cutting production processes. Some require very high precision therefore monitoring of vibration is essential. Excessive vibration can impact product quality of the finished goods. It is also a typical indication of excessive tool wear and improper feed or speed settings. Additionally, collision can cause damage to the tool bit, the part or even worse the metal cutting machine itself. Collision needs to be minimized and avoided at all times.
