Low-frequency resonance is a bigger problem than high-frequency resonance in general industrial machines. This little-recognized distinction is crucial in determining the best way to correct it.

Vibration is a fact of life in almost every machining operation. Whether you’re milling, drilling, turning, or grinding, vibration can result in chatter that can ruin a part. Fighting chatter has ...

Columbia physicist Isidor Isaac Rabi discovered nuclear magnetic resonance in the 1930s. Today, it lets doctors look inside patients.
