What’s shakin’? Seco Tools on vibration control

Seco Tools looks at passive and dynamic vibration control in a recent technical article on the company's web site. In metalcutting, vibration is generated by the changing forces that occur when making chips. The intermittent forces are apparent in the interrupted cutting process of milling and also appear in turning operations when the toolholder bar is periodically loaded and unloaded as chips form and break. A passive/dynamic approach to vibration control for tools involves application of a tuned mass damper concept.
