Passive / dynamic vibration control technology
boost metalcutting productivity
Uncontrolled vibration creates multiple problems in metalcutting operations. Varying forces
in the cutting process cause vibration and tool chatter that degrade part surface quality, quickly
wear or break cutting tools and damage machine tool components. Trends in product design can
also incite vibration. To enhance product strength and reduce assembly costs, manufacturers
increasingly machine parts from monolithic workpieces. Producing internal features of the parts
requires tools to reach into deep cavities, and the extended tool length exaggerates vibration.
Attempting to minimize vibration by reducing cutting parameters decreases productivity and
increases manufacturing cost.
Prime among the various approaches to vibration control are passive/dynamic systems
that utilize tuned-mass damper concepts to absorb vibration before it progresses and disrupts
the machining process.
