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 minimise vibration by reducing cutting parameters decreases productivity and increases manufacturing cost. Prime among the various approaches to vibration control are passive/dynamic systems that utilise tuned-mass damper concepts to absorb vibration before it progresses and disrupts the machining process. Vibration – A common issue All sectors of industry recognise excessive vibration as a destructive condition. Repetitive operating and/or external forces generate sympathetic motion that can resonate within a machine, building, or bridge and grow to a dangerous magnitude. Manufacturers and builders often apply tuned mass damper concepts to overcome vibration. A tuned mass damper is a component that is suspended within…
