Summary on Grant Application Form |
|
Machining accounts for approximately half of all manufacturing techniques, and its productivity is, ultimately, limited by the onset of instability known as chatter. Regenerative chatter is the primary form of unstable self-excited vibration that can occur in milling, turning, and boring, and despite the recent research into the mechanisms of chatter, the results are rarely applied in practice. Chatter is particularly problematic in the case of the aerospace and advanced manufacturing sectors where exacting design requirements lead to ultra-high precision or high speed milling of components with a complex geometry that are lightweight, flexible, and lack structural damping.This proposal outlines a five year program of work that will develop a new perspective on chatter avoidance in milling to enable enhanced productivity. By harnessing non-linear dynamics, structural modifications, and active control, two changes will be brought about. First practical techniques will be available for process design and optimisation. Second, adaptive and self-sensing machines will be realised that are capable of enhanced productivity through automatic chatter mitigation.
