Dynamic Modeling and Dynamic Analysis of the Boring Machining System
The boring operation is a metal cutting process widely used in industry. The inherent properties of the long, slender boring bar make it susceptible to self-excited chatter during machining. The main focus of this thesis is directed at developing a system model which correctly describes the boring …

A theoretical and experimental investigation of the BTA deep hole tool support in the machining zone
… alignment with the piloting hole depends on the boring bar to which the tool appears as a solid extension. This study shows that the alterations in the output quality and the support pads' wear pattern can be explained by in-process encountered boring bar bending. This is because even minor …

Overhung-boring bars: The performance of undamped and damped bars under static and dynamic conditions when machining metals
… behaviour of some new designs of slug damped boring bars with a 10 to 1 overhang ratio. The bars were mounted on a centre lathe. The static behaviour of a boring bar in relation to the geometric form errors that might be produced during boring was studied both analytically and experimentally. …

Vibration Control for Chatter Suppression with Application to Boring Bars
… hardware and control system design for a boring bar application. Initially, we treat the cutting forces merely as an unknown disturbance to the structure which is essentially a cantilevered beam. We then approximate the structure as a linear single-degree-of-freedom damped oscillator in …
