The manufacturing sector has seen notable expansion as a result of the increased demand for elevated quality of goods and computer numerical control (CNC) equipment, allowing developers to generate such elevated quality and high-complexity items at greater speeds. Milling is a useful methodology that is frequently used in manufacturing and involves the manufacturing including both basic and complicated configurations. The depth of cut necessary for the machining processes, as well as the level of surface quality, can be determined by modelling the mechanical and topological layout of a mill...

The present investigation is an attempt to contribute towards the improved understanding of the dynamic stability of rotating shaft under parametric excitation. The dynamic stability of rotating shaft subjected to longitudinal parametric excitation has been investigated theoretically and experiments have been carried out to validate some of the theoretical findings. The equations of motion have been derived using finite element method. For the rotating shafts the instability regions have been established using Floquet's theory.The dynamic stability of a rotating shaft having fixed-free,...
