Abstract
This paper addresses the use of structural dynamics concepts applied to virtual manufacturing. A review of vibration fundamentals is done using a single degree of freedom system. Then, a lab procedure to experimentally determine the frequency response functions and vibration modes of a steel beam by modal fitting is explained. An introduction to receptance coupling substructure analysis is then provided, using an example with two single-degree-of-freedom systems, which are assembled through a flexible coupling. Finally, milling dynamics concepts are introduced, and the stability lobe diagram for an up milling condition is developed. This work provides an explanation of how to use structural dynamics to select cutting parameters that will provide an optimized performance of a milling machine, allowing to maximize profit of the productive process.
