High-speed camera measurements in the mechanical analysis of machining

In this paper, we present the application of high-speed camera recordings in the mechanical analysis of machining processes. The modelling of the workpiece-machine-tool mechanical system is a very complex and challenging engineering problem having important features at multiple scales both in time and in space. The observation and experimental analysis of such phenomena are important in terms of developing and validating the corresponding mechanical models and results. This paper is dedicated to summarize our experiences regarding the optimal measurement set-up and instrumentation of mechanical investigations using a commercial Photron FASTCAM SA5 High-Speed Camera System. Furthermore, the applicability of high-speed camera recordings are also provided via the detailed case study of shear angle estimation and chatter detection. (C) 2018 The Authors.
