Time Series Modelling of Surface Topography Generated by Ultrasonic Machining Process

摘要

In these studies the surface roughness profiles were modelled and analysed for a better understanding of the mechanism of metal erosion in USM. Different materials were selected for this purpose based on their diverse properties of brittleness, hardness and amorphism. Owing to the stochastic nature of the surface roughness, time series analysis was adopted for its modelling and analysis.
