The effect of cutting jet variation on surface striation formation in abrasive water jet cutting
2003
Abstract Abrasive water jet machining is an emerging technology which can shape almost all engineering materials, but also produces a characteristic striated surface finish which limits its potential applications. In this study, the characterisation of different materials’ cut surfaces is investigated using a scanning electron microscope. The effect of abrasive particle distribution in the jet on striation formation is detailed. A non-invasive technique: laser Doppler anemometry is used to analyse the abrasive particle distribution in the jet. Furthermore, the mechanisms of striation formation are discussed in detail and an effective striation minimisation technique applied to the cutting process is outlined.
