Abstract
An understanding of the mechanisms of striation formation on the surfaces produced by abrasive waterjet (AWJ) cutting is a crucial step in reducing or eliminating the striations. Various reported investigations and findings in this regard are reviewed and discussed. The sources of striation formation are classified into three groups; namely the nature of the step formation inherent to a jet cutting process, the dynamic characteristics of the waterjet, and the vibration of the machining system. It is believed that all these sources contribute to the formation of striations although it is difficult to separate their effects in practice. Recommendations are finally made on the future work and the approaches to reducing or eliminating striations on the AWJ cut surfaces.
