Advances in composite machining with abrasive

Abrasive-waterjets are being used in many composite trimming applications. The macro morphology and geometrical features, such as kerf taper or waviness of cuts produced in composites are not different than those observed in other materials. However, depending on the composite structure, micro effects may be significantly different. This paper, an extension of a previously published work
