Machining of hollow core honeycomb sandwich materials is a challenging job as the mechanical properties of various layers (skin, core) are quite dissimilar, and the conventional solid cutting tool experiences a sudden change of conditions while machining that might lead to damage on the tool/part. Although, abrasive waterjets (AWJs) is highly efficient in the machining of advanced composite materials due to their unique characteristics, efficient machining of sandwich structures by AWJs needs many challenges to be addressed. This work presents various issues observed in AWJ machining of carbon- and glass- fiber skin based, aluminum sandwich structure composite materials, and the limitations of AWJs in processing these exotic materials. Finally, possible strategies for efficient machining of honeycomb structures were proposed for future investigation.
