IKONICS Advanced Material Solutions (AMS; Duluth, MN, US) has developed PAM (precision abrasive machining) technology for perforating composites and other brittle materials while minimizing substrate compromise. IKONICS says PAM is particularly beneficial for machining a variety of features and shapes, not limited to through-holes in the carbon fiber composites, fiberglass, Kevlar composites, ceramics, sapphire wafers and silicon wafers.
