A simple machining jig has been designed to rapidly and consistently cut chevron-notches in fracture specimens. The geometry of the jig automatically aligns and positions the specimens while a mechanical clamping arrangement secures pairs of specimens. The design of the jig is adjustable to accommodate any number of specimens within the range of cutting machines which use a rotating blade and a reciprocating cutting action.
