A cure tool assembly and method of manufacturing a composite part. The cure tool assembly may include a rigid cure tool having a cutter groove and a securing groove formed therein. The cutter groove may be spaced apart from and formed around the cutter groove. The securing groove may be slanted inward, away from a peripheral edge of the rigid cure tool. The cure tool assembly may also include a first sacrificial material located in the cutter groove and a second sacrificial material located in the securing groove. Composite material placed onto the outer surface of the rigid cure tool may bond with the second sacrificial material during cure, creating a desired hold-down force to keep the composite material in place. The resulting cured part may be cut along the cutter groove, thus cutting through the composite material and into the first sacrificial material.
