A method of manufacturing a laid-up, bonded and, cured composite part, includes filling a groove (64) on a facing surface of a tool (32) with a foaming, self-skinning sacrificial material and covering the facing surface of the tool with a caul sheet. The tool is heated to cure the foaming material, filling the grooveand forming a hard, smooth surface skin on the foam, flush with the facing surface of the tool. A series of plies (85) are laid-up on the facing surface of the tool to form a tool-side skin, and other components (84) of the part are laid-up on top of the tool-side skin plies. An adhesive/resin matrix is coated on or pre-impregnated into the skin plies and the components for bonding/curing to create a rigid integral assembly of the akin and components. A vacuum bag (71) is applied over the laid-up skin and components. The adhesive/resin matrix is bonded/cured to transform the skin and components into the rigid integral assembly. The tool is fixed in a known position on a CNC machine tool bed to position the facing surface of the tool at a known position for edge routing of the rigid integral assembly by a machine tool. A cutter (68) of the machine tool is guided on a predetermined path around the facing surface of the tool, with the cutter extending into the groove below the facing surface of the tool and cutting a peripheral edge around the rigid integral assembly. After edge routing, the rigid integral assembly is a finished part and is removed from the facing surface of the tool. |
