To manufacture a decorative hardwood panel with cut-out shapes and raised relief detailing, a combination of cutting and potentially some forming techniques would be most effective. Here's a detailed explanation:

1. Wastage - Cutting (CNC Routing): CNC routing is the primary technique for creating both the cut-out shapes and the raised relief detailing. A router can precisely cut complex profiles into hardwood. The advantage is high accuracy, the ability to create intricate designs, and consistent results. A disadvantage is the need for a suitable router bit and potential for tear-out on the edges of the wood.
2. Wastage - Drilling (Hand or Powered Drill): Drilling would be used to create pilot holes for any joinery methods required to attach the panel to the furniture piece. This could include dowels, screws, or other fasteners. The advantage is creating precise holes for assembly. A disadvantage is the potential for splitting the wood if the drill bit is too aggressive.

Justification Summary: CNC routing is the ideal choice for achieving both the intricate cut-out shapes and the raised relief detailing. The ability to program the router allows for complex and precise designs. Drilling provides the necessary holes for assembly. The use of hardwood necessitates careful consideration of router bit selection to minimize tear-out. The combination of these techniques provides a robust and aesthetically pleasing solution for the decorative panel.
