ABSTRACT: To address the Air Force need for an advanced power skiver tool capable of reliably skiving gap-fill material to precise heights with repeatable accuracy, Physical Optics Corporation (POC) proposes to advance the development of the innovative Pneumatic Height-Adjustable Skiving Tool (PHAST). By integrating a unique blade system, innovative feed rate control, and a novel gear topology, the PHAST reliably trims loaded gap fill material to a user-defined height over varying surface contours, ensuring a smooth, consistent finish in a single pass. In Phase I, POC demonstrated the feasibility of the PHAST to manufacturing readiness level (MRL)-4 by building a completely functional prototype tool capable of skiving gap-fill materials to precise heights in a single pass on representative samples with complex contours. In Phase II, POC will continue development of the PHAST to improve skiving precision, durability, safety, and manufacturability, as well as begin tailoring the tool to immediate customer needs, culminating in an MRL-7 prototype, capable of reliably skiving in a production-representative environment, developed with specific application relevancy and a clear, detailed path toward transition to production. BENEFIT: Meeting the technical and operational requirements set forth by the U.S. Air Force for an advanced power skiving tool will allow POC to develop the PHAST for all types of assembly operations in both the military and commercial sides of the aerospace industry, where outer mold line control is critical, including assembly and rework of stealth aircraft and unmanned aerial vehicles (UAVs). In addition to gap-fill trimming, the PHAST may be utilized in fastener flushness applications in which fastener holes must be filled and consequently trimmed to meet low observability requirements. The PHAST can also be used to trim shim buttons and cured liquid shim down to the required heights in a single pass for proper skin alignment to reduce the cycle time and cost associated with meeting step and gap requirements. All of these capabilities apply not only to the military and defense side of manufacturing but to other commercial transportation areas as well, such as automotive and boating, where the use of composites and fill materials is increasing and trimming materials to exact specifications is necessary to meet aerodynamic and fluid dynamic requirements.
