Technical Addendum, Layered sheet Based manufacture v2 Tooling
Year: 2026
Type: preprint
Abstract: This technical addendum proposes a tooling development and qualification framework for Functionally Graded Multi-Material Layering using Layered Sheet-Based Manufacturing. It addresses inspection, internal-cavity cleaning and controlled finishing from individual sheet preparation through staged assembly, consolidation and final release. The proposed protocol links component-specific access planning, material compatibility, tool and media recovery, and contamination control to documented hold points. Cleanliness, geometry, bond integrity, circuit function and sealing are treated as separate acceptance outcomes. A complementary tooling programme considers flexible or articulated “worm-like” probes, head-mounted pneumatic drives, external motors with flexible shafts, brushless electric tools, abrasive-flow machining, ultrasonic polishing and magnetic abrasive finishing. Development progresses from access and retrieval trials to non-cutting cleaning, controlled material removal and integrated demonstrator qualification. Combined methods require evaluation as a complete sequence, including cumulative removal and the effects of later operations on earlier acceptance evidence. The addendum establishes a proposed framework rather than a validated production process; operating limits, inspection capability and acceptance criteria require qualification for the actual component geometry and material stack.
