Tooling engineering refers to the process of designing and developing specialized tools that are used to manufacture parts and components. These tools can include molds, dies, fixtures, jigs, gauges, and cutting tools, all crucial in shaping raw materials into the precise parts required for aerospace applications. Given the aerospace sector’s emphasis on safety and performance, tooling engineers focus on achieving exact tolerances and ensuring repeatability across production batches.
In aerospace projects, tooling engineering ensures that every element of the manufacturing process operates efficiently and produces components that meet the rigorous standards set by regulatory bodies.
The Role of Build to Print Manufacturing
Build to print manufacturing is a model where a manufacturer produces parts strictly following the detailed designs and specifications supplied by the client. Unlike design and build contracts, in build to print, the client’s engineering team controls the design, specifications, and quality requirements, while the manufacturer focuses on executing these precisely.
Within this framework, tooling engineering becomes critical as the manufacturer develops the tools necessary to meet detailed specifications. Using the exact blueprints, tooling engineers create the means to replicate complex aerospace components with high precision.
This manufacturing approach is beneficial in aerospace because it allows companies to leverage suppliers’ specialized manufacturing expertise without relinquishing control of the design, thus maintaining strict quality and safety compliance.
Tooling Challenges in Aerospace Build-to-Print Projects
Tooling engineering in built to print is not without challenges. Some of the significant hurdles include:
-
Precision Requirements: Aerospace parts often require tolerances within microns, meaning the tooling must be impeccably designed and maintained.
-
Material Considerations: Many aerospace parts use advanced materials, including titanium, aluminum alloys, and composites, which can be difficult to machine or mold.
-
Complex Geometries: Aerospace components can include intricate shapes with tight curves and thin walls, requiring innovative tooling solutions.
-
Volume Variations: Aerospace projects might vary in production volume from low runs of prototypes to full-scale production, necessitating adaptable tooling solutions.
-
Regulatory Compliance: Tooling and manufacturing processes must comply with stringent aerospace industry standards and certifications, such as AS9100.
Composite Manufacturing’s Growing Influence
Composite manufacturing has become a game-changer in aerospace due to the materials’ high strength-to-weight ratio, corrosion resistance, and tailorability. However, composite materials necessitate specialized tooling engineering because their manufacturing processes differ significantly from traditional metals.
Tooling for composite manufacturing must accommodate processes such as automated fiber placement, resin transfer molding, and autoclave curing. These procedures require highly engineered molds and fixtures designed to maintain precision under variable temperature and pressure conditions.
Integrating composite manufacturing into build to print manufacturing expands the capabilities of aerospace manufacturers to create next-generation parts while relying on detailed client designs.
