What does the term 'set-up tools' refer to in aerospace assembly?

The term 'set-up tools' in aerospace assembly refers to tools that determine the layout of assembly. These tools are critical in ensuring that all components are placed in the correct position and orientation before the actual assembly process begins. Proper layout is essential for maintaining accuracy and consistency in the assembly of aerospace structures, which can be complex and require precise tolerances to function safely and effectively.

Set-up tools might include alignment jigs, templates, and fixtures that help position parts relative to each other according to engineering specifications. By establishing the correct layout, these tools help assembly mechanics achieve the intended design, minimize errors, and enhance overall efficiency during the manufacturing process. Proper use of set-up tools is a key competency for mechanics in aerospace assembly, as it directly impacts the final quality of the assembled product.
