Purpose of detail design of the drone is to do the deep engineering necessary for manufacturing and purchasing. Every component, from big motor to small screw shall be fully defined with data sheets, specifications, materials and dimensions with tolerances. All CAD models and other detailed information (calculations, tables, text descriptions, developer comments) shall be properly stored or documented with the possibility to track changes and to do the updates at later stages.
For the components which are decided for own manufacturing, the CAD detailed design data is the basis for prototype manufacturing process development: procurement of the raw material, jigs design, tools selection, CNC programming.
Capabilities and limitations of selected manufacturing processes and tools influence the design of drone details.
