What is aerospace CNC machining?

Aerospace CNC machining is a manufacturing process used to produce precision components for aerospace applications. It involves the use of computer numerical control (CNC) machines to shape, cut, and drill aerospace-grade materials such as aluminum, titanium, stainless steel, and composites.

 

Why is CNC machining important in aerospace?

CNC machining provides exceptional precision and accuracy, making it crucial for aerospace applications where strict tolerances and high-quality standards are required. It allows for the production of complex and lightweight components with tight dimensional control, ensuring optimal performance and safety. Precision is crucial in aerospace CNC machining because aerospace components must comply with stringent safety and performance standards. Even slight deviations from the design specifications can lead to component failure, which can be catastrophic in flight applications.

Aerospace CNC Machining Processes

Aerospace CNC (Computer Numerical Control) machining processes involve the use of specialized machinery and cutting tools to shape and create parts required for aerospace applications. Given the high-performance standards and precision these parts often demand, specialized processes and techniques are used in the aerospace industry. Here are some of the key CNC machining processes used:

1. Milling

This process involves removing material from a workpiece by advancing (or feeding) it into a rotating cutter with multiple sharp edges, called a mill. Aerospace components often require complex surfaces, like those found on airfoils or engine casings, and CNC milling machines can shape these with high precision.

2. Turning

Turning is performed on a lathe and involves cutting a part as it rotates. CNC lathes can manufacture precise cylindrical components such as bushings, shafts, or couplings commonly used in the aerospace industry.

3. Drilling

Creating precise holes in components for aerospace applications is crucial. CNC drills are used to create accurate and repeatable holes in components, which could be used for everything from fuel system parts to airframe construction.

4. Grinding

This machining process provides very fine finishes and extremely accurate dimensions, which are often required for the components of aircraft engines and landing gear. Grinding uses an abrasive wheel to remove material from the surface of a workpiece.

5. Electrical Discharge Machining 

EDM is particularly used for hard metals or complicated designs that are difficult to machine with traditional methods. It involves using electrical sparks to shape a part and is very precise, making it ideal for intricate or delicate aerospace components.

6. 5-Axis and Multi-Axis Machining

Rather than the traditional 3 axes (X, Y, and Z), 5-axis CNC machines can move a part or a tool on five different axes simultaneously. This capability is particularly useful for complex aerospace components with intricate geometries, as it can significantly reduce the setup time and improve the accuracy of the machined part.

7. High-Speed Machining

High-speed machining involves using high cutting speeds and quick feed rates to shape aerospace materials quickly and efficiently. This process is crucial for shortening production times and ensuring that components can be produced with the required surface finish and dimensional tolerances.

8. Boring

This process is used to enlarge holes or cylindrical cavities made by an earlier process or to cut a tapered hole. Boring in aerospace manufacturing has to be very precise to ensure the reliability of the components.

9. Broaching

Broaching is used to remove material with a series of cutting teeth. It is common for creating keyways or other detailed profiles in aerospace components.

10. Thread Milling

Creating threads in components for aerospace applications is critical. CNC machines can create very accurate internal and external threads on parts such as bolts, casings, and engine components.

Considerations for Aerospace CNC Machining

  • Material Selection: Aerospace components may require lightweight yet strong materials like titanium, aluminum alloys, invar, tungsten, or specialty plastics.

  • Tolerances: Aerospace components often require extremely tight tolerances to ensure safety and performance.

  • Surface Finish: Surface finish can be important for aerodynamic properties as well as ensuring the proper fit of parts.

  • Quality and Certification: All aerospace manufacturing processes are subject to rigorous quality standards, such as AS9100, and require precise documentation and traceability.

Aerospace CNC machining must not only consider the physical production of parts but also factors related to design (such as CAD and CAM integration), prototyping, testing, and adherence to regulatory and quality standards.
