What Is Aerospace CNC Machining
Aerospace CNC machining is a specialized and exacting manufacturing process that plays a crucial role in the creation of a wide array of components and assemblies within the aerospace industry. This includes intricate parts for engines, the structural elements of aircraft, and the sophisticated systems found in spacecraft. The essence of aerospace CNC machining is rooted in its advanced automation and meticulous precision, facilitated by computer numerical control (CNC) systems that guide the machine tools with exactitude to fabricate parts that adhere to the most detailed design specifications.
Lightweight Components
In the aerospace sector, the weight of a component is critical to design. CNC machining technology is able to create thin-walled, yet strong, lightweight material structures to meet the needs of the aviation and air defense industries. Through sophisticated path planning, CNC machining is able to create complex structures and surfaces, and even tiny nooks and crannies can be precisely machined. While this fine machining may take longer than a rough cut on a flat surface, it is essential to achieving design requirements.
Minimum Part Error
Aerospace components manufactured using traditional machining methods are more prone to defects. However, with precision CNC machining, the possibility of errors is reduced to an extremely low level. This is because the high-precision CNC machining process ensures that aerospace components can strictly adhere to design specifications, thereby ensuring the quality and reliability of the components.
High Precision
In the machining of aerospace components, high precision is crucial. These parts often have complex geometries that require precise machining from multiple angles. Tight tolerance requirements ensure parts fit precisely within aircraft assemblies. The application of CNC machining technology in the aerospace industry ensures the precise manufacturing of components and avoids failures during assembly and operation.
Consistency and Efficiency
The manufacturing of aerospace components is highly dependent on precision machining due to high precision and tight tolerances. This processing method not only reduces material waste, but also improves production efficiency. It helps achieve perfect part design, including precise inside corner radii and machineable hole sizes, significantly reducing machining time.
Reduced Machining Cost & Quick Production
Combining high precision with rapid production reduces the cost of each part, saving the cost of material waste, rework errors and labor. Increased productivity also helps increase profits.
Applications of Aerospace CNC Machining
There are numerous applications for CNC machining within the aerospace industry, the most common of which being:
Seats: In aircraft and spacecraft, the weight of seats is an important consideration. However, with CNC machining, aluminum and other lightweight metals can be used to create seats that are both strong and light.
Shafts: Shafts play a key role in transmitting power in the aerospace industry. CNC machining can produce strong shaft components using high-temperature resistant materials.
Oxygen Generation Components: CNC machining technology can produce oxygen generation system components that are both light and durable and can withstand high temperatures to ensure the effective operation of safety systems.
Valve Components: Valves are widely used in the aerospace industry. CNC machined valve components ensure the accuracy of the components, as well as the efficiency and safety of operation.
Electrical Connectors: Given space and weight constraints, manufacturers can use CNC machining technology to manufacture connectors that are essential in aircraft electrical systems.
Housings: Long and large components in missile housings require strong materials and precise machining. CNC machining provides the required accuracy and strength.
Filter Bodies: In Ardel's experience, we are able to accurately machine complex air and liquid filter housings. For one customer, we successfully manufactured a multi-feature filter body with complex geometry using a single-setup Swiss lathe, reducing machining time and maintaining an overall tolerance of 0.006 inches or better.
Finishing And Coating Aerospace CNC Machined Parts
Even though there are several surface finishing options for CNC parts, not all surface finishes are suitable for the purpose. Aerospace manufacturers utilize four major types of surface finishing and coating. These include:
Passivation
Passivation is a widely used surface treatment technique that improves the aesthetics, durability, and functionality of aerospace CNC machined parts. Most aerospace parts may contain impurities or micro-roughness after machining, which may affect the performance of the part. Passivation can avoid these problems, making aircraft parts chemically resistant and reducing maintenance requirements.
Anodizing
Anodizing is a surface treatment method that forms a uniform oxide layer on the surface of the part by immersing the part in an electrolyte. For example, anodizing of aluminum can provide a corrosion-resistant surface treatment. There are two types of anodizing used on aerospace parts: Type II and Type III.
Type II anodizing forms a thin, decorative protective layer on the surface of the part. This thin layer, while beautiful, can be susceptible to wear and corrosion. Type III anodizing, on the other hand, forms a hard, protective layer on the surface of the part.
Polishing
Polishing is an ideal and straightforward surface treatment technique for improving the surface quality of CNC aerospace parts. This surface treatment involves smoothing the rough surface of an aerospace part with an abrasive until it becomes smooth and attractive.
Polishing effectively improves the durability of aerospace machined parts by reducing the risk of cracking or flaking. However, polishing aerospace parts can take longer and can increase CNC machining costs.
Powder Coating
This is another widely used surface treatment method for metal aerospace parts. Its durability and versatility in functionality make it a popular choice for surface treatment of aerospace CNC machined parts. Powder coated CNC parts are able to resist scratches and will not fade quickly over time. In addition, this treatment option provides aerospace part manufacturers with a wide range of color options for improved aesthetics and flexibility.
Common Materials Used In Aerospace CNC Machining
When discussing aerospace manufacturing, people tend to immediately think of the engine or wings of an aircraft, but in reality, an aircraft is made up of millions of parts. For example, a Boeing 747 contains more than 6 million parts. Not all of these parts are made using CNC machining. Of those that are, a variety of materials are used.
Lightweight Metals
The CNC machining materials used by aerospace companies have two key properties: strength and weight. Although metals like steel are considered very strong, they are not suitable for most parts. This is because they are very heavy and make the aircraft less fuel efficient.
Therefore, the aerospace industry tends to use metals that are both strong and lightweight, such as titanium and aluminum alloys. These two metal materials are easy to process in CNC machining. For example, titanium is about 30% of the strength of steel and only 50% of the weight. It also has excellent resistance to high temperatures and corrosion, making it ideal for functional and external parts of aircraft.
Aluminum is lighter than titanium, but about half as strong. This easy-to-process metal is more cost-effective than titanium. It is also suitable for a variety of aircraft parts.
High Performance Plastics
Although metal parts are more widely used in the functional structure of aircraft, many interior components are made of polymer materials. These materials are much lighter than metals. They are used to produce parts such as interior panels, ventilation ducts, aircraft doors, wiring ducts, bearings, etc. These are lightweight, strong aerospace-grade plastics that meet aerospace flame-retardant regulations.
Aerospace CNC machining creates strong, lightweight and complex plastic parts for the aerospace industry. Manufacturing these parts involves the use of PEEK and other high-performance polymer materials. Similar to metal machining, aerospace machining provides the high precision required for polymer-based aerospace applications.
Working Principles of Aerospace CNC Machining
Aerospace CNC machining works on the basis of computer numerical control (CNC) technology. Here are the basic steps involved:
Design And Programming: Engineers use computer-aided design (CAD) software to create a three-dimensional model of the part. They write CNC programs that contain detailed information about the machine tool's motion, cutting speeds, and cutting paths. These programs instruct the machine tool to precisely machine the shape and size required by the design.
Machine Setup
The written program is loaded into the controller of the CNC machine. Next, the machine needs to be properly set up, which includes adjusting the position of the fixture, tool, and workpiece to ensure that they are in the correct machining state.
Machining The Part
When the machine and workpiece are ready, the CNC system will control the machine to cut the workpiece according to the path defined in the program. This usually involves the rotation and movement of the tool to remove material and form the desired shape.
Quality Control
During the machining process, the operator monitors the quality of the part and takes necessary measures to maintain machining accuracy. This may include measuring the size and surface quality of the workpiece.
Finishing And Inspection
After machining is completed, the part will undergo final inspection and testing to ensure that it meets the design specifications and quality standards. This step is a key step in ensuring that each part meets the highest quality requirements before leaving the factory.
Precision CNC machining is essential for manufacturing high-quality aerospace parts. The aerospace industry has strict safety controls and high production standards for CNC machined parts. Every detail of these parts requires the most stringent tolerances, dimensions, and performance requirements. This precision machining helps ensure that aerospace parts do not fail in flight.
For example, fuselage sections and aircraft landing gear components require extremely tight tolerances and precision. All tiny details must be considered and incorporated with extreme precision to ensure their proper function.
Any slight error or machining defect in a commercial aircraft, cargo plane, or fighter jet can result in huge losses. Aerospace machining companies ensure that CNC aerospace parts meet standard requirements.
CNC machine shops can provide prototypes and precision machined parts for the aerospace industry using advanced CNC machining equipment. Efficient CNC machining technology helps achieve tolerance levels up to 0.002 mm, creating plastic and metal parts that meet aerospace standards. Advanced post-processing and inspection systems ensure that your aerospace prototypes and parts meet the required standards.

CNC rapid prototyping allows aerospace companies to minimize production costs and overall company expenses since it eliminates the need to invest in tools. More importantly, it helps aerospace companies meet regulatory requirements.
The evolution of technology has made aerospace part designs become more and more complex. bulkhead (which is the part that keeps the crew safe during their journey) is domed near the heat shield and features pockets normal to its surface. aircraft landing gears and fuselage sections are massive, feature meticulous details, and require extremely tight tolerances.
5-axis CNC milling machines are responsible for manufacturing these complex parts. They can achieve angles that are most likely impossible to achieve using a 3 or 4 axis machine.
Present-day CNC machines used in the aerospace industry now include Artificial Intelligence (AI) and Machine Learning software. This allows aerospace companies to analyze accurate production metrics, achieve aerospace part production goals and improve the quality and consistency of machined aerospace parts.
Like in many other industries, aerospace companies rely on many third-party manufacturers for different parts. These parts typically require tight tolerances and must precisely fit together with parts created in other machine shops and therefore room for geometrical errors during manufacture is entirely eliminated.
Through accurate CNC machining, aerospace companies are able to create precise parts with exact specifications, ultimately achieving the smallest of tolerances.
