Aerospace Machining Is Evolving: Everything You Need To Know

The AS9100 specification is one of the most stringent quality criteria that CNC machined components must meet in the aerospace sector.A manufacturing method must be in place to support components that have been designed and tested to meet all requirements. Precise aerospace CNC machining is absolutely necessary in this situation.

Aerospace Aircraft, space shuttles, and other aerospace applications rely on components made via CNC machining. For example, aviation components come in a vast array of shapes and sizes; these components are utilised in the manufacturing of seats, oxygen generating systems, filters, and many more.

When it comes to aircraft, how may CNC machining be used?

The plane’s engine and wings are the first components that come to mind when you think of an aeroplane. A Boeing 747 contains more than 6 million parts, which should give you an idea of scale and highlight how critical it is to be exact with each and every one of them.

Several aerospace-related applications make use of CNC machining. The following items can be made from this:

  • Positions in spaceships and aeroplanes
  • Applications involving shafts for power transmission
  • Parts of oxygen production systems
  • Parts of the valve
  • Connectors for electrical devices
  • Durable missile casings
  • Filter structures for air and liquid that are complex

The application of computer numerical control (CNC) machining in aerospace has a somewhat distinct emphasis:

CNC for use in aerospace

The manufacturing of an aeroplane is characterised by its meticulous attention to detail. All components must be manufactured with the utmost precision if this aircraft is to be used as a combat jet, a passenger airliner, or a freight plane. Aircraft engines are responsible for properly processing and using fuel to keep planes in the air for the necessary duration. The cockpit, even without the engine, is critical, with many little parts and their interconnections performing critical functions during flight. Aircraft that consistently perform to a high standard and satisfy stringent safety rules are the result of the combined efforts of all of its parts.


A rocket or spacecraft’s overall design is comprised of countless intricate and crucial parts. It is absolutely mind-blowing to think about constructing a spaceship to endure the rigours of space flight. Due to the meticulous nature of this production process, CNC machining has emerged as the gold standard for safety and durability due to its high requirements.

Aerospace CNC machining uses what kinds of materials?

Aerospace CNC machining requires materials that are both lightweight and robust. You may basically classify materials into two broad categories: those that are strong and lightweight (like aluminium) and those that are neither.

Materials that are not heavy

Aerospace manufacturing relies heavily on the weight and strength of its components. For this reason, steel is not really a lightweight metal, despite its reputation as a robust metal. A less efficient and heavier plane would result from using steel. Because of their strength and light weight, aluminium alloys and titanium are the materials of choice for both the exterior and inside of aeroplanes.

Superbly performing polymers

One use of computer numerical control machining in the aerospace industry is the production of lightweight, complicated plastic components. It provides the kind of precision needed for these kinds of uses, making components for things like bearings, electrical conduits, interior wall panels, doors, and ventilation ducts.

Using top-notch materials and quality CNC machining, the basis for any spaceship or aircraft may be built from either metal or plastic. The aerospace industry relies on this, and CNC machining technologies can’t compare.

Aerospace CNC machining’s advantages

CNC machining offers numerous advantages to the aerospace sector, such as:

Exquisite level of achievement

Aerospace components must meet rigorous standards to prevent malfunction. CNC machining consistently produces high-quality results even when working with challenging materials.

Natural lightness

The aircraft industry is always looking for ways to make their equipment lighter. Using computer numerical control (CNC) machining, it is possible to create sturdy and lightweight structures and components.


In the aircraft sector, accuracy and precision are paramount. Computer numerical control (CNC) machining provides a precise method to enhance tight tolerances and decrease the likelihood of manufacturing mistakes. There is absolutely no space for human mistake in this highly precise engineering. This is of the utmost importance in this field, as aircraft are used for extended periods of time in flight and remain in service for numerous years.

Diverse and intricate components

In the aircraft business, precision is of the utmost importance for every component. A method like CNC machining is necessary to ensure the stability and consistency of performance when dealing with components that span a wide range of sizes, shapes, and levels of complexity.

Affordable process

After considering all of the advantages, CNC machining becomes a cost-effective procedure for the aerospace sector in the long run. Reduced material waste and fewer parts with flaws mean less time and money spent fixing them. Profitability is enhanced by lowering the price-per-part and achieving rapid and precise production.

Robust components, frequently with intricate geometries, are essential to the aerospace industry’s reliance on high-quality part production. Component parts that meet these specifications can be quickly and accurately manufactured by Rotec’s CNC machining capabilities. Producing parts for individual uses or larger production runs requires this level of precision.
