The CNC Machining Process For Aerospace Components

An error on an aerospace component will, ultimately, result in an immense safety hazard. For that reason, it is essential that human errors are prevented during the machining process, which will, in turn, reduce the risk of a faulty part being produced.

The CNC Machining Process is capable of fabricating the complex aerospace components that have intricate geometries. Multiple manufacturing procedures can be performed on a part simultaneously with a CNC machine. Because of this, the machinery has the ability to manufacture specific specifications and significantly tight tolerances. In the realm of aerospace, this is immensely important, as aircrafts and space shuttles often have many parts with odd and precise geometries.


    Here at P4Swiss/Lindel CNC Machining, we particularly specialize in the precision manufacturing of aerospace components. Our facility strictly follows an advanced project management system for each machining project.

    Production Highlight: Aerospace Component

    A unique aeronautical part that our machine shop recently manufactured will be soaring through the solar system soon.

    Aerospace components are expected to successfully function and operate in extreme environments. That is why attention to detail cannot be spared, especially when it comes to Aerospace CNC Machining.

    Our facility can guarantee aerospace components that will pass industry standards. In addition to that, we can assure you that your machined parts and data will be properly handled and safely secure.

    How We Meet Your Aerospace Manufacturing Needs:

    • Machined components are produced in an ISO 9001:2015 and AS9100D quality environment
    • 3-axis, 4-axis and 5-axis CNC milling is offered for precise machined parts
    • Projects are produced with a Gibbs/CAM system to precisely machine the most intricate geometries
    • CNC turning and live tooling are both available

    We received the opportunity to manufacture a component for the Aerospace Industry, in conjunction with the University of Berkeley in California. This component is known as a prototype for the NASA space program. As a matter of fact, this aerospace component will be going to outer space for an unidentified mission. With that being said, even the smallest deviation had to be prevented, in order to avoid a safety hazard. To accurately manufacture this intricately designed aerospace part, the 5-axis CNC Machining Process was certainly required.

    What Is The 5-Axis CNC Machining Process?

    More companies prefer the 5-axis CNC machining process, due to the continuous precision and exact accuracy that can be assured on a project.

    CNC refers to a Computer Numerically Controlled operation. In other words, the machining process is completely controlled by computer programs. Therefore, the cutting tools and the cutting technique of the machine can be precisely guided.

    The traditional 3-axis CNC machining method operates with a cutting tool that can move in three separate directions (X, Y and Z axes). Typically, a 3-axis CNC machine is used for the creation of relatively simple shapes and features. However, when it comes to a more intricate and complex component, additional axes of movement are going to be necessary.

    Not only does the 5-axis CNC machine contain the three linear axes of motion, but also two rotational axes, as well. As a result, the cutting tool is able to move in five separate directions.

    1. The X-axis is a horizontal movement from left to right
    2. The Y-axis is a horizontal movement from front to back
    3. The Z-axis is a vertical movement that moves up and down
    4. The A-axis rotates around the X-axis
    5. The B-axis rotates around the Y-axis

    Benefits Of A 5-Axis CNC Machine

    The 5-Axis CNC Machining Process provides several significant benefits to the aerospace industry. Here are some of the key advantages:

    01. More Complex Geometry

    Aerospace components often have intricate and complex shapes that would, otherwise, be challenging to produce when using the traditional machining methods. On a 5-axis CNC machine, complex geometries can be successfully fabricated without the need for multiple setups. This is going to reduce the chances of an error transpiring and improve the overall accuracy.

    02. Reduced Setups

    With the traditional CNC Machining Process, complex parts require multiple setups to produce the different features. However, on a 5-axis CNC machine, the workpiece can be manufactured in multiple directions simultaneously. This is going to reduce the number of setups that are necessary, essentially guaranteeing shorter production times and decreasing the chances of an error transpiring.

    03. Improved Accuracy

    Manufacturing a workpiece along five separate axes - the X, Y, Z and two rotational axes - enables precise machining from a variety of angles. This accuracy is critical for aerospace components that demand tight tolerances and minimal deviations.

    04. Reduced Tool Interference

    Aerospace parts generally have intricate features, which can require tool access from numerous angles. The 5-axis CNC machines are able to adjust the tool angles and orientations dynamically. This is going to minimize tool interference and provide a machining process that is smooth and uninterrupted.

    05. Enhanced Surface Finish

    Aerospace components typically require excellent surface finishes, in order to properly meet aerodynamic and aesthetic requirements. With the 5-axis CNC machining process, smoother surface finishes can be produced. This is because the tool angles can be adjusted and the need for additional finishing processes is minimized.

    06. Reduced Lead Times

    5-axis CNC machining can guarantee reduced lead times, which is due to:

    • The ability to create complex parts in only one single setup
    • The improved efficiency of the machining process

    This can positively impact your project schedule, especially the projects that are part of a new aircraft or spacecraft.

    07. Prototype Development

    5-axis CNC machining is valuable for rapid prototyping in the aerospace industry. In essence, this CNC machining process helps engineers successfully produce prototypes with complex geometries quickly, by facilitating design validation and iterative improvements before moving to full-scale production.

    08. Less Manual Intervention

    The automation capabilities of 5-axis CNC machining is going to minimize the need for manual intervention throughout the machining operation. This ultimately results in:

    • Consistent quality
    • Reduced chances for human error
    • Improved safety for operators

    09. Multi-Sided Machining

    Aerospace components typically have various features on multiple sides that require machining. The 5-axis CNC machinery enables machining on multiple sides of a part simultaneously, without the need for repositioning. For that reason, the efficiency and accuracy is significantly enhanced in the 5-axis CNC Machining Process.

    Aerospace CNC Machining

    Overall, there are a variety of benefits to using a 5-axis CNC machine for parts in the aerospace industry, all of which are critical for producing safe and efficient aerospace components.

    • Increased productivity
    • Improved quality
    • Greater design flexibility
    • More complex parts
    • Tighter tolerances
