CNC Machining in the Aerospace Industry - 4 Key Applications

1. CNC Machining and Sheet Metal in the Aerospace Industry: 4 Key Applications CNC (Computer Numerical Control) machining is a cutting-edge process with the power to streamline production in working environments on all scales. Computer software is programmed to handle machinery and tools (lathes, mills, grinders, etc.), performing specific movements to achieve diverse goals. This automation and flexibility enable manufacturers to reduce the manpower required to produce/refine materials, streamlining one area to reinforce another. And that’s as crucial in the aerospace industry as any other. Especially in the production of sheet metal, one of the core materials in aerospace manufacturing. The following four key applications reveal why CNC machining and sheet metal are so important to the industry. 1. Performing Stability Checks and Refinements to Prevent Vibration-related Damage Flight is a complex, rigorous process for almost any vehicle. Even the most cutting-edge planes must be designed for maximum resilience to the forces weighing against them while airborne.

2. High-frequency vibrations are an obvious, consistent aspect that must be considered during the manufacturing process. It’s fundamental that materials and fixtures are capable of withstanding the immense pressure they will be under while in the air. Using vibe plates to simulate the effects of flight is one of the most useful applications CNC machining offers to the aerospace industry. Mass production of essential fixtures means vibration tests must be ongoing and consistent to ensure uniform standards. 2. Producing Bespoke Interface Panels for Cost-effective Fabrication Sheet metal makes a cost-effective choice for fabrication of interface panels, which can be combined with standard components as required. Interfaces obviously play a key role in the aerospace industry and must provide reliable functionality. However, manufacturers are required to keep costs low to ensure output remains at the requisite level, which is why leveraging sheet metal is a valuable option. Quality control is, of course, critical, as certain metal alloys may face a risk of becoming cracked after formation. 3. Keeping Valuable Components Secure and Resistant Sensors (such as cameras) must be protected when in flight. These often-fragile products can be prone to damage, even to a small degree, which can have a knock-on effect on other components. Corrosion is a common concern and protective exteriors must be up to the task. Producing machined housings with CNC machining helps reinforce sensors and extend their lifespan. Anodizing is an effective way to increase durability of housings, but it can reduce the strength of certain aluminium alloys. Manufacturers must exercise caution to achieve the most resilient results.

3. 4. Maximizing the Effectiveness of Assembly Tooling on a Larger Scale Assembly tooling is a complex process that demands precision and efficiency, which is why Delrin is one of the most commonly-used materials. Delrin is generally cost-effective and simple to use. It’s robust enough to keep components safe in demanding applications and is known for its reliable performance. Manufacturers can use CNC machining to complete assemblies in large quantities without compromising on quality, provided the right materials are utilized in the first place. CNC machining and sheet metal can drive greater productivity and more satisfactory results in the aerospace industry. Manufacturers should take note of these four applications and try integrating them into their own processes.
