What does CNC mean in AIRCRAFT & AVIATION

CNC stands for Computer Numerically Controlled and describes an automated process, whereby a machine is controlled by computer software. It is used to produce items in manufacturing such as parts and components, with great accuracy and repeatability.

CNC machines offer numerous benefits over traditional manufacturing methods. These include a reduction in labor costs, improved accuracy, increased production speeds, greater design flexibility, improved safety, better product quality control and a longer lifespan for the machines.

CNC machining can be used to machine virtually any material including metals such as aluminum and steel, plastics, composites and other materials that can hold up under the stresses associated with machining.

The accuracy of CNC machines differs depending on the type of control system used. Generally speaking however, some models boast accuracies of up to 0.005mm which is considerably more accurate than manual processes.

This depends largely on factors such as the degree of complexity in product design and type of material being machined; but generally speaking much faster production rates are achievable than through traditional machining methodologies.

As with any form of machinery there are inherent risks associated with its operation; therefore it’s important that all operators adhere strictly to recommended safety procedures including wearing protective clothing where applicable. Additionally personnel should not work alone in close proximity to a running machine and regular maintenance checks must also be conducted.

Yes – specialist training is typically required by most employers prior to allowing personnel to operate these machines. Most manufacturers offer courses specific to their products and it’s important that operators fully understand how the function before undertaking any tasks.
