Aerospace CNC Machining: Custom CNC Prototypes and Parts

In today’s extremely competitive environment, the aerospace industry is constantly looking for innovative solutions to meet extremely harsh working environments and highly complex requirements. Custom CNC prototype and part manufacturing, as an advanced manufacturing technology, plays a vital role in the aerospace field.

This article will delve into why custom CNC prototypes and parts are so important in the aerospace industry, along with their advantages, applications, and manufacturing processes.

Aerospace CNC Machining

Why choose CNC machining?

CNC machining technology plays an important role in the aerospace field. Below we will explore in detail why CNC machining has become the manufacturing technology of choice for aerospace engineers.

High precision and tolerance

Aerospace parts require highly accurate manufacturing to ensure their performance and safety. CNC machining enables extremely high manufacturing accuracy, and manufacturing tolerances can reach very small ranges, usually in the micron level. This is critical for aerospace components that require precise fit and alignment.

Material diversity

Aerospace applications have a variety of material requirements, requiring high temperature resistance, corrosion resistance, high strength and other characteristics. CNC machining can be applied to a variety of metal and engineering plastic materials, allowing engineers to select the most suitable materials to manufacture parts according to their needs.

Complex geometry

The geometry of aerospace parts is often complex and variable, requiring highly accurate machining. CNC machining enables the machining of complex shapes through multi-axis motion and advanced tool path planning, whether it is propeller blades, turbine blades or other complex structures, it can be precisely manufactured.

Iterative design and rapid prototyping

CNC machining provides engineers with the ability to quickly manufacture parts and quickly produce prototypes and samples for testing and validation. This allows engineers to make iterative designs, quickly adjust and optimize part designs, and thus shorten product development cycles.

CNC machining technology for aerospace industry

CNC machining is a highly versatile manufacturing process. While there may be slight differences in how the device is set up, with this technology, engineers are able to manufacture CNC machined parts with different shapes and geometry, greatly enhancing the functionality and applications of these parts.

CNC machining technology uses computer-controlled precision machine tools, such as milling machines, lathes, drilling presses, etc., to cut, process and form materials. The following are several common CNC machining methods in the aerospace industry:

milling

Milling is the removal of material from the surface of the workpiece by rotating the tool to obtain the desired shape and size. In aerospace, milling is often used to manufacture complex components such as engine housings and flight control components.

turning

Turning is the process of placing a rotating workpiece on a lathe and changing the shape of the workpiece through the movement of the cutting tool. This is often used to make shaft, threaded and cylindrical parts, such as aircraft engine parts.

drilling

Drilling is the creation of holes or holes by pushing the tool into the surface of the workpiece. In aerospace, drilling is used to make various components, such as propeller blades and sensor mounts.

wire-cut

Wire cutting uses electric spark discharge technology to cut the workpiece through a thin wire to create complex shapes and contours. This is useful when manufacturing high-precision components such as turbine blades and pneumatic housings.

Aerospace CNC machining applications

Milling and drilling combined machining

This is the combination of two processing methods, milling and drilling, to complete multiple operations in the same process. This is often used in aerospace to make complex connections and brackets.

grinding

Grinding is the grinding tool to smooth the surface of the workpiece to obtain higher accuracy and finish. This is very important when manufacturing high-precision bearings and cycloidal mechanisms.

Aerospace CNC machining applications

Aerospace CNC machining plays an important role in various application areas, and the following are some common application areas:

Engine component

The aero engine is the heart of the aircraft and its parts need to be manufactured with high precision to ensure the performance and longevity of the engine. CNC machining can manufacture high-precision engine components such as turbine blades and combustion chamber parts.

Structural part

Aircraft structural components need to be strong and lightweight. CNC machining can manufacture aerospace chassis parts, wing structures, etc., to meet the load and vibration requirements of the aircraft in flight.

Spacecraft component

Spacecraft need to withstand extreme temperatures and vacuum environments, and their parts manufacturing requires extreme precision and endurance. CNC machining can manufacture satellite parts, detector parts, etc., to ensure the reliability and performance of spacecraft.

Aerospace CNC machining parts

Instrument and equipment

The aerospace field requires a variety of instruments to monitor and control flight conditions. CNC machining can manufacture sensor parts, dashboards, and more, ensuring that pilots and operators get accurate data.
