What are the characteristics of aerospace parts processing

The aerospace industry has always been one of the pinnacles of technology and engineering, and it relies on precision-manufactured aerospace parts to ensure highly reliable and safe aviation and space systems. The manufacture of these parts involves challenges of material selection, high precision processes, and complex engineering requirements. In this article, we will explore the knowledge of various aspects of aerospace parts machining.

1. Material requirements

The manufacture of aerospace parts begins with specific material requirements. These parts typically need to have high strength, low density, high thermal stability, and corrosion resistance to cope with extreme operating conditions. Common aerospace materials include:

a. High strength aluminum alloys

High-strength aluminum alloys are ideal for manufacturing aircraft structural parts due to their light weight, corrosion resistance, and ease of machining. For example, 7075 aluminum alloy is widely used in the manufacture of aerospace parts.

b. Titanium Alloys

Titanium alloy has excellent strength to weight ratio and is widely used in aircraft engine parts, fuselage components and screws etc.

c. High Temperature Alloys

High-temperature alloys maintain strength and stability at high temperatures and are used in engine nozzles, turbine blades and other high-temperature parts.

d. Composite Materials

Carbon fiber composites are excellent in reducing structural weight, increasing strength and reducing corrosion, and are commonly used to make shells for aerospace parts and spacecraft components.

2. Process requirements

The manufacture of aerospace parts requires highly sophisticated part machining processes to ensure performance and reliability. For example, CNC machine tools; CNC machine tools are the core tools for machining aerospace parts. They are capable of performing CNC milling, CNC turning, drilling and other operations with high precision control. Secondly there are heat treatment, welding and riveting, surface quality these all directly affect the aerospace parts hardness, strength, wear resistance, high load resistance, high temperature resistance. At the same time in the axial precision, thermal stability and other aspects need to be extremely high requirements.

3. Processing difficulties

Aerospace parts processing is full of challenges, mainly in the following aspects:

a. Complex geometry

Aerospace parts usually have complex geometries and require high precision machining to meet design requirements.

b. Super alloy machining

Machining of high temperature alloys is difficult and requires special tools and processes to handle these hard materials.

c. Large Parts

Spacecraft parts are usually very large and require large CNC machine tools and special machining equipment.

d. Quality control

The aerospace industry has very high requirements for part quality and requires strict quality control and inspection to ensure that each part meets standards. Precision and reliability are key in aerospace parts machining. A deep understanding and fine control of materials, processes, precision and machining difficulties are the key to manufacturing high quality aerospace parts.
