Details

The requirements for machining metal components for aircraft in the aviation industry are extremely stringent.Here is a summary of some key requirements:


1.High-Performance and Precision

• Aviation products require high performance and precision due to their unique usage environments,demanding high reliability and product performance.Materials such as titanium alloys and composite materials are commonly used in processing,and most aviation parts have complex geometric shapes with high manufacturing precision requirements and measurement standards.


2.Lightweight and Large-Scale Design

• Aviation products like engine compressor rotors,aircraft engine blades,entire cabin sections,landing gear,casings,and antenna covers extensively use titanium alloys,high-strength materials,and high-temperature alloys.Composite materials are also widely used in aircraft fuselages and wings.These materials are used to ensure that the aircraft has both high strength and low weight,with large-scale structural processing to reduce unnecessary connections and increase part rigidity.


3.Digitalization and Intelligent Manufacturing Processes

• Advanced manufacturing technologies such as digital design and manufacturing of aviation product components,CAPP and CAD/CAM software applications,and digital workshop management systems like MES based on CNC machining workshops are发展方向.


4.High-Speed Machining Technology

• High-speed cutting technology offers significant advantages like high processing efficiency,low cutting load,less heat input into the workpiece,and minimal workpiece deformation.It has been successfully applied in the aviation industry since the mid-1990s and has achieved significant economic benefits.


5.3D Printing Technology

• 3D printing,or additive manufacturing,is characterized by low cost and short cycles,meeting the processing needs for large,thick,and complex cavities,as well as extremely complex-shaped medium and small parts.It has become one of the important indicators of the advanced manufacturing process in modern aerospace and other products.


6.Automation and Intelligent Manufacturing for Long-Aspect-Ratio and Difficult-to-Machine Thin-Walled Shell Parts

• Solutions for automating and intelligently manufacturing parts with a large length-to-diameter ratio(L/D>10-15),diameter(80-120mm),and wall thickness(1-15mm)made from materials like stainless steel,aluminum alloys,titanium materials,and high-strength steel are crucial.


7.Material Selection and Preparation

• Suitable materials for aerospace parts are chosen based on factors such as strength,weight,and thermal performance.Raw materials(usually metals or engineering plastics)are then cut to size and secured to the CNC machine's worktable for machining.


8.Adoption of CNC Machining

• CNC machines execute machining operations according to programmed instructions,precisely removing material from the workpiece to achieve the desired shape,size,and surface finish.This may involve various processes such as milling,turning,drilling,or grinding,depending on the complexity of the part.


9.Tooling and Tool Change

• The selection of tools and the frequency of tool changes are critical in the machining process to maintain efficiency and part quality.


10.Compliance with Civil Aviation Regulations

• Applicants must submit applications for part manufacturer approval in the prescribed format and manner,along with detailed design and manufacturing information to ensure compliance with civil aviation regulations.


11.Material Conformity

• It is necessary to ensure that the materials used conform to the technical specifications in the design and that all necessary inspections and tests are conducted to verify the design's compliance with applicable airworthiness requirements.


12.Additive Manufacturing in Aerospace

• Additive manufacturing technologies,including Selective Laser Melting(SLM)or Fused Deposition Modeling(FDM),are increasingly used to produce complex aerospace parts that are difficult to manufacture using traditional methods.


13.Aerospace Metal Stamping

• Metal stamping is essential for producing high-precision parts such as panels,brackets,and structural components required for aircraft manufacturing.Known for precision and consistency across multiple parts,this method is cost-effective and scalable,especially for mass production.


14.Aerospace Waterjet Cutting

• Waterjet cutting is used for cutting complex shapes and designs from materials like metal and composites with high precision and little to no heat-affected zone,which is beneficial for aerospace applications where material integrity is crucial.

Meeting these requirements ensures that the metal components used in aircraft are reliable,safe,and perform as intended,contributing to the overall performance and safety of aviation vehicles.
