• Lack of machining experience: CNC machining involves practical experiences such as tool path planning and setting of cutting parameters. Models generated by AI may ignore the feasibility of machining (such as tool interference and stress concentration) and require calibration by engineers.
• Material property adaptation: JS company processes more than 50 materials (metals, composites, etc.), each with processing characteristics that make it difficult for AI to fully grasp the impact of material microstructure on shaping, relying only on material selection recommendations from engineers.
• Quality control boundaries: In the JS case, for example, 98% of orders were delivered on time, relying on engineers to adjust processing errors in real time. Currently, AI cannot dynamically respond to variables such as machine tool state, ambient temperature and humidity.

3.The manifestation of collaborative value

Algorithms are tools, experience is irreplaceable

The practical logic of JS: Using generative AI for initial design exploration (such as quickly generating multi version shell structures), followed by engineers screening and optimizing based on CNC process constraints (such as JS's ±0.005mm tolerance), material properties (such as titanium alloy processing temperature), and customer case experience (such as batch consistency of automotive molds).

Generative AI can improve design efficiency, but the core of machining CNC experience and quality control-still needs to be led by senior engineers. The success of JS demonstrates that the human-machine collaboration model (AI assisted+manual verification) is the most optimal solution for current manufacturing.

What are the difficulties in processing the irregular cooling chamber of rocket nozzle?

Processing difficulties

1.Treatment of complex irregular structures

• Rocket nozzle cooling chamber usually has complex geometrical characteristics such as thin wall, variable cross section and small flow channels. Traditional CNC machining is prone to interference or surface quality defects. Accurate path planning needs to be achieved through multiaxis coupling,such as five-axis machining.
• JS company can effectively address these challenges with its high-precision five-axis machine tools.

2.Characteristics of high-temperature alloy materials

• Refractory materials with high hardness and poor thermal conductivity, such as titanium alloys, are commonly used in Cooling chambers. In the process, it is easy to appear tool wear, cutting force, etc. 
• JS company uses professional coated cutting tools to ensure the stability of processing by optimizing parameters such as cutting speed and feed speed. The precision of the processing can be ±0.005mm, satisfying strict tolerance requirements.

3.Cleanliness and consistency of internal flow channels

• The interior of the cooling chamber needs to be kept absolutely smooth to avoid fluid resistance, as traditional machining tends to create residual burrs or debris. 
• JS company uses high-pressure water jet, electrolytic polishing and other post-processing techniques, and works with CNC online detection system to ensure the interior quality of the cavity complies with aerospace standards.

4.Thermal deformation control

• Long-term hightemperature treatment will lead to thermal expansion of the material, affecting size accuracy. Through constant temperature workshop, real-time temperature compensation algorithm and segmental processing strategy.
• JS company can control the the thermal deformation error to 0.01 mm.
