knowledge nodes of thread manufacturing must be interconnected and cannot be independent of each other.

UGMIC's thread technology consultant recommends establishing the following "core problem-solving approach": 

Problem Symptoms → Operating Condition Inspection → Judgment → Threading Tool Selection → Threading Tool Parameter Optimization → Verification

UGMIC thread knowledge graph establishes a complete thread knowledge framework based on eight core nodes:

① Thread standards and specifications (ISO, BS, DIN, ANSI, ASME, JIS, CNS, CN)

↓

② Material of threaded workpieces (non-ferrous metals, ferrous metals, high-temperature alloys, other non-metallic materials)

↓

③ Thread manufacturing conditions × Tap usage parameters (adjusted according to actual conditions)

↓

④ Tap material(SC, WC, Hc) × Tap structure (StT, SpT, PoT, RFT) × Workpiece material parameters (#O, #C, #C, #BC, #B, ... etc.)

↓

⑤ Internal thread manufacturing problems (chip blockage, chip jamming, chip adhesion, continuous chipping at the bottom of the hole, burrs, scale, vibration marks)

↓

⑥ Problems with internal thread tapping (heat treatment deformation, shrinkage, shrinkage springback, machining stress deformation, residual stress deformation, electroplating allowance, paint baking allowance)

↓

⑦ Thread function testing issues (thread gauge inspection, plug gauge inspection, torque test, tensile test, crack test)

↓

⑧ Tap usage parameters (equipment operating condition records, program, speed, feed, internal cooling, external cooling, etc.)

↓

⑨ Tap optimization solution (It is recommended to address the above issues by optimizing relevant peripheral conditions and thread cutting tools).

↓

⑩ Experimental verification of tap problem optimization (establishing a standardized record-keeping scheme)

The final result is:

Thread standards → Threaded workpiece materials → Thread manufacturing conditions → Threading tools- taps → Machining → Inspection → Problems → Optimization → Validation → Standardization
