Material and loading
Define the material designation, service loading and grain-flow requirements.
Factory Tour · Process principles
Choose the forming route around the load-bearing part.
Grade, grain flow, heat treatment and finished geometry belong in the same review. Compare closed-die and open-die routes around the proposed blank and the final machined interfaces.
The forming route and validated result depend on material condition, geometry and loading requirements.
Process relationships
- Load & material
- Forming route
- Heat treatment
- Finished geometry
Connect each stage to the finished-part requirements.
Define the requirement
Bring the drawing, material and acceptance inputs.
Blank and finished part
Provide the forging type, blank geometry, machining allowance and dimensional datums.
Condition and testing
Specify heat treatment, mechanical properties, test orientation and required NDT.
Process principles
Two forming routes, different part definitions.
Review the tooling and stock requirements before deciding how the part should be formed.
Closed-die forging
Drawing-defined geometry is reviewed with shaped tooling, flash and machining allowances.
- Tooling and blank
- Formed geometry
- Critical machining interfaces
Open-die forging
Larger or simpler sections are reviewed around the stock, deformation route and subsequent machining.
- Stock and section
- Forming route
- Finished journals or faces
Heat treatment links the stages
Agree the material condition and thermal route with the final mechanical acceptance.
Machine only after defining the interfaces
Connect the forging envelope and machining stock to final bearing, attachment and locating features.
Verification and records
Verify condition as well as shape.
Dimensional acceptance
Review as-forged geometry and measurement of the machined surfaces.
Mechanical records
Agree chemistry, hardness and mechanical tests for the specified material condition.
Soundness and traceability
Define any required UT, grain-flow verification, heat-treatment charts and first-article records per project.
Project review
Connect the route to your requirement.
Send the material or drawing definition, intended use and the acceptance records needed for review.
