Why Precision Builds Fail
Precision breaks when physics is left unmanaged.
Failure Signals
Small drift becomes big failure in assembly.
Thermal instability
Heat changes dimensions between stages.
Tolerance blown
Metrology gaps
Critical faces lack verification depth.
Proof missing
From Assumed Precision to Metrology-Locked Precision
Precision holds when metrology and thermal control are explicit.
Typical Precision Path
- Input: tolerance target without metrology scope
- Process: thermal drift untracked
- Result: late assembly failure
Geppetto Managed Precision
- Input: critical features tiered
- Process: CMM + thermal control locked
- Result: assembly-ready fit
