35. Robotic Tolerance Architecture
Stable section ID: S05-CON-011-SECTION-36 · 29 content blocks
Robotic compatibility shall be based on an end-to-end tolerance architecture rather than isolated component dimensions.
The tolerance budget may include:
- Manufacturing tolerance.
- Assembly tolerance.
- Node and Interface tolerance.
- Component deformation.
- Thermal movement.
- Moisture-related movement.
- Foundation settlement.
- Robot positioning accuracy.
- Localization uncertainty.
- Sensor accuracy.
- End-effector compliance.
- Tool wear.
- Calibration uncertainty.
- Temporary structural deflection.
The architecture shall distinguish among:
- Geometric clearance.
- Alignment tolerance.
- Capture tolerance.
- Locking tolerance.
- Functional tolerance.
- Inspection tolerance.
- Removal tolerance.
- Digital-model tolerance.
Interfaces should use coarse-to-fine alignment so that the robot is not required to provide all final precision directly.
Tolerance accumulation shall be evaluated across the complete load path and assembly sequence. A component that complies individually may still fail to assemble when combined variations exceed the Interface’s capture range.
Robots shall not force nonconforming components into position unless a specifically approved correction process exists. Excessive force, unexpected displacement, or repeated failed insertion shall trigger inspection.
Measured as-built deviations shall be recorded where they affect future robotic access, replacement, or Digital Twin accuracy.
