Current capabilities and capabilities to be supplemented
Partially reusable
Requires calibration, synchronization or integration
The light point detection front-end or timing statistics module can be reused, but the project still needs to add geometric calibration, time synchronization, motion compensation or equipment system integration.
Gaps in this scenario:Point laser distance calibration, collinearity/synchronization and reference spacing models on both sides are required; the height of a single point is not directly equal to the thickness. Fixture loads and boundary conditions must be recorded. Shape displacement and electrochemical state are inspected separately
Route-level gaps:Point laser distance calibration, collinearity/synchronization and reference spacing models on both sides are required; the height of a single point is not directly equal to the thickness
"Partially reusable" only describes the relative development volume and does not constitute a commitment to accuracy, tempo, stability or delivery time.
Verification methods and acceptance prerequisites
Use standard thick slices and warped samples to compare, and change the inclination angle and motion phase to check the differential error. Cross-reference of standard parts, displacement tables and contact gauges
