What is Reverse Engineering?

Reverse engineering refers to the transfer of real-world components into digital geometry models. The method delivers actionable quality data for product release, process optimisation and root-cause analysis.

Scientific background

Methodologically, the procedure relies on standardised workflows covering data acquisition, segmentation, feature extraction and evaluation. Core elements include volume segmentation, surface extraction and CAD reconstruction. Meaningful results only emerge from traceable criteria and defined acceptance limits.

Relevant key metrics

Detection limit and misclassification risk for the relevant failure modes.
Repeatability of the evaluation for identical input data.
Relationship between indicators and functional load zones / specifications.

Standards and thresholds

Standards: ISO 1101:2017, ISO 5459:2024 and VDI/VDE 2630 Part 1.2:2018-06.
Typical thresholds (in practice): Mesh/CAD deviations within defined target or tolerance bands; complete data capture of critical functional surfaces.
Validity: Acceptance criteria depend on intended use (replication, optimisation, repair) and the legal framework.

Application in industrial practice

Data-based release decisions during ramp-up and series production.
Early detection of deviations with cause-oriented prioritisation.
Improved customer and supplier communication through objective CT reports.
