How long does it take from scanning to obtaining the final inspection report?
Overview of the inspection timeline
The total time from scanning to receiving the final inspection report varies depending on the part's complexity, size, and required precision. In most production environments, the complete workflow—including surface preparation, data acquisition, processing, and reporting—can take from a few hours to several days.
For typical precision components produced through CNC machining or precision machining, a standard non-destructive contour inspection and report generation are completed within one work shift (8–12 hours). However, large-scale or aerospace-grade parts, which involve multiple multi-axis machining operations or specialized alloys, may require more extensive post-processing and validation, extending the cycle to 2–3 days.
Step-by-step process duration
1. Surface preparation and fixturing (1–3 hours)
The initial stage involves cleaning, applying temporary matte sprays to reflective surfaces, or adjusting finishes through methods such as sandblasting and electropolishing. This ensures stable optical performance and reliable contour data. Fixture alignment and environmental stabilization may also add setup time.
2. Scanning or measurement acquisition (1–6 hours)
Depending on the part geometry and size:
Compact parts (under 300 mm) scanned by structured light or CMM may take 1–2 hours.
Medium-sized components, such as turbine housings or complex assemblies, require 3–5 hours.
Large-scale structures inspected via laser tracker or multi-station stitching, as used in CNC boring or mass production environments, can take up to a full shift.
3. Data alignment and analysis (2–6 hours)
Raw scan data is aligned to the CAD reference, cleaned, and filtered. Engineers verify tolerances, extract profiles, and generate deviation maps. Materials like Inconel 625 or titanium Ti-6Al-4V may require temperature compensation or point-cloud smoothing due to surface reflectivity.
4. Report generation and validation (2–4 hours)
The inspection software compiles measurement results into a structured format, including 3D deviation plots, tolerance analyses, and GD&T summaries. Reports are finalized and reviewed under ISO 9001 or AS9100 protocols before release. This step ensures conformity for regulated sectors, including aerospace and aviation, medical devices, and industrial equipment.
Key variables affecting total time
Part size and complexity – More data points and features increase processing load.
Material reflectivity and surface treatment – Surfaces treated by anodizing or polishing demand tailored scan settings.
Tolerance level required – Tighter precision (±5 μm) requires slower scanning and denser point clouds.
Reporting standard – Aerospace PPAP, FAI, or custom OEM templates extend review duration.
In most cases, a medium-complexity component can transition from scanning to final certified inspection documentation within 8–24 hours, striking a balance between precision and throughput efficiency.
