Different Digitizing Methods
Scan data collection methods:
San data can be collected using various methods and at various accuracies, depending on the application and use.
Laser scan
- High accuracy scan 0.0006"
- Ideal for scanning parts ranging from 1 inch to 24 inches.
- Ideal or inspection and dimension verification
- Fast scanning speed
Pros
- Limited work envelope, large parts are difficult to scan.
- Captures data on a line-of-site basis. Undercuts and deep holes are challenging to scan.
- Glossy, transparent, and reflective surfaces will not yield good data.
- Most of the time parts have to be coated with a thin coat of grey primer paint.
Cons
White Light Scan (VX)
Pros
- Good for scanning very large parts. 1 ft to 5 ft
- Scanner is portable and scan can be performed at customer's site.
- Quick scans
Cons
- Low accuracy .005 in
- Difficult to capture complex geometry
X-ray Scan
Pros
- High density data capture on very small parts
- Ideal for parts smaller than 1 in for metals and 2.3 inches or plastic.
- Captures all the internal details
- .0001 resolution
- May increases lead time on the job
CGI scans (Capture Geometry Inside)
Pros
- Captures internal detail with high accuracy.
- Ideal for parts ranging from 2 to 15 inches.
- Accuracy comparable to laser scan. 0.0006in
Cons
- Parts are destroyed due to physical sectioning.
Surface Profilometer
Pros
- Good for characterizing scratches, pattern, or very small variation on a surface.
- 1 um (micron) ( .0001 mm or .000004 in )
Cons
- Not ideal for large parts
