Digital Inspection

Digital or Computer Aided Inspection (CAI)

CAI is a paperless inspection method that compares a solid CAD models to the 3-D scanned part’s point-cloud. It may also be referred to as first article inspection. The advantage is that 3-D scanning can generate hundreds of thousands or millions of points, far more than the most sophisticated CMM touch probes. This process offers a quick and inexpensive way to inspect complex parts

The client’s solid CAD model can be registered to the point-cloud in one or two ways; at critical datum’s or using a best-fit algorithm. Color maps are then created showing the differences. Cross-sectional views showing exact dimensional differences assist in modifying either the CAD file or the tooling.
