Computer-Aided Inspections (CAI) can be used for first article inspections, inspecting tools for accuracy or wear and monitoring manufacturing processes. Computer-aided inspection technology includes geometric algorithm software, non-contact 3D scanners, computing power and mass data storage. Computer-aided inspections have been used within the automotive industry at engine-building plants.

How’s Computer-Aided Inspection’s performed?

Your part or product is scanned to produce point cloud data. That data is converted to a clean mesh file that is then placed on top of the original computer-aided design data. A best fit function will be performed to make sure that the data is lined up correctly and spaced efficiently.

Then, the scanned data will be compared to the original computer-aided design data to determine the differences. Color deviation maps will show where the part surface is above or below the design surface. Computer-aided inspections introduces a faster and easier method to compare as-built parts with their 3D computer-aided design.

Overall, computer-aided inspection saves time and on money on first article inspections. You’ll spend less time collecting data and have more time to analyze.
