Cross Sectional Scanning

There are a lot of ways to inspect parts:  Traditional CMM, Laser Scanning, and several optical methods.  The problem with all of these is that they only measure a small number of critical locations, they may lack the accuracy you need, and none of them allow you to measure internal features.

Very Accurate Scanning
that Captures Internal Features

Cross Sectional Scanning (CSS) was developed by CGI, which actually stands for Capture Geometry Internally, to address these very shortcomings.  The CSS process actually machines off very thin layers of your plastic parts, imbedded in a rigid urethane, and records the outline of each layer using a highly accurate optical scanner.  This approach produces very accurate point cloud data of all of the parts geometry, not just the outside.

Once we have the accurate data, PADT can conduct a variety of tasks:

  • Convert to an STL file for use by the customer
  • Conduct full part inspections against a CAD model or critical dimensions
  • Carry out a statistical assessment of part feature size based upon inspecting multiple samplings of the part
  • Convert the data into an accurate solid model in a variety of formats

This process is ideal for first article inspection, critical dimension checks, and reverse engineering for most plastic parts.  It is especially useful for parts with small, complex, and internal features.  PADT added this service to our offerings simply because we could not find a better way to meet the requests of our prototyping and injection molding customers who needed accurate measurements of their parts.  Our extensive manufacturing and quality experience is utilized for customers who require rigorous inspections with documentation.
