Fab-CheckerTM PVS-48

The Fab-CheckerTM is a state-of-the-art high resolution, large format scanning device, specifically designed to evaluate fabricated 2-dimensional sheet metal parts for accuracy and compliance with specifications. Parts are scanned using a high-resolution line scan CCD camera, mounted on a precision x-y table. The scanned part is compared with the original CAD drawing (in .DXF format). Dimensions not within the specified tolerances are identified; these are clearly displayed on the monitor as a different color from the remainder of the drawing, and data is generated for SPC evaluation. Total processing time for a 48" x 48" part scanned at a resolution of +/- .002" is 240 seconds, significantly less than the 30-45 minutes it would take to do this manually (smaller parts can be scanned and processed much more rapidly). Using the Fab-Checker, first part inspections are performed quickly, easily, and accurately, with excellent documentation. This decreases idle time on the NC punch press/laser/plasma/water jet, and correspondingly increases factory throughput.

The Fab-Checker also is ideal for reverse engineering of sheet metal flat parts, whereby a CAD drawing is quickly and accurately generated from a sample part where no CAD drawing exists. This can save hours from the process of manually measuring the part to create a CAD drawing. The Fab-Checker generated .DXF file can then be exported into a CAD package that supports drawing interchange format (.DXF) files.

The Fab-Checker is extremely cost-effective, saving the fabrication shop through:

Reduced idle time of NC punch/laser/plasma/water jet cutting machines while waiting for manual first part inspection

Improved accuracy of first part inspection leads to decreased scrap and reduced requirements for rework

Increased factory productivity

In fact, in a typical fabrication shop performing 10 first part inspections per day, the resultant time savings from using the Fab-Checker translates to a time to payback of the total investment of <10 months!
