3D Engineering Solutions’ state of the art, temperature controlled, and ISO17025 accredited metrology lab offers certified digital radiography services. Our metrology lab and 30,000 sq. ft. of warehouse space can accommodate customer’s needs; from single part projects all the way up to production part projects for tens of thousands of parts. We have bar code logging capabilities for projects requiring full traceability and 100% data accountability.
3D Engineering Solutions has recently acquired a Creaform GO!Scan 3D. This gives us the opportunity to offer yet another option when it comes to data collection for our customers. With this scanner, large parts can be scanned significantly faster. This is helpful in many situations.
There are multiple ways to align scan data to a CAD model. The main three methods used at 3D Engineering Solutions are best-fit, datum reference frame, and feature based.
When to use Spheres with Long Range Scanning
At 3D Engineering, we sometimes have projects that involve conducting long range scans of large buildings. Scanning these buildings is more complicated than just placing the scanner in the center of a room and being finished after one scan (unless your building is a single room). You have to consider the complications that come with hallways and corners, which must be worked around. Multiple scans must be taken to accurately align each aspect of the building to each other. While this can be done using a few different methods, one of the most dependable procedures uses white spheres.
If you’ve ever contracted 3D Engineering Solutions to perform a part inspection for you then you’ve more than likely received a certified inspection report. There are a lot of items on this report, but aside from the results you are looking for, one of the more important items will be the stated measurement uncertainty for the equipment we used.
I am here today to share how 3D Engineering Solutions is a leader in CT scanning engineering. I’ll explain how we are the only company to have a piece of CT equipment to our ISO 17025 scope. This new piece of equipment allows us to perform more accurate scans.
Aligning Multiple Scans of a Single Object
Something people may not think about is the processes used to align multiple scans of a single object, as many parts require more than one scan to fully cover the object. Sometimes the part may be too large for the equipment to cover from one spot, or a part may need to be flipped over to scan the bottom. When this happens, two or more separate scans must be conducted by scanning the part in one position, then moving it and scanning again. Some parts have enough unique features to use for alignment, by signaling the software to use those features as the basis for aligning.
Traditional FAI & PPAP
Traditionally FAI (First Article Inspection) and PPAP (Production Part Approval Process) inspections include a complete look at all the print dimensions. A typical dimension may take 10-minutes to fully program, collect the data and report using traditional methods. Because prints can easily have between 150 to 1,000 dimensions, this becomes a significant time and resource constraint for many projects.
When it comes to engineering services, we know there are many options to consider. To better explain how our services compare to the competition, we created a video that answers the question:
