Scan to CAD Alignment Methods

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.

Long Range Scan Alignment Using Spheres

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.

Basics of Metrology : Measurement Uncertainty and Accuracy of Equipment

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.

Engineering Support Services: Aligning Smooth/Large Objects

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.

Reduce FAI/PPAP time & cost by 80%: The New Inspection Paradigm

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.

Presentation to ASNT, January 27, 2015

The American Society For Nondestructive Testing (ASNT) is the leading technical society for nondestructive testing professionals. I am honored to have accepted an invitation to present to the Central Ohio section later this month.

The topic of the presentation is, “Precise Non-Destructive Inspection of Complex Parts and Assemblies with Inaccessible Internal Cavities“.

Date: January 27, 2015
Time: 5:30 pm – 7:30 pm
Cost: Free (food and light refreshments will be served)
If you plan to attend, please contact Jing Ma, Central Ohio Section Secretary, to make a reservation or for more information. All reservations are final on January 25.

A First in Industrial CT Scanning Services

We have been talking about our new industrial CT scanning services over the last few months, and now have great news to share. 3D Engineering Solutions is the first company in the world to receive an ISO 17025 certification for industrial CT scanning services. This means that internal and external elements of an assembly can be scanned and analyzed with intense precision, like no one else can.

What to Consider When Using Industrial CT Scanning

With 3D Engineering Solutions adding two new industrial CT scanning systems from Nikon Metrology, and the upcoming opening of an industrial CT scanning Center of Excellence (the first of its kind in the United States), I thought it would be a good idea to record my answer an important question about the technology:

When should I consider using industrial CT scanning vs. other scanning technologies for collecting 3D metrology and point cloud data?

Do you have any other questions or comments about industrial CT scanning or its uses? Please let me know. Feel free to contact me or call our offices at (513) 771-7710.
