Industrial CT scanning continues to gain popularity for use in measurements. The real question to be asked is: Is the data extracted from CT scans accurate? Since its inception, CT scanning has been used to visualize internal structures from people to industrial items. It is unparalleled in its ability to see those things that are hidden inside an assembly. It is also important for measuring the effects of an assembly in its assembled state. Using CT data to provide accurate measurements has always been around but there was no universally agreed upon ways to ensure the validity of the measurements.
Every day, we in industry find ourselves in need of verifying the parts we have designed and built. Part of this verification comes in the forms of physical testing, as well as measurement and analysis. Whether you are looking at a prototype component or have a need to create an inspection plan for a production component, you will need someone who is proven capable in the science of measurement, otherwise known as the field of metrology. A simple Google search will reveal that there seems to be no lack of companies offering the services of metrology.
Since shortly after X-Rays were discovered in 1895 they have been widely used in many diverse applications. The medical field was an early adopter of this technology, using X-Rays throughout the world within the first year. As it developed in medicine other uses emerged on the industrial side.
With the advent of new ways of creating medical implants that promote bone ingrowth, an updated method of evaluating their effectiveness should be employed. 3D Printed Additive manufacturing and other creative manufacturing techniques have been developed to create porous structures that promote bone ingrowth. Traditionally, the effectiveness of these structures is tested by taking 2D cross sections of harvested implants and applying calculations to define pore size and interconnectivity. In this way, researchers can test and compare the Osteoconduction ability of the new structure.
When doing a dimensional inspection of a machine part, the print often has callouts for position that use three datum, most often datums A, B and C. This ABC datum structure is the datum reference frame to which geometric dimensions and tolerances of the part are defined.
3D Engineering Solutions (3DES), North Americas’ most Advanced & Proven Center of Excellence For Metrology & Engineering Services is pleased to announce their ongoing strategic partnership with Nikon Metrology, Inc (NMI) of Brighton, Michigan. 3DES recently purchased two additional advanced industrial computed tomography (CT) systems from NMI. These systems use X-rays to penetrate components and assemblies to retrieve all surface and internal details.
Recently, 3D Engineering Solutions was asked if we could detect porosity of a 0.2mm in a customer casting.
Finding your 0.2mm porosity should not be an issue.
We use Perkin-Elmer 16”x16” Panel detectors with a 0.200mm pixel pitch. That means that for each of the thousands of x-rays taken of your casting, the individual pixel size is 0.2mm x 0.2mm. So basically, the panel will see right at a 0.2mm defect. Beyond this, two other factors work in our favor: magnification and Sub-Voxel Resolution.
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.
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:
What differentiates 3D Engineering Solutions from scanning bureaus?
