How is the Accuracy of Industrial CT Scans Verified?

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.

ISO9001 vs ISO17025 vs AS9100 – Why It Matters When It Comes To Your Metrology Needs

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.

How accurate is a CT scan? – Computed Tomography and Metrology

Metrology Grade CT Scan

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.

Seeing your part through a different lens – Utilizing the Zeiss O-Inspect 863 for optical inspections down to a hairs width

Utilizing the Zeiss O-Inspect 863_1

In the past year 3D Engineering Solutions acquired a Zeiss O-Inspect 863. The unit is a state of the art optical / tactile inspection system that adds to our scope of accreditation, for ISO 17025, a capability to measure parts on a scale that we were unable to accomplish prior to having this equipment.

Color Mapping Technology for First Article Inspection

As part of our ISO 17025 quality inspection services at 3D Engineering Solutions, we now provide color mapping technology for first article inspection of cast parts, a service many other engineering firms still do not offer.  Color mapping provides qualitative illustrations that show the difference between a scanned object and its nominal design.  We provide different types of analysis for our customers, giving them both quantitative and qualitative data.  This saves time and money in the qualification process and makes it easier for our clients to get parts to their customers.

Leading Edge Scanning Technology Helps Improve Part Verification & Accuracy

We recently finished a project here at 3D Engineering that used scanning technology to verify the accuracy of plastic injection molded refrigerator parts.  In one sense, this is nothing unusual; we frequently using scanning to verify part accuracy.  Most companies, however, still use a fixed based Coordinate Measuring Machine (CMM) to conduct part verification.  CMM technology captures hundreds of data points, but scanning collects millions of data points, allowing us to gain much greater qualitative and quantitative information.  Because we have the equipment and the knowledge to implement scanning, we now use this leading metrology technology for most inspection projects, including First Article Inspections (FAIs) and Production Part Approval Processes (PPAPs).
