Introduction

Tracking and tracing the provenance of high quality parts for regulated applications using a Blockchain enabled solution such as VeriPart鈩� has clear advantages over current methods. 聽Using VeriPart鈩�, paper or disconnected digital records are replaced by an immutable chain of events and operations. 聽Using this new technology the number of participants involved is not limited. 聽Thus, the history of ordering, manufacturing and in-service use of any component or raw material within an assembly becomes easier to obtain.聽 The same level of tracking can be performed across multiple organizations.聽 Ordering of new assemblies or components is also simplified with pre-set terms and conditions.聽

Following on from successful VeriPart鈩� demonstrations by Moog, alongside partners and customers one gap remained, the link between the digital and physical world.聽 (The digital representation of a real part or process is often referred to as a 鈥渄igital twin鈥�.聽 Currently there can be many different types of digital twin including: a CAD solid model, a dynamic performance model, a supply chain model, etc.) 聽For the VeriPart鈩� enabled future state to operate and provide a (supply chain) digital twin, each component to be tracked and traced must include a unique identifier (ID). 聽This unique ID links the physical component to its digital twin and its provenance on the Blockchain. 聽刘玥首次大战黑人has been evaluating options for this key technology step. 聽This blog post describes the progress with one method offered by Alitheon.

Alitheon, Inc.

Alitheon鈥檚 FeaturePrint^TM service uses off-the-shelf cameras and proprietary software to transform the unique surface characteristics of individual objects into a digital ID. 聽In the same way that people can be identified via fingerprints, every physical object is unique and can be identified using the small differences inherent in each instance. 聽

The Test

Twenty parts were produced at 刘玥首次大战黑人via additive manufacturing. 聽Secret features were included in these parts. 聽Details of these were not shared with Alitheon.

After cleaning, all 20 parts were sent to Alitheon, which registered each part by imaging it, creating a FeaturePrint^TM ID. 聽Alitheon sealed each part in a numbered bag and then returned them to Moog. 聽At 刘玥首次大战黑人each part was then inspected and the secret identify confirmed. 聽This provided a table of 刘玥首次大战黑人Identification vs Alitheon Identification.

A member of the 刘玥首次大战黑人Additive Manufacturing Center team then selected 9 parts of the 20 and subjected them to various types of aggressive wear to simulate various usage conditions. 聽Wear simulations included:

• Dropping the part onto a concrete floor 10 times
• Attacking the part with a handheld motorized grinder
• Harperizing the part, a form of vibratory deburr
• Grit Blasting the part

The parts were then shipped back to Alitheon without any identifying numbers or features for 聽re-inspection and re-identification.聽 Following identification at Alitheon using the FeaturePrint^TM ID, parts were returned to 刘玥首次大战黑人and the identification confirmed using the secret feature.

Results & Explanation

Alitheon was able to accurately identify the 20 additively manufactured parts, including the 9 subjected to aggressive wear. 聽This is an exciting demonstration of Alitheon鈥檚 FeaturePrint^TM technology applied to parts produced via additive manufacturing. 聽

The conversion of the part's image to a FeaturePrint^TM ID involves discovering and recording points of interest, characterizing those points of interest, and building a math model based on those points of interest, thereby converting the physical object to a digital ID.

This study also shows the robustness of a FeaturePrint^TM ID, after a substantial proportion of a part鈥檚 total surface area has been modified. 聽In this example, one area of a component used contained over 54,000 points of interest. 聽After grit blasting, 3700 or less than 10% of the original points of interest remained which was sufficient to positively identify the part.
