Due to physical material fluctuations and process uncertainties, it is statistically impossible to produce components with identical metallurgical and geometrical properties. Although all components have to meet the same requirements, not all components can withstand these loads due to their individual properties. However, if it were possible to create a digital twin of the components and make this individual information publicly available, suppliers could adapt their downstream steps to specific components and increase end customers’ confidence in these components, assemblies or products.

The goal of this PoC is to extract production data of fineblanked components from the machine control in real time, store them encrypted in the tangle and retrieve them via a web-based frontend. The PoC is limited to selected data, such as the blanking force, the press stroke or the material name.

Focus of this article and sneak peek of the results

This article focuses on data acquisition as the first and most crucial step. But additionally some real test transactions are already stored in the official testnet. The following video shows that for each part produced a data set is queued firstly and then stored in the tangle.
