Sneak Peek of Digital Twin at DMDII

On July 12, 2017, we will demonstrate integrated machining and measurement using digital twins. The video below shows a sneak peek. We were testing the DT1 (Digital Twin One) software product on a Siemens 840D SL and Hyundai Wia mill at the DMDII on June 16, 2017.

In this footage, the machine is air milling, and we use the twin to show what will be machined. The twin is reading live feedback from the Siemens control every 4ms, and showing the output using a web browser on the HMI.

In the upcoming demonstration, we will machine the part and measure it. The twin server will read results from a Rennishaw probe and use MTConnect to send them to a metrology server provided by Mitutoyo. The new demonstration builds upon the digital twin capabilities that we have already shown.

Digital Thread and Digital Twin

On October 5th, 2016, at the Future of Flight museum in Mukilteo, three audiences from OMAC, Boeing, and ISO TC184/SC4 digital manufacturing team saw a demonstration of standards-based digital thread and digital twins:

  • A standards based digital thread was used to update a machining “twin” model in real time
  • The machining model was measured using on-line software, and off-line using a CMM.
  • New automations are possible when machining is measured in real time. They showed feeds being made 15% more efficient by monitoring chip thickness.

Version 17 Software Released

April 20, 2017 — Version 17 of the STEP Tools development stack of libraries and tools is now available for use in STEP, IFC, and Digital Manufacturing solutions. The full stack includes the EXPRESS-level STEP and IFC libraries previously packaged as ST-Developer as well as our STEP-NC simulation and machining libraries, .NET and Node interfaces, an enhanced business-logic level APIs.

Our software stack has grown over the past twenty six years. At the heart of the software is the set of EXPRESS-based C++ programming libraries used within many commercial STEP and IFC CAD interfaces. Built on top of this are the newest simulation and high-level APIs along with .NET and Javascript client-server interfaces that are bringing Digital Manufacturing into production.
