Industry: Digital Manufacturing, Digital Twin

INTRODUCTION

Temperature maps configuration (Temperature vs. time) for different laser applications. The smart closed loop temperature control is based on thermal camera measurements (it is also possible to integrate other sensors: pyrometer, thermocouples,…) the data measured by these devices is injected into digital platform and thus into a generic database.
The implementation uses AAS (Asset Administration Shell) technology for digitally representing the objects of the machine. The database serves as input into an analytics module that controls whether the laser process is right or wrong and has or not to be stopped and the decision is sent to the laser control module.

FEATURES/BENEFITS

  • Increased productivity, flexibility, and quality standards.
  • Zero-defects manufacturing (first time right)
  • Better energy efficiency reducing production.
  • Better process understanding and optimizing.

USE CASE

In conjunction with Gestamp, we produce components for the automotive sector that address today’s environmental requirements. To do so, we have used all of our knowledge to develop pioneering software that enables us to modify the manufacturing processes of automotive components and adapt them to more flexible, lighter and large scale materials.

Smart software that also enables us to take dynamic and independent control of the temperature in order to fulfil the safety specifications of the lightened parts with different geometries, whilst maintaining their quality and metallurgical properties.
We have also succeeded in lightening the weight of the vehicles, reducing the wear of components and increasing their durability whilst maintaining the highest levels of safety. It is a complete and innovative solution that shows our commitment to the planet, industry and society as a whole.
