gemineers GmbH is a deep-tech start-up from Aachen. We develop software for the generation of Digital Twins in manufacturing to help production companies to manufacture faster and more cost-efficiently while increasing quality at the same time. The gemineers technology consists of three core elements: the machine and sensor data acquisition, the fully automated Digital Twinning and the user-friendly Web Dashboard. We use already existing machine data from the control system and process it based on our developed algorithms. The result is the Digital Twin of the manufactured part, which includes all relevant process data and enables an accuracy assessment from the very first part. The significant benefit of our software platform is the reduction of downstream measurement efforts in quality assurance by 80 % as well as a data-based optimization of the machining process by up to 30 %.
