Seeing the Unseen - Sensors With Sophisticated Data Models Enable Higher Manufacturing Quality
Presenter: Markus Kogel-Hollacher,
Precitec GmbH & Co. KG,
Germany
Normally, the phrase "seeing the unseen" is used when sensors/cameras are applied for monitoring purposes that operate in a different spectral range than the human eye.In this contribution to CLEO 2023, we will interpret this formulation somewhat differently. It is already known that there are commercial sensor systems for monitoring or controlling laser processes. Most of them are based on camera or photodiode technology. It is also known that the introduction of OCT in laser material processing has significantly increased the safety of both defect detection and process control. The focus of this presentation, however, relates to the use of artificial intelligence algorithms to "See New Things". We will discuss how classified, physical properties can be derived from already reliable process information - "seeing the unseen", so to speak Instead of defining complex rules for algorithms, the use of DataScience and Machine Learning methods reveals hidden structures in noisy unstructured data and make it possible to find the relationships of the data to physical measurements.Authors: Joachim Schwarz, Precitec GmbH & Co. KG / Markus Kogel-Hollacher, Precitec GmbH & Co. KG
