Die Kernkompetenzen liegen in der Entwicklung von CAx Softwarelösungen für die Planung von abtragenden, spanenden und additiven Fertigungsverfahren. Um die häufig benötigten elektronischen Schnittstellen zu Fertigungsmaschinen nutzen zu können, legt AixPath Microcontrollerschaltungen aus und fertigt diese selbst.[/vc_column_text][plumber_headline bottom_lines="no" align="align-left"]Worum geht es? [/plumber_headline][vc_column_text el_class="justify"]Aixpath hat ein roboterbasiertes FDM-Drucksystem entwickelt und sehr erfolgreich auf der Leitmesse für 3D-Druck »formnext 2022« ausgestellt. Die aktuelle Anlage soll nun weiter entwickelt werden. Ziel ist eine höhere Flexibilität und Modularität. Das Praktikum sollte mindestens 18 Wochen umfassen (Praxissemester).[/vc_column_text][plumber_headline bottom_lines="no" align="align-left"]Deine Aufgaben [/plumber_headline][vc_column_text]

Readily available robotic systems are not yet accurate enough. They are not optimized for laser material processing. At the Digital Photonic Production group at the Chair for Laser Technology together with Aixpath GmbH, we are building prototypical novel kinematic systems for laser material processing, developing custom algorithmic solutions and process specific sensor concepts.[/vc_column_text][plumber_headline bottom_lines="no" align="align-left"]Scope of the Thesis [/plumber_headline][vc_column_text]Laser galvanometer scanner offer highly dynamic manipulation of laser spot position, which we want to use to compensate robot inaccuracies during motion. To accurately do so, scanner need to be regularly calibrated due to our combination with a six-axis robot and resulting position changes. Scope of the available thesis is the analysis and experimental testing of state-of-the-art laser scanner calibration patterns and the use of different imaging systems. Goal is to analyze influence of these parameters on the calibration result and enable system-integrated calibration. Tasks include:

1. Literature review on laser scanner calibration methods.
2. Programming of the laser scanner motion and image processing.
3. Experimental testing and comparison of different calibration patterns.
