Abstract

This paper introduces a concept to integrate measurements data into feature-based 3D CAD models. The concept focuses on its application in the measurement of bifurcated sheet metal profiles. For that, an interface to read and import this data into the CAD system is developed. Since the measurement data is stored as a point cloud, further data processing (reverse engineering) is necessary to recreate the work piece shape in the CAD system. If the measured work piece model and the CAD model of the design piece are available, an automated comparison of the defined dimension takes place. The result is a notification in the CAD model indicating which dimension deviates from the target values. Use-cases are elaborated for integrating the concept in the product development process. To implement this concept, an experimental setup is built up consisting of a measurement system and 3D CAD system. The COPRA ProfileScan Desktop is used to measure the profile. Siemens NX 11 is the chosen CAD system. Based on this setup, the concept is validated on a manufactured profile.

Dieses Papier stellt ein Konzept zur Integration von Messdaten in funktionsorientierte 3D-CAD-Modelle vor. Das Konzept konzentriert sich auf seine Anwendung bei der Messung von gegabelten Blechprofilen. Dazu wird eine Schnittstelle zum Lesen und Importieren dieser Daten in das CAD-System entwickelt. Da die Messdaten als Punktwolke gespeichert sind, ist eine weitere Datenverarbeitung (Reverse Engineering) erforderlich, um die Werkstückform im CAD-System wiederherzustellen. Liegen das gemessene Werkstückmodell und das CAD-Modell des Konstruktionsteils vor, erfolgt ein automatisierter Vergleich der definierten Abmessung. Das Ergebnis ist eine Meldung im CAD-Modell, die angibt, welche Dimension von den Sollwerten abweicht. Es werden Use-Cases zur Integration des Konzepts in den Produktentwicklungsprozess erarbeitet. Um dieses Konzept umzusetzen, wird ein Versuchsaufbau bestehend aus einem Messsystem und einem 3D-CAD-System aufgebaut. Zur Messung des Profils wird der COPRA ProfileScan Desktop verwendet. Siemens NX 11 ist das gewählte CAD-System. Basierend auf diesem Aufbau wird das Konzept auf einem hergestellten Profil validiert.German
