Geometry Assurance & Robust Design

Core competence

The core competence within this group is within assembly modelling and analysis, robust locating system design, variation simulation, visualization, tolerance optimization, inspection preparation and use of inspection data for product and process control.

The research team has over the last decade produced a number of scientific results that have been transferred into commercial software products. Today, these results are being used in daily operation by a large number of engineers within 20-25 international companies


Research group leader: Professor Rikard Söderberg, Department of Industrial and Materials Science, Chalmers University of Technology.

The group currently consists of​ 1 chair professor, 1 adjunct professor, 6 additional senior researchers and 9 PhD students.

Industrial and scientific challenges

  1. Accuracy in simulation and visualization: High quality decisions, based on digital models and representations require:
    - better simulation models with higher accuracy and better representation of reality
    - better quality in input data for simulation models
    - better ways to present and use simulation results.
  2. Transferring simulation results into new product and process knowledge: Consistent use of simulation in different stages of the geometry assurance loop generates new knowledge and better understanding of specific product and production system behaviour, interaction and error propagation and perception and interpretation of digital models and visual quality.
  3. Design rules and working procedures based on new knowledge: New knowledge of specific system behaviour, perception and visual quality are used to establish rules and decision support for robust geometry design and guidelines and working procedures for use of simulation and visualization.
