Virtual Manufacturing Processes

The group has a clear research focus on modelling and simulations of machining processes. This is an area that becomes more important since the development time and costs for designing new products and processes needs to decrease to be competitive on a global market. Many companies introduce new strategies into their organization to handle this issue. Modeling and simulation allow for this if they are reliable and predictive. Since the computers are becoming more powerful the models can be more advanced to mimic the real process that takes place.

The group both use and develop models for the traditional processes such as turning, milling, drilling etc. In most cases we utilize the finite-element method (FEM) in our simulation models when we study the cutting processes. By means of the FEM we can determine e.g. cutting data in order to minimize wear, chose cutting tool without conducting a lot of experiments and tests, thus minimizing the number of tests.

The group’s main focus is on developing accurate simulation models of machining processes for real industrial casas. The puts demands on the knowledge of the mechanics and physics that governs the cutting processes. Machining is a very complex coupled thermo-mechanical process with extremely high strains, strain-rates at high temperatures. Often, vibrations are introduced and this might influence the process. All this phenomena makes the work extremely challenging and a lot of research is carried out in this field around the world.
