Process virtualization in manufacturing engineering provides valuable tools for engineers as they gain important insights into their processes long before the first tool is actually built.
It is a challenging task to model the processes appropriately. Classical mesh-based methods, such as Finite Element Methods (FEM), are very suitable to simulate structural mechanical properties of the workpiece; but they require high efforts for 3D meshing and coupling – if it is even possible – to model dynamical manufacturing processes. This is relevant, for example, when large deformations or cooling fluids are involved.
Advantages of MESHFREE:
- The moving point cloud approach is naturally suited to the dynamical simulation of manufacturing processes. Large changes in topology are manageable without the need for remeshing as in FEM methods.
- For a 3D simulation, MESHFREE only requires 2D surface meshes of the geometry. These are already available within widely used CAD tools at no extra effort.
- The scripting language enables easy incorporation of user-defined damage models.
