In the RMS-process, metal is deposited layer by layer at desired positions by melting a metal wire using a robotized fibre laser welding equipment. The process consists of the following steps:
1. CAD-drawing which defines the desired metal build-up
2. Computation of component slices of the same thickness as one layer
3. Preparation of the robot paths and process parameters
4. Check access by robot off-line programming
5. Build up the component using sensors and feedback control
6. The resulting component
7. Validate the geometry
The project objective was to automate the entire process, from CAD-drawing to validated component.
Started as a pre-study in 2005.
Ended 2009, March 31.
