Layer based micro-machining—New approach for tool-path generation

This paper proposes a new tool-path generation approach for layer-based micro machining (“conventional”, laser or EDM milling). With this approach, the laser spot non-conformity or EDM tool wear is compensated for by varying the layer machining angle and start point while the material removal volumes are represented by a sequence of 2D slices. Tool-path generation is performed taking into account the specific requirements of 3D micro-machining. The capabilities of the developed CAM system have been verified experimentally.
