Additive processes offer the possibility to produce complex geometries that are not possible to manufacture with traditional methods such as turning, milling or electrical discharge machining. Due to the layered structure of the material during the production process, the process time in the Fused Deposition Modeling (FDM) or Fused Layer Manufacturing (FLM) process is primarily dependent on the layer thickness. However, a large layer thickness induces deviations from the ideal shape of the component and features such as bores or fits. In a new approach, the additive process time will be reduced by applying excess material with a large layer thickness close to the desired contour. In a subsequent machining step, the excess material is removed, and the target contour is produced. This paper presents the first stage of this approach in which the alignment of an additively manufactured component within the working area of a milling machine is estimated based on CAD-Model and optical methods. |
