Abstract:
The complex nature of an LMD process demands advanced control mechanisms in order to compensate for the deviations that occur in the growth direction of the material. Consequently, every layer must be scanned to measure the 3D profile as layers are deposited, either by complicated in-situ measurement techniques or by performing intra-layer measurements after each layer deposition. Additionally, the digitization of the process allows the extraction and logging of relevant data and available process control and state variables for an ex-post analysis of the manufactured object. The quality of the extracted data directly affects the quality of the process itself, and typically high-end surface profilers are used, resulting in costly solutions. This work proposes an LMD process control solution that applies sensor fusion techniques to extract and integrate data from several cost-effective sensors. As a result, data-rich layer information is generated by combining process metadata and measured layer profiles using.
