Laser Aided Manufacturing Process (LAMP)


"The Laser Aided Manufacturing Processes (LAMP) developed at the University of Missouri--Rolla are used to fabricate three dimensional metal and ceramic parts. The part material is supplied in the form of powder, and the laser is used to melt the powder onto a substrate. Layer-by-layer addition is done to build fully functional metal parts directly from a CAD model. The laser scans the substrate and deposits the part according to the slices, and then the 5-axis machine process finishes the part to near net shape. This thesis describes the experimental analysis done for modeling and control purposes of the Laser Aided Deposition Process. A machine vision sensor and an infrared temperature sensor have been used to monitor the melt pool dimensions and peak temperature during deposition. A laser displacement sensor was used to determine the layer height. Other process parameters like powder flow rate measurement, CNC table velocity and laser power were studied using open loop tests. These input parameters were varied, and their influence on process output parameters like melt pool temperature and melt pool dimension were studied. Results obtained through experimental analysis show a reasonable agreement with simulation results"--Abstract, page iii.
