OPTIMIZATION OF PROCESS PARAMETERS IN DIRECT METAL DEPOSITION TECHNIQUE USING TAGUCHI METHOD

Direct Metal Deposition (DMD) process is an important component in many industrial operations. The DMD parameters are the most important factors affecting the quality, productivity and cost of metal depositin. This paper presents the influence of DMD parameters like Laser power, laser scan speed, powder mass flow rate on height deposition in DMD. A plan of experiments based on Taguchi technique has been used to acquire the data. An Orthogonal array, signal to noise (S/N) ratio and analysis of variance (ANOVA) are employed to investigate the DMD characteristics & optimize the height deposition. Finally the conformations tests have been carried out to compare the predicated values with the experimental values confirm its effectiveness in the analysis of penetration
