Discussed in detail using BP neural network to establish the quantitative relationship model between the process parameters and components density on the laser direct rapid forming (LDRF) metal parts, in which input of single-pass sintering model is: laser power (P), scanning speed (V) and powder feeding rate (G), performance indicators to measure the width of the sintered layer (W) and height (H);input of multi-pass multi-sintering model is: P, V, G, scan spacing (D) and layer thick (ΔZ), the performance measure for the density of sintered parts, And neural network simulation results an...
