Abstract

The single track is the basis of the multi-track overlapping and multi-layer molding in the accumulative manufacturing, and its quality determines the quality of the parts after their being manufactured. The single track experiment on Ti-6Al-4V powders has used Matlab software to fit the experimental data so as to establish the mathematical model. As a result, the experiment has revealed the functional relationships among the width, layer thickness, and power/speed of Ti-6Al-4V selective laser melting single track; and its relationships between its width and layer thickness, width and power/speed, with the period T1=0.0753,T2=0.0542 respectively, satisfy the Fourier series.
