ABSTRACT:
According to one embodiment of the invention, a method for controlling operational weld parameters of a welding-based deposition process includes generating a solid model representing a three-dimensional part on a computer, electronically slicing the solid model into a plurality of electronic two-dimensional layers, identifying a path of material deposition based on the electronic two-dimensional layers, the path comprising a plurality of deposition points, and determining a geometrical factor for each deposition point. The geometrical factor is defined by a ratio of an actual volume of material around each deposition point to a theoretical volume of material around each deposition point. The method further includes automatically adjusting, during material deposition for a respective deposition point, one or more parameters of the welding-based deposition process based on the geometrical factor for the respective deposition point.
