Method and apparatus for controlling stresses in a spray form process makes
use of one dimensional modeling in which characteristics of a geometrical point
are quantified by iterative detection, such as taking a surface temperature reading
using a pyrometer. This temperature information is used in a one dimensional simulation
to predict characteristics for a column from the point down through a spray-formed
article to an interface with a substrate. The modeling technique can used with
a plurality of geometrical points to model the whole article, and the one dimensional
simulation can be integrated with robotic spray-forming controls to minimize residual
stress in the spray-formed article.
