Abstract:
1. A method for determining the positional laydown accuracy of an automated lamination machine during fabrication of a single or multiple layered part, said method comprising: determining a position of a placement head of the lamination machine in a coordinate system; determining a location of a ply edge with respect to the placement head using a machine vision system; transforming, with a processing device, the location of the ply edge into the coordinate system, based on the placement head position; transforming the location of the ply edge from the coordinate system into a second coordinate system that is associated with the part being fabricated; comparing actual ply edge location in the second coordinate system to an expected ply edge location defined in the second coordinate system, the second coordinate system associated with the part being fabricated; and determining the laydown accuracy of the machine based on the comparison.
