ABSTRACT:
A method for determining the positional laydown accuracy of an automated lamination machine during fabrication of a multiple layered part is described. The method includes measuring 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, transforming the location of the ply edge into the coordinate system, based on the measured 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, and 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, to determine the laydown accuracy of the machine.
