A method and system may be provided for determining a set of parameters for preparing a skin for assembly to a substructure. The skin may be nondestructively inspected to gather a data set relating to the skin thickness. Sets of as-built thickness values for the skin and of deviations from a nominal map of the skin thickness may be calculated. A mating area for the skin and substructure and a set of one or more locations for fastener holes in the mating area may be determined. A set of parameters for the one or more fastener holes and a set of one or more fastener lengths may be generated using the deviations. A tool may cut the one or more fastener holes using the set of parameters and the skin and substructure may be fastened using fasteners selected according to the generated set of one or more fastener lengths. The system may be used with a numerically-controlled machine, a nondestructive inspection system, and may include a computer coupled to the nondestructive inspection system for calculating the parameters for preparing the holes and the lengths of the one or more fasteners.

Disclosed is a system for measuring and controlling the thickness of asphalt roofing materials during manufacturing. Light beams are used to generate a time of flight signal that is used to determine the thickness of the asphalt roofing layer. A controller generates a thickness control signal that controls a coater to modify parameters of the coater to produce the asphalt roofing layer with a desired thickness.

A method for operating a press, wherein a relationship between a detected component property (current value) of the final product (e.g. surface quality), the provided material property of the semi-finished product (e.g. sheet thickness), and the detected production parameter (e.g. pressing pressure) is determined, for example, by a self-learning algorithm, on the basis of precedingly determined differential values between target and current values of the component property. The algorithm is subsequently used for targeted selection of samples for quality monitoring.
