Cover Story


John DworschakLaser projection uses CAD data sets that are commonly used in composite fabrication. The data is transformed into a laser projection and integrated with design/build instructions, showing workers how to perform a task at hand.

"A laser light projects an image onto the surface of the structure being worked with," DeGrange said. "The image might be a map of where to install parts, instructions on how to perform assembly, or an outline of part locations or fastener patterns."

Laser projection error-proofs the manufacturing processes, gets engineering and assembly instructions directly to point of use on the shop floor and improves quality. By projecting a quality control image onto the machined part—such as a boundary box inside which fasteners should be installed—quality assurance personnel and workers can see errors immediately.

Laser projection is being used on a number of Integrated Defense Systems programs in St. Louis and Wichita, Kan., including the C-17 and F-15 programs, and is beginning to transition to Commercial Airplanes.
