While laser placement produced a giant step forward in layup efficiencies in the early 1990s (documented in HPC September/October 1994, p. The process had to be repeated for each successive ply. Each template had to be lifted by two people, and then the three had to be bolted together, pinned into the tool, scribed for the outline and then removed before the ply could be placed. Previously, the customer had layed up its 28-ft long helicopter rotor blades in the traditional time-consuming process, using three 9-ft long fiberglass templates for each composite ply. "The customer documented that lasers eliminated 80 percent of the fabrication time," says Scott Blake, president of Assembly Guidance Systems (Chelmsford, Mass., U.S.A.), of one of his earliest customers' experience with his company's laser placement equipment. When laser projection systems first replaced physical templates in aerospace composite layup in the 1990s, the result was nothing short of revolutionary.

The system can align and project onto two or more independent tools simultaneously. All laser controllers today can control multiple projectors directed at single tool, but Assembly Guidance Systems has enhanced its controller productivity by supporting multiple coordinate systems.
