Economies of scale heavily influence capital expenditure solutions. The automation and machine tool suppliers are forever working toward improved value. Case in point, the flex-track style systems gained momentum after integration on the Boeing 787 and Hawker 4000. Although they are considerably lighter than a monument style mounted automated drill type system, they still need some substantive level of a configuration change to be used on a different model or aero-structural assembly. Higher aircraft assembly build rates would allow the assembly section to move to the monument style automation fixture, or perhaps a fuselage joint type station that utilizes a flex track and alignment type system. Fast forward to today. Imagine all of the slower rate production legacy-type aircraft as listed above, many of which still have valid design basis in the '50s and '60s that don't allow the economy for monument-type assembly. Today, many of these are even being built manually, in many ways not far removed from the production methods during the era when they were conceived. Drill fixtures for hole locations with hand drills, or even power feed drills, are still prevalent in this market area, again, due to lack of scale and monument-type of automation solutions. We have several conceptions that are now coming to fruition to this end of the market, which not only allows automation with slower build rates but also the flexibility to easily navigate around existing major assembly fixtures. Imagine not having to take the product to the robotic "cell" but having an automated solution go to the product to work. This not only minimizes the need to perform expensive modifications to the tool string but also allows flexibility of the solution to drill several different assemblies at their current position on the floor. Moreover, Wilder Solutions' new technological innovations on robotic end arm effectors allow Congex type camera systems to identify hole placements for pilot holes placed on skins in 2-D from the '50s and 60's legacy designs. Aerospace structure manufacturing companies, like Vertex Aerospace headquartered in Madison, Mississippi, have recently helped develop and employ this type of solution. The agile manufacturing robot is designed to drill to a coordinate system that it picks up from existing tooling frames. Using the Congex camera system adds a layer of precision to identify pilot holes and drill them in one shot. Twenty-first-century leading-edge solutions for legacy airframe designs, such as this, bring economies and quality to a much broader market. I have been known to entertain and engage the engineers and professionals I work with by stating, "One day we will feed a print into a computer, and a machine will build the plane per the drawing." We are seemingly not that far off. Economies of scale heavily influence capital expenditure solutions
