Rapid inspection of aircraft parts

Marshall Aerospace (Cambridge, UK), an independent aerospace contractor, has done away with the time-consuming process of inspecting metal sheet components visually using foil lofts. In its place, the company is using the latest InspecVision Planar machine to be installed in the UK. Manufactured in Northern Ireland and supplied through UK agent, Press & Shear, the machine checks the profile and hole positions in sheet aluminium components to within ± 25 microns. Other 2D parts made from titanium, steel and plastic are similarly inspected.

    The need to find a more accurate way to check the 22 to 10 gauge (0.7 to 3.0 mm thick) components after they have been routed and drilled is being driven by increasing use in aircraft manufacture of predeterminate assemblies. They require components whose machined features are so precise that they fit together perfectly, without having to use jigs on the factory floor and ream out pilot holes. Advantages include avoiding the expense and lead-time of producing jigs, faster assembly and less risk of damage, especially if the operator is working in a confined space.
