Structural Casings Inspection
A single optical measurement setup for multiple structural casings
Whether taking flight or heading a launch carrier for spaceships, structural casings in aero engines carry out multiple jobs. While they’re known for giving structure and rigidity to the engine under thrust, they also help direct air with guide vanes, protect from fire surges, and contain fragments in case of failures during flight. These highly intricate structures are situated throughout the engine from the compressor to the turbine, all the way to the exhaust. In an industry that demands high-level accuracy and quality assurance in the shortest time possible, these kinds of components need an all-in-one solution to inspect every type produced.
Constant pursuit of process optimization
Striving for process optimization aero customers request for one system that measures everything from the casting, to the machined parts, and even complex fabrications. Using the ATOS ScanBox allows for rapid measurement of parts with high-resolution sensors equipped with a large field of view and customizable measurement options. These systems certifiable by NADCAP or certain ISO standards can even upgrade your existing operations by simplifying inspection processes at a faster rate and eliminating unnecessary steps and manpower. The ATOS ScanBox combines the best of automation and integration of powerful blue light technology to create a single setup, making the most out of your measurement room.
ATOS ScanBox
ATOS ScanBoxes provide a range of automated solutions due to the diversity of manufactured parts, so each system fulfils different needs. The ATOS ScanBox range is standard and scaled in sizes to meet your part size and throughput needs; from the smaller ATOS ScanBox 5108 for part sizes up to 800mm (ideal for small core engines, e.g. helicopters), to the ATOS ScanBox Series 6 for large, civil engines that allow single-side options and dual working areas—like the ATOS ScanBox 6235.
Casing
Casings and bearing structures typically start life as large castings with thousands of inspection requirements, often taking several hours using conventional tactile methods. It’s no surprise; the parts have thousands of features with complex geometries that require accuracy and precision. CMMs face the challenge of measuring freeform profile surfaces. This leaves aerospace manufacturers searching for a way to measure these large, complex structures all while meeting the industry’s exacting demands and fulfilling order backlogs.
Machining
In machining within aerospace, as in many other industries, tolerances are tight, scrap is kept to a minimum, and creating a repeatable process striving for continuous optimization in the production process is the goal for any manufacturer. Adding in complex designs for casings and the need for increased throughput present manufacturers with even more of a challenge: The more time it takes to machine each component, the more productivity and money is lost. To meet market demands optical metrology, or a combination of systems, will drive efficiency and throughput whilst producing high accuracy and precision.
Fabrication
One of the final stages of producing aerospace casings is through complex fabrication of machined components. In order to maximize an aircraft’s safety and performance, the fabrication process must be executed with extreme precision and accuracy every time. Because of the variety and intricacy of welds due to their form and position 3D data as given through optical metrology is a strong complement to other techniques to ensure joints are accurately manufactured and the process is repeatable and reliable. Manufacturers have struggled to find a 3D scanner that acts as an all-in-one solution to accurately scan multiple components from every angle, quickly and efficiently, until now.
