Hexagon’s Manufacturing Intelligence division has launched its scanner for automated inspection: the APODIUS Absolute Camera AAC, a camera-based sensor designed for the fine analysis of large numbers of small repetitive features such as the drill-hole formations often found in large aerospace components. The sensor is specifically intended for integration within an automated robotic inspection system controlled by a Leica Absolute Tracker AT960, and can also be integrated directly within a production machine.
The AAC offers feature analysis at a finer level of detail than other non-contact measurement solutions. Accuracy is to within just 10 microns for diameter measurements, even on holes with sub-millimetre diameters – alternative non-contact measurement options available for automated integration typical struggle with holes less than 18 millimetres in diameter. And with a measurement speed of 10 Hertz, the AAC can keep up with robot movement of 100 millimetres per second, allowing it to cover a square-metre area densely populated with small features in less than five minutes.
“We’ve seen many requests from aerospace users for a solution like this,” said Jonathan Roberz, Managing Director of APODIUS at Hexagon. “Small holes can be extremely challenging to measure quickly and accurately – some customers are still using pin gauges because of a lack of better solutions, while others have to move their part onto a nearby CMM and give up many of the productivity benefits of an otherwise automated system. This new sensor offers the opportunity to finally remove such manual processes from otherwise modern automated inspection by finally delivering a system that has the accuracy these applications require in an fully automatable form.”
Within a Laser Tracker Automated Solution, the AAC can become a key part of a complete automated inspection system. It is fully compatible with a tool changer system, allowing it to be used alongside a dynamic surface scanner such as the Leica T-Scan 5 to provide automated inspection of every aspect of large components with no compromising on feature accuracy.
