Metris Laser Radar Automates Inspection
Brighton, MI — Metris has released Laser Radar Driver 5.1 software to set new precision standards for automated, non-contact inspection of holes in large measuring volumes. Depending on hole diameter, the system allows for accuracy and repeatability levels up to 30 times higher than before. Laser Radar's innovative laser technology supports both automatic freeform surface measurement and feature detection/inspection.
Stricter quality requirements in aerospace industries increase the pressure on manufacturers and suppliers to further tighten feature tolerances. Correct positioning of features, such as riveting holes, is crucial in aircraft component assembly. With the new software release, the company has optimized the capability of the system to inspect hole feature position and diameter in large-scale applications.
To increase operation flexibility, Laser Radar provides both manual and automatic modes for the inspection of hole features. In automatic mode, the operator selects the holes to be inspected on CAD, and the Laser Radar automatically moves from one hole to another to measure the holes at high speed. Compared to the traditional laser tracker inspection, which requires an operator to manually position a SMR reflector in each hole, Laser Radar hole inspection routines are entirely automatic. According to the company, the time savings are huge, in particular when measuring large composite parts with hundreds of riveting holes.
The software algorithm optimization increases the accuracy and speed of hole feature measurement by implementing an optimized data collection strategy, more accurate filtering technology and better feature fitting. Using a 0 to 45° laser incident angle within a 8m (26 ft.) perimeter, Laser Radar realizes average mean accuracy between 10µm (0.0004-in.) for holes with a diameter of 3.2mm (0.126-in.). The new hole inspection algorithm proves its robustness by accurately capturing hole position and diameter up to a distance of 24m (78 ft.). Customer benchmarks show that the same inspection performance gains can be achieved for sharp and chamfered holes drilled in aluminum, steel and composite material.
