3D Optical Coordinate Measuring System
Atech never ceases to pursue high-level technology for high quality assurance. Atech is the only Asian shipyard to borrow non-destructive testing technology from the aerospace industry to ensure final product quality. Atech incorporates three aerospace-level NDT Inspection Technologies to ensure quality assurance: Ultrasonic Inspection, Infrared Thermography and Laser Shearography.
Ultrasonic Inspection works by monitoring the sound waves propagating inside the composite material.
Infrared Thermography uses radiation waves to detect inner defects. A high-resolution camera can detect 0.025℃ (0.045℉) temperatures difference.
Laser Shearography is more advanced aerospace-level NDT inspection technology. It uses Laser light to provide information about the quality of different materials in strain measurement.
Every FRP component is created in a mold. Therefore the dimensional accuracy of the plug and the female molds is particularly important. Thus, Atech applies the aerospace-grade Optical 3D Coordinate Measuring System with a high-end 3D MaxSHOT optical scanning machine and computer-aided detection to precisely measure the dimensions of the plug and female molds.
The measuring principle of the Optical 3D Coordinate Measuring System is to photograph the surface of the mold via an optical lens probe, and then capture measured data from the beams’ reflections off the photosensitive sticker attached to the mold’s surface. After calculating and analyzing the measured data via software, the 3D digital information can be collected, and the profile differences between mold drawings and produced mold can be detected through computer data analysis. This method is also known as Computer-Aided Verification (CAV). Boeing, for example, utilizes the same Optical 3D Coordinate Measuring System in the creation of its 737 aircraft interiors as is now being implemented at Atech.
