GOM has recently introduced the new ATOS 5 3D scanner for the inspection of surface elements of turbine blades, nozzles guide vanes.

The device carries out a wide range of measuring tasks in measuring areas from 170 to 1000 mm in length, the ATOS 5X is particularly effective when used on large surfaces and parts due to its strong, focused light.

We can also perform measurements for small details with dimensions from 100 x 70 mm2 to 400 x 300 mm2. The scanner is particularly suitable for inspecting aircraft turbine components such as blades and air-conducting structures. Their intricate edges and surfaces have been a challenge in 3D digitization so far

The sensor installed in the ATOS 5 also excels in the maintenance and repair of the nozzle guide vanes. The costs related to the MRO sector are high, the replacement of turbine blades may even exceed 10 thousand. euro. The combination of this technology with techniques such as additive manufacturing and adaptive machining can result in significant cost savings.

With the introduction of the device for the blade profiles, GOM offers a corresponding software update. The ATOS Professional and GOM Inspect Professional 2019 versions include new modules that, among other things, significantly simplify the analysis of demanding edge geometries.

All ATOS 5 scanners are distinguished by their high digitization speed and precise measurement data. Scanning in one measurement position takes only 0.2 seconds. 120 images per second can be developed. The sensor transmits data via a fiber optic cable. This means that the turbine blade is completely digitized in 3 minutes, the complete rotor in about an hour.

The resulting point cloud can be directly compared in the GOM software by comparing the surface with the CAD model or data from previous measurements. Within a minimum amount of time, an easily understandable overview of the dimensional accuracy of the part just manufactured, maintained or repaired is created. Due to the robust construction with protected optics, encapsulated electronics and a self-monitoring sensor, the measuring systems are also ideal for use in harsh industrial environments.

All sensors in the ATOS product series operate according to the triple scan principle. They project precisely striated patterns on the surface of an object that are captured by two cameras based on the stereo camera principle. Since the beam paths of both cameras and the projector are calibrated in advance, you can calculate 3D surface points from three different beam intersections. The result, even for reflective surfaces and complex objects with complex undercuts, is a mesh of complete measurement data with no holes or defective points.

The device can also be successfully used to control the quality of turbine blades in energy sector.
