Measuring height and width of glowing steel castings
The laser scanners have to be operated in an extremely hot environment and are subjected to considerable thermal radiation arising from the cast parts. Therefore, they have to be cooled down by a water-based cooling system and covered with insulating material.
This task is a typical application of the high-resolution QuellTech 2D/3D Q5-880 Blue Laser Scanners. Two of these units are placed at the left and at the right of the measuring objects, at a defined inclination angle. Blue laser light in this case is a prerequisite, as the cast parts are red-hot, hence emitting in the red spectral range. Additionally, the client was in need of a software solution for the project, so a 3D point cloud processing application was implemented, performing inline and evaluating width, height and angle results.
With this QuellTech solution, the customer is able to inspect continuously the product quality, simultaneously avoiding scrap. He uses the same system for more than 10 different types of castings. Errors caused by manual inspection are considerably reduced, and safety for personnel is enhanced.
