An act of technical sabotage has been detected on a glass production line. The perpetrator introduced a microscopic magnetic spacer into the head of a waterjet cutting robot, causing an imperceptible misalignment. The fault was identified through a 3D pipeline combining GOM Inspect for metrology and Rhino 3D for reverse modeling.
3D Pipeline: GOM Inspect and Rhino 3D to detect microns out of place 🛠️
The detection process began with a high-precision scan using GOM Inspect, which revealed an angular deviation of 0.02 degrees in the head. This data was imported into Rhino 3D to reconstruct the actual geometry of the assembly. By comparing the nominal model with the scanned one, an additional volume of 0.3 mm³ was identified at the head joint. Physical inspection confirmed the presence of the magnetic spacer, an object designed to go unnoticed in industrial environments.
The magnetic spacer: the lost screw that never existed 🧲
Someone thought inserting a 0.3 mm magnet between two metal parts was a brilliant idea. And it was, but for causing trouble. The spacer did not cause a breakage, only a crooked cut of 0.1 mm on each piece. The result: thirty sheets of glass discarded before anyone noticed the robot had started cutting as if it were drunk. A bad joke that cost time and material, but at least it proved the metrology team works.
