Did you ever think reverse engineering and 3D could work together to create a windshield? Well it can and it has. Exact Metrology (EM) personnel from the company’s Brookfield, Wis., office used reverse engineering to help a vintage vehicle owner design his car’s windshield. EM is a 3D metrology service provider and hardware sales company.
Robert Smith is the owner of a one-off design car — a 1933 Speedster Coupe, which needed a special sized windshield that is no longer produced by any glass manufacturers, according to EM. Smith contacted Curved Glass Creations, located in Pompano Beach, Fla., inquiring if the company could supply the windshield he needed. Curved Glass Creations noted that it was unable to fulfil Smith’s windshield request. The company did reach out to EM with the unique windshield request on Smith’s behalf.
Joe van der Sanden from EM completed a scan at the client’s location using a Hexagon Absolute Arm 8525 with an RS6 scanner. According to EM, the Hexagon Absolute Arm 7-axis delivers tactile probing and laser scanning in a uniquely ergonomic package, and is ideal for high-end portable measurement applications. The Hexagon RS6 laser scanner is designed for high-speed and accuracy scanning, according to the company. It can scan up to 1.2 million points/sec with a scan rate of 300 Hz. The RS6 also has a wider laser stripe of 150 mm at mid-range and a visual guide that provides real time feedback for stand-off distance. According to EM, it was built using Systematic High-Intelligence Noise Elimination (SHINE) technology, which allows users to scan 99% of parts without touching the scanner exposure. With the Hexagon Absolute Arm 7-axis, the scanner can be removed if necessary and replaced without needing calibration, according to the company.
Once the scan was completed, the file format was delivered to Curved Glass Creations where it was able to make a custom windshield. Smith said that he had a unique experience reaching out to the 3D image industry to ensure the accuracy of his windshield glass created for his Alloway Speedstar.
“I never suspected my car built at Speedy’s Rod and Kustom’s would require such high technology,” said Smith. “I can’t thank Exact Metrology enough for their involvement and making it look easy.”
