Latest Dimensional Metrology, Inspection and Quality News
Increasingly stringent precision requirements in the age of Head Up Displays and Augmented Reality combined with growth projections, as well as continually growing added value in production processes through new interaction concepts and functions, such as integrated displays and various coating systems, transparency on demand are demanding ever more powerful measuring tools for monitoring and controlling process and product quality by glass manufacturers. Manufacturing yield and product quality more than ever depend on prompt feedback in the production chain.
For over 15 years nokra has been successfully supplying laser-based inline geometry measuring systems to production lines of major windscreen manufacturers. With its new product series alpha.glass, nokra offers unprecedented possibilities for measuring automotive glazing: scanning of areas enables direct ROC control, and an unlimited number of measuring points can be monitored. The newly developed high-sensitivity sensors allow differentiation between individual glass surfaces, which means that it is now possible to measure individual panes. In doublet manufacturing, direct gap evaluation is achieved, and in singlet press bending, virtual gap evaluation can be realized.
Singlets – doublets – laminates: alpha.glass fits all parts of the manufacturing process and can be used in all common manufacturing process types, starting immediately behind the bending furnace right through to final control. Due to the expanded functionality, the application area is no longer limited to windscreens, but also includes back lites and side lites.
The alpha.glass software offers dynamic recipe management for any number of different types of windscreen. In every recipe, an unlimited number of measuring points and ROC areas with their respective tolerances can be stipulated. The measuring data in the productive operation is automatically evaluated in real time. Communication is achieved through Profibus/Profinet and TCP/IP and is industry 4.0-capable.
