The increasing variety of models in industrial production is placing growing demands on metrology systems. In sectors such as automotive, aerospace, and electronics manufacturing, components with complex geometries must be inspected in short cycles—without compromising precision or efficiency. Traditional clamping fixtures are often no longer suitable, as they require significant setup time and logistical effort.
With the PolyRobotAutomatedFixtureSystem (PRAFS), PROTOS-3D offers a digitally controlled alternative that, in combination with the ZEISS ScanBox, enables flexible and automated clamping technology. Unlike conventional mechanical setups, PRAFS systems use robotic units to position components individually—without mechanical adjustment or physical clamping. The integration of Virtual Clamping allows for stress-free data acquisition, stabilizing geometries using mathematical algorithms.
The newly introduced PRAFS 2410 and 2414 models are designed for components up to 1,400 mm in size. Both variants operate with four robotic arms and feature an integrated vision system. Using augmented reality, the system projects optimal contact points onto the component, whose position is continuously tracked by cameras. This visual feedback eliminates the need for manual alignment, allowing the measurement process to begin automatically as soon as the component is in place.
Stored clamping configurations can be centrally managed and recalled when needed. This enables PRAFS to support not only single-part and series production but also development processes involving high component diversity. With these capabilities, the system contributes to making quality assurance in 3D metrology more efficient, scalable, and resource-conscious.
