UNICAL: Smarter Calibration, Faster Verification
UNICAL is Hexagon’s advanced software designed to transform machine tool and CMM calibration. It replaces days of work with hours of insight. Using a patented interferometric, multilateration method, UNICAL measures errors directly at the tool tip to deliver complete, traceable, and full-volume accuracy across your machine’s entire workspace.
This innovative approach captures six degrees of freedom (6DOF) per axis plus squareness, providing a comprehensive understanding of machine performance. For manufacturers, this means reducing measurement time by up to 80% compared to traditional methods, reclaiming valuable production hours while ensuring unparalleled precision. The process is streamlined and automated, empowering operators to achieve expert-level results with minimal training.
