Geometric dimensioning and tolerancing is a standardized system used in engineering and manufacturing to define the allowable variation in part geometry. It uses symbols, rules, and tolerances to clearly communicate how a part should be manufactured and inspected. GD&T helps ensure that components fit together and function correctly, even when minor variations occur during production. This system reduces ambiguity in technical drawings and improves consistency across suppliers and production teams. Geometric dimensioning and tolerancing is widely used in CNC machining, mechanical design, and industrial manufacturing.
At Hannover Messe 2026, German manufacturers and startups showcased AI-powered robots for industrial applications, with Chancellor Friedrich Merz backing wider AI adoption as Germany seeks to close the gap with China and the U.S. in physical AI.
NVIDIA and more than a dozen industrial partners used Hannover Messe 2026 to demonstrate AI-driven manufacturing systems already operating in live production environments, from humanoid robots in electronics factories to vision AI agents on automotive assembly lines.
More than 3,000 exhibitors at Hannover Messe 2026 showcased physical, generative, and agentic AI systems moving from demonstration into production, with Siemens, Schneider Electric, NVIDIA, and Microsoft presenting deployments already delivering measurable results on factory floors.
