Metrology Glossary: Universal Length Machine

What Is A Universal Length Machine?

A Universal Length Machine (ULM) is a precision measuring instrument used for the accurate assessment of both the external and internal dimensions of items. This highly adaptable device is suitable for gauges, tools, and machined components among a broad array of objects. ULMs are typically equipped with a three-axis (X, Y, and Z) movable table, enabling operators to precisely position the object under examination. The machine also incorporates a probe capable of adjustable placement to measure various aspects of the object. This probe is usually equipped with a sensor to determine the distance between the probe and the item being measured.
