Metrology Parts Publishes Guide to Video Measuring Machines

BAXTER, Minn. – – October 21, 2026 -- Metrology Parts has released "All About Video Measuring Machines," a guide covering six topics: how the systems operate, illumination and edge detection, differences from coordinate measuring machines (CMMs), benefits of optical systems, industry applications, and the shift to multi-sensor technology.

Video measuring machines measure the image of a part, not the part itself

The guide describes a video measuring machine as a robotic system engineered to eliminate physical variables that could cause measurement error. It uses three programmable illumination types: profile, surface and coaxial lighting.

Unlike contact-based CMMs, which use a mechanical probe, video measuring machines are entirely non-contact and rely only on light.
