Dimensional Inspection

A Closer Look: Verifying Dimensional Accuracy

Dimensional inspection, also called dimensional metrology, assesses the geometric characteristics of parts and products to ensure their compliance with design specifications. Dimensional inspection verifies the accuracy of product features that can affect reliability and functionality, and can be a critical step during product development or following production.
