Dimensional Inspection

A Closer Look: Verifying Dimensional Accuracy

Dimensional metrologyDimensional inspection services, also called dimensional metrology, assess the geometric characteristics of parts and products to assure 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.

LTI Metrology at Laboratory Testing Inc. (LTI) performs dimensional inspection on surface and specialty features of machined parts and products, including internal and external fastener threads. First article inspection and third-party dimensional inspection services are performed according to NAS, MS and ANSI specifications. Our dimensional inspection and measurement capabilities are accredited to ISO/IEC 17025 by A2LA.

Optical comparator dimensional inspectionOur dimensional metrology inspectors are thoroughly trained to interpret customer prints and use CMM inspection services and Smartscope technology for timely, reliable and repeatable dimensional inspection measurements. The dimensional inspection equipment at LTI Metrology has both contact and non-contact measurement options including a multisensor Smartscope with optical and touch probe capabilities and a Brown & Sharpe CMM Measuring Microscope with zoom magnification. Our conventional measuring equipment includes thread, plug and height gages, micrometers, calipers and surface plates.

LTI gives customers the measurement information they need for product verification and quality control, so they can get their products to the marketplace and stay ahead of the competition. All of the instrumentation used in the dimensional metrology lab is traceable to NIST (National Institute of Standards and Technology).

For the highest degree of accuracy, we minimize factors that contribute to measurement uncertainty. At LTI, dimensional inspection services are performed in an environmentally-controlled laboratory with regulated temperature and humidity.
