Dimensional Inspection and Testing Services

Tolerances are an essential part of manufacturing. Despite our best efforts, no dimension can be exact; instead, engineers settle upon an ideal target with an acceptable level of deviation. The tighter the tolerance, the more expensive it is to fabricate, so it is equally important to avoid over specifying dimensions as much as underspecifying. Dimensional inspection confirms manufacturing outcomes meet their stated design intent and can uncover process control errors that may undermine acceptable yield.

Taking a Closer Look With Dimensional Inspection

Dimensional inspection, also known as dimensional metrology, assesses the geometric characteristics of machined parts and products to verify their compliance with design specifications. Dimensional inspection services ensure the accuracy of the product features that can affect reliability and functionality. Inspection is often a critical step during product development or following production.

LTI Metrology can perform CMM dimensional inspection on machined parts, products, and fasteners in sizes up to 18″ x 20″ x 16″. Smartscope and CMM inspection equipment is programmable for automated dimensional measurement, providing repeatability and reliable accuracy for large-quantity orders. The technicians at LTI Metrology also provide traditional dimensional metrology services using various measuring instruments, including thread gages, plug gages, height gages, micrometers, calipers, and surface plates. Programmable and traditional dimensional metrology services are A2LA accredited to ISO/IEC 17025 and performed according to NAS, MS, and ANSI specifications, while all inspection results are traceable to NIST.

Customers receive reliable measurement data for product verification and quality control to get their products to the marketplace and stay ahead of the competition. We minimize factors contributing to measurement uncertainty for the highest degree of accuracy. Inspections occur in an environmentally-controlled laboratory with regulated temperature and humidity to ensure result reproducibility.

See How LTI’s Dimensional Inspection Services Measure Up

Dimensional inspection quantifies representative sampling and full-assembly installations, ensuring that the physical measurements of products meet all design and safety goals. While measurements must be precise, the processing speed is also vital: automated and computer-assisted evaluations are indispensable when tolerance testing of components numbers in the thousands. In addition to operating this equipment, technicians may need to rely on more tactile forms of traditional measurement tools. Whether by hand or computer, LTI Metrology offers industry-leading services at our state-of-the-art facility for all your dimensional inspection needs.
