Has your business ever dealt with a bottleneck caused by your inability to check parts quickly? Have you ever missed a shipment deadline because your coordinate measuring machine (CMM) couldn’t measure a production batch in a timely manner? Could you manufacture more parts if you…
The inspection and characterization of machine parts is still subject to research. Although optical means of measurement are very promising in respect to speed and precision, they are still not capable of measuring difficult-to-reach inner geometries. In this article, we will demonstrate our …
Exact Metrology
Josh Schradin, one of the 3D Scanning specialists at Exact Metrology’s Cincinnati facility, recently completed a computed tomography (CT) scanning project involving aluminum castings measuring approximately 12 in. x 6 in. x 6 in. and weighing 10 to 15 pounds.
The company’s new metrology-grade GE…

The 31st annual Coordinate Metrology Society Conference (CMSC), which concluded on July 23rd, delivered some fantastic career-enhancing opportunities for metrologists from 13 nations, representing leading research institutions as well as industries such as aerospace, space hardware, antenna,…
TE Connectivity
Connectors and lead wires provide the electrical connection between the coils of an LVDT position sensor and signal conditioning electronics. Choosing between a connector and lead wires, when specifying an LVDT or other sensor, often depends on the application and its environment.
Below are some…
NIST
Restoration is well underway for NIST’s 4.45-million newton (equivalent to 1 million pounds-force) deadweight machine, the largest in the world. The three-story-tall deadweight, comprising a stack of stainless-steel discs weighing about 50,000 pounds each, was disassembled last winter for the…

Researchers at the National Institute of Standards and Technology (NIST) have come up with a way to shrink a research instrument generally associated with large machines down to a pinpoint-precision probe.
This electron spin resonance probe employs a large-scale technique used for decades as a…
NIST
(NIST: Gaithersburg, MD) -- JILA researchers have designed a microscope instrument so stable that it can accurately measure the 3D movement of individual molecules over many hours—hundreds of times longer than the current limit measured in seconds.
The technology was designed to track the…

To make 3D scanning useful, you really need to understand the types of data files that can be exported or saved from the process. This is particularly important if you’re considering the purchase of a 3D scanner, or are paying for 3D scanning services.
If you’re paying for a service, you might…

Companies purchase scales because the value of goods entering or exiting a facility is based on their weight. Without assured scale accuracy, a company can lose thousands, if not hundreds of thousands, of dollars annually.
Depending on the requirements and type of weighing device, annual…

All the technical journals are abuzz with the changes to ISO 9001:2015. One significant paradigm shift is to a risk-based management approach. Most companies already apply risk-based thinking in their planning process for organizational management. This article will take a narrowly focused…

Creating quality coordinate measuring machine (CMM) measurement programs takes time, and production cycles are often delayed while waiting for the measurement programs to be created. But software that works directly from model-based definitions can drastically decrease that time.
The move from 2D…

I have heard people say that geometric dimensioning and tolerancing (GD&T) is a black art, and I agree—it can almost seem that way sometimes. My experiences in coordinate metrology throughout the past 20 years demonstrate a widespread lack of understanding, confusion, and even resentment for…
