I didn’t understand what people were asking me when I was a kid. The question would come in several different forms. Sometimes it was, “What are you?” Other times it was, “Where are you from?” I would answer with things I knew to be true, like, “I’m a girl,” or, “I’m a person,” or, “I’m from Maryland,” in a sincere, but failed, effort to satisfy my questioner.

I later came to understand that these people actually wanted to know my ethnicity. I grew up in a stereotypical melting-pot USA kind of place, otherwise known as Howard County, Maryland, where many neighbors and classmates were of various ethnic backgrounds. Even in this melting pot, I was different. I am of mixed ethnicity: My mom’s half is Afro-Caribbean by way of Jamaica, and my dad’s half is East Indian by way of the West Indies. I couldn’t be placed in one bin, and I was keenly aware from the questions I received that I was different. This made me want to understand this “otherness,” and that is what sparked my love of human genetics.

Ensuring the quality of a car’s performance and design, FARO 3D measurement technology solutions provide simple yet accurate ways of taking contact and noncontact measurements for quality control in automobile manufacturing and assembly.

Portable CMMs such as articulated arms can be used for rapid prototyping, analyzing car body panels, or inspecting a body-in-white, while large-volume laser trackers can be implemented for part inspection, alignment, machine installation, robot calibration, or reverse engineering tasks.

FARO has recently developed and introduced new portable metrology solutions that add measurement features and capabilities to its FaroArm product family: the FARO 8-Axis system and the FARO PRIZM Laser Line Probe.


The FARO 8-Axis system delivers innovative, real-time part rotation to streamline quality inspection processes.

The FARO 8-Axis system combines the portable FARO Quantum FaroArm or Quantum ScanArm portfolio products with a functionally integrated, yet physically separate, eighth axis.

Every year, Manufacturing Day brings attention to the career path that has financed millions of growing families throughout the decades—including mine. This attention also recalls the ongoing shortage of people to fill the thousands of available jobs in manufacturing. The same can be said for the science, technology, engineering, and mathematics (STEM) careers that go hand-in-glove with manufacturing. According to a 2018 Deloitte study, the lack of manufacturing workers could result in the United States losing up to $454 billion in the GDP.

The fact that so much wealth will go untapped by prospective employees is a poignant reminder of the need to shine a light on the various ways that some people and organizations are taking positive steps to mitigate the issue. One of the companies taking action is CNC Machines in Sanford, Florida. Founded in 2014, CNC Machines has grown to become one of North America’s top three used machinery dealers and named one of Inc. magazine’s 5,000 fastest-growing companies in the United States.

Attribute gauges are a type of measurement instrument or process that gives a binary pass/fail measurement result. Examples of attribute gauges include go/no-go plug gauges, feeler gauges, and many other types of special-purpose hard gauges. Many visual-inspection processes may also be considered attribute gauges. They are commonly used in manufacturing for product verification. Knowing the accuracy and capability of these measurements is therefore vital for a comprehensive understanding of quality in manufactured goods.

I’ve written a lot about how to evaluate the uncertainty measurements. My articles have ranged from basic introductions to metrology and uncertainty budgets, to more advanced topics such as sensitivity coefficients and Monte Carlo simulation. To date, all of the examples I’ve used have been for variable gauges. These are measurement instruments that give a numerical measurement result, on a scale, dial or digital display.

For more than 50 years, Tri-State Plastics has been honing its skills in thermoforming, CNC machining, die cutting, assembly, and fabricating plastic parts for government and military applications. A restructuring of company ownership saw the organization pivot toward the lucrative but challenging opportunity of aerospace manufacturing.

The pressure of global commerce has forced manufacturers to provide higher quality products at lower prices. Investing wisely in industrial inspection solutions has never been more crucial. Quality control, once perceived as a cost-center, has matured into a tool to improve profit margins. “Investing wisely” is a key concern here.

Making sure investment dollars turn the best ROI is incumbent upon every organization’s QA, QC, and engineering department. One way to do that is upgrade the capabilities of current hardware by investing in industrial inpsection software that can integrate with diverse inspection equipment throughout your facility.

In this QD Tech Talk videocast, we look at Nikon Metrology’s CMM-Metrology, a multisensor inspection software that runs on nearly all manual, CNC, and portable CMMs.

When you email friends, you don’t have to worry about whether they use Gmail, Outlook, Yahoo, or some other email provider. You just enter their email address, write your message, and hit send. The reason this works is because there are layers of standardized protocols that all the email clients have adopted so emails can seamlessly fly between users regardless of which client they choose.

Many other types of digital information exchange are not interoperable like email. Instead, if you want to share some data with another user, you often have to use the same software. I encountered this challenge both through my research as a science policy fellow with the National Institute of Standards and Technology (NIST) Public Safety Communications Research (PSCR) Division and my personal experience as a user of diabetes management technologies.

On factory floors all over the world, 3D printing has quietly moved from a prototyping novelty to an essential tool. Advances in printer technology and material science mean that today’s 3D printed parts are robust enough to hold up to real-world wear and tear, and precise enough for demanding production requirements. Today, when production engineers look to maintain quality, reduce cost, or boost efficiency, they are turning to 3D printing to get the job done on time and on budget.

Shortly after Ashley Furniture, the world’s largest furniture manufacturer, brought in the company’s first Formlabs stereolithography (SLA) 3D printer, one of their production engineers decided to try replacing machined alignment pins with 3D printed parts. If these held up to constant cycles and impact, the company could avoid the long lead times and minimum-order quantities of outsourcing the production of the alignment pins.

The engineer’s experiment was successful and led to more tests to find out where they could use 3D printing to improve fabrication and assembly processes. By examining how Ashley Furniture is driving best practices with 3D printing, we can better understand how to apply those insights to any manufacturing or assembly environment.

The aerospace industry is known for manufacturing parts with critical dimensions and tight tolerances, all of which must undergo demanding inspections. Given the scale of the controls to be carried out on these parts, it is hardly surprising that quality people in the industry prefer to turn to coordinate measuring machines (CMMs). However, directing all inspections to the CMM may cause other problems: CMMs are hyper-loaded and can generate bottlenecks during inspections, slow down manufacturing processes, and cause production and delivery delays.

Is it possible to unload CMMs so that they are fully available for the final quality controls? How can we improve manufacturing processes to produce more parts faster, and above all, of better quality? In the event of a quality issue occurring during production, is it possible to identify the root cause more quickly to minimize the delays that could impact schedules and production deliveries?
