The term ‘proficiency testing’ is one that every accredited calibration laboratory is quite familiar with. In basic terms it refers to a method of evaluating how well a laboratory is doing a particular calibration with respect to its claimed measurement uncertainty and how it fares with other participants.
It’s easy to take many of today’s technological marvels for granted, 3D measurement among them. The idea of simply pointing a “ray gun” of sorts at an object and obtaining all of its geometrical measurements would once have been solely the domain of Star Trek-ian science fiction.
As part tolerances tighten, both form and surface finish have a bigger influence on the size and function of the product. And with pressures on manufacturing to be more productive, it is no longer viable for checks of surface or form to be performed on a measuring system in a quality room.
Exova Group plc, the global testing, calibration and advisory services provider, acquired Insight NDT Limited (Insight), a South Yorkshire-based non-destructive testing (NDT) and radiographic inspection business.
Walking the floor of the International Manufacturing Technology Show in Chicago—between the 100,000-plus attendees and the thousands of booths—it was impossible not to notice the ongoing trend towards speed and automation in every aspect of manufacturing. It’s no different in metrology, as more manufacturers look to automate their inspection processes.
