June 15, 2021
This column is the fourth in a series of overviews on gage calibration to give you some idea of what is involved at this level of measurement. A book could probably be written on each subject and not do the job very well so I will continue keeping it simple to avoid completely ruining your day.

So how do we take the law into our own hands? The best, and only, approach is to surround ourselves with the tools and knowledge to reap our vigilante justice. To facilitate that knowledge, check out “The Changing Face of Additive Manufacturing Inspection,” “A Corporate Commitment to Quality Requires a Digital-First Approach,” and everything else we have to offer in this month’s Quality.

Neutron Radiography and Turbine Blades

Neutron Radiography Works on the Same Basic Principles as X-Ray Imaging Except With Neutron Radiation Instead of X-Radiation.
Willow Ascenzo
June 8, 2021
Air cooling is the most readily available means for keeping turbine blades from breaking or melting while the engine is running, and in order to get the most from the air streaming through the engine, turbine blades are cast with delicate cooling channels running through them. In the manufacturing process, though, these channels can become clogged. It's important that these defective blades be screened out as thoroughly as possible in quality assurance, and neutron radiography is the most effective nondestructive testing method for this purpose.

CMMs Go Collaborative

Is Your Coordinate Measuring Machine Future-Ready?
June 8, 2021
Digital transformation is placing urgent demands on coordinate measuring machines (CMMs) to be interconnected and communicative. Without the ability to collaborate with other systems and workers on the shop floor, CMMs risk becoming an informational black hole that prevents the flow of data required for smarter manufacturing.

Remote Visual Inspection an Important Part of the NDT Toolbox

Remote Visual Inspection has Provided Key Inspection Data While Maintaining Safety for its Operators.
Gregory James Weaver
June 7, 2021
Remote visual inspection (RVI) is a nondestructive testing (NDT) technique used for the visual inspection of an object where the person performing the inspection operates a piece of equipment from a distance. Most of the inspection applications used for quality purposes are carried out using three main types of equipment:  borescopes, unmanned aerial vehicles (UAV), and crawler robots. Find out more about their uses and advantages.
