QUALITY MEASUREMENT Why Air Gaging Still Matters

Hole Measurement History Pressure, Flow and Variety What to Ask For Seek A Smooth Surface Another 90 years? Sidebar Tech Tips Links Practical dimensional air gages began to appear in the late 1930s. "This was when flowmeter instruments with operating pressures of 10 psig were developed," says Don Moors, president of Western Gage Corp., (Camarillo, CA). "About the same time dial-type back-pressure instruments with gage pressures at the midpoint of the scale ranging from 20 to 25 psig were developed. Both of these designs proved practical for many gaging applications, with many proponents of both systems." During the 1940s, there was incr See more on qualitymag Roughness measurement of leaf surface based on shape Surface roughness has a significant effect on leaf wettability.

What are the grades of a gauge block?What are the grades of a gauge block?There are 4 tolerance grades; 0.5, 1, 2, and 3. Grades 0.5 and 1 gauge blocks have lengths very close to their nominal values. These blocks are generally used as calibration masters. Grades 2 and 3 are of lower quality and are used for measurement and gauging purposes.The Gauge Block Handbook - NIST

Defining Surface Roughness Measuring Surface Roughness Controlling Surface Finish Sources and Further Reading Because surfaces in engineering applications must be within desired limits of roughness for quality purposes, the ability to precisely measure roughness is crucial. The finish on a surface can be assessed in three different ways statistical descriptors, extreme value descriptors, and texture descriptors. Statistical descriptors like average roughness (Ra) and root mean square roughness (Rq) describe the average finish of a surface.
