Our new article in Cal Lab Magazine covers a lot of ground about what your can, and can’t, expect from your roughness or roundness gage. Knowing the strengths and limitations can help you avoid errors and misinterpretations, and expensive mistakes on the shop floor.
How do you ensure that your roundness or roughness system is calibrated? In our new Verify and Calibrate video series, we’ll be showing you how to calibrate roundness and roughness measurement instruments—and how to verify the calibration for ongoing accuracy. In our first video, we’re using a Flick standard to verify the calibration of an…
The term “included angle” can be confusing as it’s come to have two meanings for diamond stylus tips. Included angle = Included flank angle = cone angle In the ASME B46.1 standard, “included angle” is used as a synonym for “included flank angle,” the angle formed by the two sides of the diamond tip. It’s…
We recently took a call from a manufacturer who was trying to tell whether a production issue was due to a change in the process or a change in the measurement instrument. We asked how they determine whether the instrument was measuring accurately, and they said the manufacturer calibrated it, months before. We asked if…
Replacing a metrology system can be a huge expense, so keeping older gages in service is vital for many businesses. Older systems need support to keep going, but even instruments with a lot of wear and tear can continue to perform reliably. So, how bad can a system get, but still be useable? It just…
From handheld roughness gages to high-end interferometers, there’s a vast array of instruments available to measure roughness and roundness. But not all instruments are equal. Knowing the strengths and limitations of your gage can help avoid measurement errors that lead to expensive mistakes on the shop floor. Measurement instrument manufacturers offer systems with many different…
Do you think of EMI Gage, Inc. as a probe vendor? You’re right! But we’re a lot more than that. Our ISO 17025 certified calibration team help hundreds of companies to stay in compliance each year. Unlike OEM instrument suppliers, our metrologists can calibrate many brands of texture, form, contour, and roundness gages—even on the…
