Calibrating For Quality

  Just as you need to calibrate a gage in order to make accurate measurements, so a complete and ongoing program of machine calibration is a necessary prerequisite to any quality program.

Calibrating Threaded Plug Gages

  Just like gage blocks provide the basis for dimensional measurement, threaded plug gages are the fundamental tool used to verify that an internal thread is correct.

How to Become a Master of Deviation

  A few issues ago we wrote about how "less" can be "more," by purchasing lower grade master rings and discs and using their certified size their Master Deviation to actually improve the accuracy of your gaging process. Well the topic has sparked a number of questions and not a little confusion; primarily because we did not have space to talk abut actually applying this technique on the shop floor.

Repeatable Expectations for GR&R

  The process of determining the capability of a gage—GR&R—requires the analysis of the complete measurement process involving that gage.

What's Wrong With This Picture?

  On the Care and Feeding of Master Rings and Other Metrology Artifacts. Quality Assurance can only be as good as the measuring tools it relies on.

When less is more:
How a Class X Master Can Outperform a Class XXX

  A lower class master, certified to size, costs less than its higher class cousin, and when used with its certified master deviation, will provide a more accurate reading.
