As related to form metrology, a roundness measurement defines how closely the shape of a part approaches that of a perfect circle. 

For the most productive and efficient bore gage measuring solutions, it is beneficial to take some time to examine technology options. Choosing the right gage for your application will ultimately save tens of thousands of dollars and lead to increased accuracy. To begin the selection process, it is useful to review how you collect and record measurement data.

Mitutoyo announced the release of the RA-6000CNC, a custom-built CNC roundness/cylindricity measuring system with best-in-class accuracy.

We usually think of a “quantum leap” as a big thing, a great change or advance, and often when we are using this term, it is. Yet the term actually originates from atomic science and describes an electron moving from one energy level to another.

Most of the time form measurement looks at basic geometrical shapes: how round something is, how straight or even how flat it is.
