Metrology is the science of measurement. This is where the people who do it for a living compare notes.
CMM programmers, calibration technicians, quality engineers, machinists, students, and the vendors who supply them. Bring prints, GD&T arguments, software problems, and equipment questions.
Vendors are welcome when they say who they work for. There is a monthly thread for services, sales, training, and jobs.
