Who Should Attend This workshop is a valuable tool for individuals who inspect parts, create inspection plans, or approve inspection methods. Typical attendees include CMM operators, inspectors, gage designers, manufacturing engineers, technicians, supplier quality engineers Prerequisites Please be aware that this is not an introductory course. In order to understand the course content, you should have: • Completed 16 hours of formalized classroom training in GD&T • Experience interpreting or applying GD&T in an industrial setting • Have a working knowledge of the ASME Y14.5-2009 Standard A certificate from the GD&T Trainer: Fundamentals 2009 or Fundamentals of GD&T course is acceptable.
