Content AUKOM GD&T

  • Target group: Production metrologists, production engineers, developers, design engineers, QA heads
  • Prerequisites: For production metrologists: AUKOM 2 certificate recommended; For other target groups: None
  • Learning aims: The seminar provides in-depth knowledge on the topic of form & and positional tolerances in accordance with DIN ISO and ASME for advanced measuring technicians who work at interfaces to other departments and must communicate effectively. Design engineers, developers and production engineers gain an insight into the topic of form and positional tolerances from the viewpoint of the measuring technician who has to successfully implement the drawing specifications. An integrated understanding of measuring jobs and influencing parameters enables experts to communicate confidently with
  • interdepartmental areas and reduce measuring uncertainties; measuring results become more reliable and easier to compare. The minimization of costs and waste is supported.
  • Course duration: 3 days
  • Completion: Certificate
