Content level 1 Basic

  • Target group: Production metrologists
  • Prerequisites: None
  • Learning aims: The seminar lays and consolidates basic knowledge of production metrology for beginners and advanced metrologists. The didactic approach used in the seminar is based on the latest findings. The seminar covers the latest knowledge regarding dimensional tolerancing, programming basics, measurement process planning and the machine and sensor technology used. The enhanced understanding of measuring jobs and influencing parameters enables measuring technicians to reduce measuring uncertainties and thus to make measurement results more reliable and easier to compare. The minimization of costs and waste is supported.
  • Duration of course: 5 days, depending on previous level of knowledge
  • Completion: Exam, certificate
