AUKOM Level 2

December 7th – 11th, 2020

  • Target group: Production metrologists
  • Prerequisites: Successful completion of Level 1 Test
  • Learning aims: The Level 2 course furthers basic knowledge of production metrology for advanced measuring personnel. The didactic approach used in the class is based on the latest findings. The course content comprises the latest knowledge on form and positional tolerance, test plan interpretation, programming, monitoring, and the machine and sensor technology used. An enhanced understanding of measuring jobs and influencing parameters enables metrologists & measuring personnel to reduce measuring uncertainties and by doing so, making measurement results more reliable and easier to compare. The minimization of costs and wasted materials is supported throughout the chapters of the course.
  • Course duration: 5 days (4 Days of Instruction, 5th Day for Exam)
  • Completion: Certificate upon successful completion of exam
  • Lunch provided daily, Monday – Thursday.
