Fundamentals of Metrology and Quality

Metrology is an important component in manufacturing because it provides a rigorous method for Quality personnel to manage risk and uncertainty.  To mitigate risk successfully and develop techniques for problem solving, it is important to evaluate sources of uncertainty, verification, and non-conformance.   This seminar is intended to introduce the various principles associated with uncertainty of measurement; to explore the history of measurement, and to clearly identify calibration, true values, errors, uncertainty, traceability, random and systematic effects, repeatability and reproducibility.  It will help you to understand why MSA can sometimes give wrong results; to know when uncertainty evaluation is required; and when a Gage R&R study is sufficient.

What Will You Learn

By attending this seminar, you will be able to:
  • Evaluate the uncertainty of measurement
  • Explain the differences between errors, repeatability, reproducibility, and uncertainty
  • Determine whether a Gage R&R Study is fit for your purposes
  • Detect when to use uncertainty evaluation
  • Judge whether a measurement is capable

Is This Course For You

This course is designed for engineers who work in the fields of quality, manufacturing and production, who would like to understand the fundamentals of Metrology and uncertainty of measurement. Individuals in other professional disciplines who are interested in enhancing their knowledge in this arena will also find this course helpful.
