Dimensional Metrology Lab

Student working on lab project

Metrology is the science of measurement. A metrologist is a person who practices one or more of the methods employed in measurement. All measurements are relative in that they are comparisons of some known standard. Some ways to measure things are by weight, pressure, resistance, temperature, quantity, capacity, etc.

Metrology in the Department of Engineering Design, Manufacturing and Management Systems serves many majors which are related to manufacturing. In our modern industrial society we need to be able to produce manufactured goods that are made to exacting standards, able to be repaired with interchangeable parts, and be consistent in their production so that costs can be reduced.


Although all of the aforementioned arts of measurement are important, the course entitled "Dimensional Metrology", focuses on the dimensional characteristics of products. Students successfully completing this course will:

  • Understand the purpose of critical dimensions in manufacturing.
  • Understand the principles and operation of precision measurement tools and equipment used in modern manufacturing.
  • Understand the fundamentals of inspection methods and systems.
  • Be able to analyze simple parts for dimensional accuracy and functionality.
  • Be able to measure the manufacturing process using deterministic metrology through statistical techniques.
  • Be able to design simple inspection gage and checking fixtures.
  • Be able to design simple productive tooling that assures duplicate parts.
