Level 3
Introduction to Dimensional Metrology
Course Outline

Course Objective To provide hands applications on how to use shop level measurement equipment and to understand fundamental error sources and limitations applied to each. To provide insight on how to test the calibration on instruments using precision artifacts to ensure gages do not drift from their original calibration and induce an undesirable bias. Students will be introduced to how to repeatability and reproducibility (GR&R) of measurement instruments.
Course Length 2 Day (16-hours)
CEUs 1.6
Course Content Precision Hand Tools and Hard Gaging
 
  • Micrometers, calipers, indicators, pin & ring gages and thread gages
  Bench Top Measurement Instruments
 
  • Height gages, bore gages, fixed gages and laser micrometers
  Surface and form instruments
 
  • Profilometers, contour measurement, roundness and cylindricity systems
  Optical measurement systems
 
  • Optical comparators, and toolmakers microscopes
  Introduction to coordinate measuring machines
 
  • Manual & automatic CMMs, single point touch sensors & scanning sensors
  Methods for analyzing and interpreting data results
 
  • Introduction to Gage Repeatability & Reproducibility (GR&R)
  • Introduction to measurement error sources (variability & bias)
  Each session will include an overview of the tools followed by a demonstration of best application practices and a discussion of calibration issues and measurement variability & bias factors. Each session includes hands-on lab activity.
Targeted Audience Anyone requiring a foundational understanding of measurement systems used for measuring mechanical components and assemblies for proof of compliance versus process feedback. Specifiers and decision makers of engineering requirements and specifications as well as specifiers of manufacturing processes and measurement applications and anyone doing statistical analysis of design, manufacturing or measurement data. Engineers, designers, metrologists, technicians, machinists, toolmakers, designers, senior inspectors, senior technicians, statisticians and mechanical engineers at all levels.
Prerequisites GD&T Intermediate Principles! An interpretation level knowledge of GD&T is required to allow all participants to be successful in this class. If students do not have this level of understanding, they will not understand “why” measurements are to be taken a particular way.
  The Introduction to Dimensional Metrology Course Outline is available in PDF format.
