IIGDT World International Institute of
Geometric Dimensioning & Tolerancing
 
 
Level 5
Applied Dimensional Metrology
Course Outline

Course Objective To provide hands on insight to intermediate and advanced applications and analysis of 2D & 3D measurement instruments used to determine full compliance to mechanical drawings. Gain insight to key error influences that can provide tremendously different measurement results and to know how to optimize the measurement programs to effectively reduce the measurement error/bias. Gain insight to the strengths and limitations of Gage Repeatability and Reproducibility (GR&R) by making visible some key error influences that can cause significant biases in the results and show how to test and correct for these biases.
Course Length 2 Days (16-hours)
What You Will Learn 3D Measurement
 
  • Traceability of measurement to national laboratories
  • Limitations of 1D and 2D measurements
  • Understanding key error influences and how to test for and correct
  Single Sensor and Multi-Sensor Coordinate Measuring Machines
 
  • Video sensors, laser sensors, whitelight interferometers and micro probes
  • Manual & automatic CMMs, single point touch sensors, scanning sensors and measuring arms
  • 3D surface and form instruments
  • Introduction to traceable artifacts and value of interim artifact testing
  Methods for analyzing and interpreting data results (2D & 3D)
 
  • Working with CAD and measurement data (point clouds)
  • Analytical software – strengths & weaknesses
  • Understanding least-squares -vs- Minimum zone fitting
  • Understanding criticality of simultaneous requirements within the standards
  Measurement Uncertainty/Traceability
 
  • Gage Repeatability & Reproducibility(corrected and uncorrected error sources
  • Introduction to the limitations of GR&R and benefits of measurement uncertainty
  Each subject includes an overview of the tools is followed by a demonstration of best application practices and a discussion of calibration issues and measurement uncertainty factors. Each session includes hands-on lab activity and includes discussions on understanding key error influences and how to test for and correct them.
