Level 7
Measurement Uncertainty
Course Outline
|
|
Course Objective
|
Provide a foundational understanding of measurement
uncertainty per the ASME B89.7.2 Standard on “Guidelines for the
Evaluation of Dimensional Measurement Uncertainty.” To solidify
fundamental to intermediate information in interpretation,
application and analysis of measurement uncertainty using
multiple measurement instruments and sensors to determine
compliance to mechanical drawing requirements; To understand the
strengths and weaknesses of the GR&R approach and a total
assessment of measurement uncertainty.

What You Will Learn |
Understand conventional Gage Repeatability and Reproducibility
studies and describe the strengths and weaknesses of the GRR
approach and a total assessment of measurement uncertainty |
|
|
-
Complete a process demonstrating a full
analysis of measurement capability including the role of a
GR&R within that analysis
-
Evaluate implications on measuring for
conformance -vs- measuring for development or process
understanding -vs- process monitoring
|
|
|
Understand the role of ASME B89.7.3.2 in the development of a
measurement uncertainty management program |
|
|
-
Understand the definition of the “measurand”
and the associated “validity conditions”
-
Understand decision rules for accepting
and rejecting inspected parts
-
Understand process capability measures
and their interaction with gage capability measures
-
Understand rules and procedures for
tolerance to uncertainty ratios
|
|
|
Understand sources of uncertainty common to frequently used
measurement devices: precision hand tools (1D), video sensors
(2D), touch trigger probes and scanning probes (3D) |
|
|
-
Develop a measurement uncertainty
budget for the sensors described above including the
interaction of environmental, part, set-up, point density,
fitting algorithm, operator effects, etc.
|
|
|
Understand the process for continual improvement in reducing measurement uncertainty sources to acceptable levels and maintaining those levels |
|
Who Should Attend
|
Anyone with the responsibility of establishing measurement
procedures and analyzing the implications of various measurement
methods and techniques for achieving precision measurements.
Inspection planners, specifiers and decision makers of
engineering and measurement requirements, specifiers of
manufacturing processes and measurement applications and anyone
doing statistical analysis of design, manufacturing or
measurement data. Engineers, designers, metrologists,
technicians, machinists, toolmakers, senior inspectors, senior
technicians, statisticians and mechanical engineers at all
levels.

Prerequisites |
“GD&T - Advanced Applications” and “Applied
Dimensional Metrology” All individuals must have an advanced
working knowledge of GD&T and a foundational knowledge of
Applied Dimensional Metrology to be successful in this class.
