Summary:

Using repeatability and reproducibility analysis to measure the measurement error in measurement systems.

Screen Shot and Video:
Description:

Purpose:

Gage R&R analysis is a statistical tool that measures the amount of variation in the measurement system arising from the measurement device and the people taking the measurement.

Installation:

Download the file and drag-and-drop onto Origin. A new corresponding icon will appear in the Apps Gallery window. A toolbar will appear when launching the APP.

Note:

Worksheet data in Origin are organized by row index number. For instance, in a gage study, each measurement made on a part might be matched by row index number to a part number, an operator number and a replicate number.

• Type 1 Gage Study
A Type 1 study is used for evaluating the repeatability of a measuring process.
Key input parameters: Measurement Data, Reference, Tolerance, Limit Type: Two-sided or one-sided (Upper Only, Lower Only), Percent of tolerance for calculating Cg, Study variation (num of SD).
• Gage Linearity and Bias Analysis
Assess the linearity of gauge response across the expected range of measurements.
Key input parameters: Part Numbers, Reference Values, Measurement Data, Process Variation (optional)
• Gage R&R Study(Crossed)
In a crossed study, all parts are measured by all operators.
Key Input Parameters: Part Numbers, Operators, Measurement Data, Method of Analysis (ANOVA, Xbar and R), Gage Tolerance, Study Variation (number of standard deviations), Process Tolerance (specification limit), Limit Type: Two-sided or one-sided (Upper Only, Lower Only), Historical Standard Deviation.
• Gage R&R Study(Nested)
In a nested study, each operator measures a unique set of parts.
Key Input Parameters: Part, Operator, Measurement Data, Gage Tolerance, Study Variation (number of standard deviations), Process Tolerance (specification limit), Limit Type: Two-sided or one-sided (Upper Only, Lower Only), Historical Standard Deviation.
• Gage R&R Study(Expanded)
In an expanded study, each operator measures a unique set of parts.
Key Input Parameters: Part, Operator, Additional Factors, Measurement Data, Model, Fixed Factors, Nested Factors, Gage Tolerance, Study Variation (number of standard deviations), Process Tolerance (specification limit), Limit Type: Two-sided or one-sided (Upper Only, Lower Only), Historical Standard Deviation.
• Attribute Gage Study
In attribute gage study, attribute measurement system is evaluated.
Key Input Parameters: Part, Reference Values, Acceptance Counts, Total Number of Trials, Upper/Lower Limit Value.
• Create Gage Worksheet
Key input parameters: Number of Parts, Number of Operators, Number of Replicates, Randomization (None, All Runs, Runs within Operators).
