Type 3 Gage R&R Study

QI Macros Template Makes It Easy to Run a Type 3 Gage R&R Study

  • Typical Gage R&R studies use 10 parts, 2-3 appraisers and 2-3 trials (3 x 3 x 10).
  • A Type 3 Gage R&R study uses 30 parts, one appraiser (CMM machine), 5 trials (1 x 5 x 30).

To Conduct a Type 3 Gage RR Study Using QI Macros:

Open the Gage R&R Template and click on the Type 3 GRR tab.

  1. The input area is 30 columns (parts) x 5 rows (trials). Input your measurements into these cells.

    6 (AIAG Standard): Introduced in AIAG 3rd Edition, this constant assumes that 99.73% of data falls within the Standard Deviation of the mean.

    5.15 (Alternate multiplier): Introduced in AIAG 1st Edition, this old AIAG standard assumes that 99% of data falls within the Standard Deviation of the mean.
