Talk:ANOVA Gauge R&R
From Wikipedia, the free encyclopedia
I am new to GR&R and have been given the resposability of doing MSA on all our equipment. Looking for some help in What is MSA.

I HAVE A QUESTION: CAN ANYONE TELL ME WHAT ARE GENERALLY ACCEPTED MINIMUM GUIDELINES FOR AN EFFECTIVE GR&R STUDY WITH RESPECT TO THE SAMPLING MATRIX? THIS WOULD BE IN A FACTORY PRODUCTION SETTING MEASURING MACHINED METAL PARTS WITH CALIPER, MICROMETER, ETC. MY EXPERIENCE HAS BEEN WITH 3 X 3 X 5 MATRICES (3 OPERATORS, 3 REPETITIONS OF MEASUREMENT PER OPERATOR ON 5 SAMPLES), AS WELL AS 3 X 3 X 10. WOULD 4 OPERATORS X 3 REPETITIONS X 3 SAMPLES BE STATISTICALLY INAPPROPRIATE?
THANK YOU,

I need to know what kind of study will help me to evaluate an attribute gage. I know I can't use gage R&R but I still need to know how reliable my gage is. Thanks for your help. L.R.

Gage R&R does not restrict number of operators. For variable GR&R, the minimum requiement is 2 operators, 10 parts & 2 repeats. You can use as many operators along with as many parts you think would be necessary to capture the total part variation. --136.1.1.101 23:36, 5 August 2007 (UTC)
