What is the best equipmenbt to gauge an ID bore; what gauge will give accurate Gage R & R studies as the best possible gauge? Is a Sunnen Gauge better than the CMM for ID's when there are problems with roundness?

DAWN,
THE FOLLOWING ARE ONLY MY VIEW POINTS FROM MY PERSONAL EXPERIENCE.
1) THE CMM WILL PREFORM ROUNDNESS BETTER
2) THE SUNNEN GAUGE IS NOT AS GOOD AS A 3-POINT BORE GAUGE.
HOWEVER THE BORE GAUGE WILL SHOW YOU WHERE YOU ARE OUT OF ROUND. IF YOUR CMM DISPLAYS GRAPHICS ON MULTIPLE POINT FEATURES. IT WILL ALSO SHOW YOU WHERE YOU ARE OUT OF ROUND.
3) THE BORE GAUGE SHOULD GIVE A BETTER R&R BECAUSE YOU CAN CONTROL THE POINT OF MEASURE EASIER.

DAWN,
MOST ALL OF THE MAJOR MANUFACTURERS CARRY 3-POINT GAUGING. BEFORE YOU RUSH OUT AND BUY REQUEST INFORMATION FROM SEVERAL OF THEM. DEPENDING ON YOUR PROCESS THERE ARE DIFFERENT TYPES OF 3-POINT MEASURE. DO YOU HAVE A MANUAL OR CNC-CMM? IF IT IS CNC YOU CAN CONTROL WHERE YOU MEASURE AND COULD DO SOME SAMPLING BEFORE INVESTING IN A GAUGE THAT MAY NOT BE NESSARY. CHECK ALL YOUR OPTIONS AND PRICING CAN BE DONE THROUGH YOUR LOCAL INDUSTRIAL SUPPLY HOUSE.

Sunnen gages have 3 prongs and can measure tenths. Why would a bore gage be more accurate?
