NUMBER OF POINTS REQUIRED FOR CMM MEASUREMENT 1

[kmansoor]

IS THERE ANY NORTH AMERICAN STANDARD THAT SPECIFY HOW MANY POINTS ARE REQUIRED TO MEASURE A FEATURE USING CMM MACHINE. I HEARD THE BRITIS STANDARD BS7172 SPECIFIES THIS REQUIREMENT FOR EXAMPLE 9 POINTS FOR A SURFACE 15 POINTS FOR A CYLINDER.
