I don't know what this true position on the hole is constraining. Bolt circle diameter or orientation of the hole maybe? Trying to determine if I need to measure the hole as a cylinder. Appreciate the help.
It's essentially the hole pattern to itself.
Probably will have to a manual alignment using two of the bolt holes to offset before going to DCC.
Create a cylinder on Datum A, then level and set the origin on it.
Measure the bolt hole circles and do a 2D best fit rotary alignment. (Terminology may not be correct.)
Then report the position of the bolt hole circles.
Same here. I would though remind engineers to make one hole preferably the top (where the dim line is point to) as a datum hole or write on the print to clock to that hole. A CNC machinist always starts to drill 1st hole somewhere. Engineers should designate that specific hole as tertiary datum hole. You need to clock the cmm alignment to something to make the machine find rest of holes.
