Too much data?

[[Ca...]]

I'm sure I'm not the only person who's dealt with this.

I'm looking for suggestions on how to handle being told: "Your numbers can't be right because scanning collects too much data for the machine understand."

FYI: I'm following the general practices suggested in the Cookbook.

I mean.... some people who manufacture the parts don't like to see what the reality is. But ultimately, we wouldn't put 5 pylons in a parking lot and try and calculate the diameter of the earth, would we?

I agree with Laura. On an almost weekly basis I debate with someone about how to evaluate the data.

No, you definitely need 6 cones before you can even start calculatin'

The more the better, especially if you're talking about form.

But I thought 4 was the minimum number of points for a sphere.

You must be talking to an old tool and die guy. They never trust anything that isn't a dial indicator.
The only thing I can think of is to describe to them a pin that must fit into a drilled hole. The pin is out of round with a tri-lobe shape. A micrometer measurement will give you a false reading of the true diameter since it is only contacting two points around the pin. With a CMM, you can measure as many points around the diameter as you want, which will give you a better picture of what the actual diameter is given the proper evaluation (minimum circumscribed).
Although generally, there's not much you can say that will convince these old tool and die guys that the data is sound.
