Unless I am completely missing something, I don't see how it would be possible to stuff that into a 10mm hole and check an inside corner radius at the bottom of the bore.
I might not be clear on the app... Is this a through hole or a bottom corner radius in a blind hole bushing?
I think maybe I'm the one that may not be understanding....
What shape of bushings doo you guys generally make?
Why pass on a 10mm hole?
How would a laser scanner do what you want?
On a 10mm circle the three points of your setup would be on such different planes that it would be nuts. Even if you dropped one and went with two points - it's still partly around the corner...
And it will not tell me if it is the tool is worn or chipped and producing a funky geometry.
I don't know the first thing about lasers. I am a machinist, not an electronics junkie. But they keep advertising about the abilities of these new laser scanners and how increadibly accurate they are.

For occasional checks I'd use reprorubber quicksetting putty and a optical comparator.
A laser scanner won't help, the laser spot is too big.

Is the concern rad shape/size or position?
Ass-u-ming that this is bigger than 10 pc runs you may be able to control this with simple hard gauges. A point off each wall and one in the middle of the rad may give you the info you need.

Shape/size/location is a mess really as I am making the coners all to print - while leaving grind stock inside and out. So I have a tapered bore for .030 where I am getting to final bore size, and then creating the rad, and then facing the part on a slight angle 'till it run out in an opposite slight angle from the OD tool that made the same taper/rad/face routine on the outside.
So the best I am able to doo currently is to check the ID of the rad with the tips of a set of calipers to be close to after grind dimmenssions. I forget the actual dimm, but lets say .014 to .020" rad (?) I check size with the calipers to make approximate D with finish grind, while qualifying that the rad is good by spinning it on the end of my finger.
For eny other customer - I am sure that what I have done so far would be just fine. But this is Big 3 / small volume (for now) / military. When I quoted - I knew it was military. I did NOT know that Big3 was involved. No-body has asked me to qualify the rads yet, but I am trying to figger out what it will take to be able to doo that.
The 10 yr projection has some awfully ... ambitious ... (
) volumes, but for now it is looking like a cpl thou a month maybe? These are really cheap and simple bushings, that can git to be very expensive if all the T's need dotted and I's all need crossed.
