O-Ring Groove Measurement Method in CNC Machined Parts

We are using CNC lathe for machining a internal O-Ring groove. Can any one help me proposing inspection method other than digital groove caliper prior to removing the part from lathe. Size 3mmX42mm.
 
Would it be possible to use a probe head combined with a disc stylus in your machine? That would solve the problem, but may be a bit expensive unless you already have a probe head for it.

At the machine we use Bryant Gages a lot, ID bore gages, and ID mics. On the cheap we'll occasionally use telescoping gauges & ID calipers with a mic when we can't get a size and have to check it now. You can get ID bore gages custom made for larger IDs.

Several manufacturers come to mind. Try Dyer, Dorsey, Mueller, Starrett; look for I.D groove gages and you will find various configurations. There is also a device usually named "Indicating groove caliper"; some of these have contact points that can vary the range.

Depending on the tolerances of the groove; if you would normally be able to measure with digital calipers, can you use something like: Groove Masters

I pulled the image from MSC, depending on where you live, you would have to order from someone else but....

As long as the supplier isn't your company, why not just post the name here?
