That's the email I got upon entering the shop today. I was using a 1 x 10 styli for a part with 3-48 & 6-32 threaded holes. Just trying to get a decent location within tolerance of +/- .005. Now, the customer (we are the sub-contractor) is "coming in today with a cylindrical probe which will take more accurate hits on thread holes". I checked some of the postings in the forum and it looks like there's a lot involved and the results are sketchy.
PC-DMIS has the possibility to measure circles and cylinders with a pitch - going up in a spiral, following the thread. This means that you hit the thread in the same way all the way around. This is in most cases better than using a cylindrical probe tip. Unless the pitch is wrong...
