I am having an issue once in a while with hole diameters. I am using a 1mm ball to check the the part. This issue comes and go's. I ran a program this morning with true positions and hole diameters and everything checked out. A couple of hours later I ran the same program on a new part and I was getting the hole diameters .004 to .005 big(which they were not after verifying them). The nominal for the hole diameters are .050 +.002 -.000 inches.So i went back and ran the same part from this morning(that was good) and now got the hole diameters out. I tried requalifying multiple times and tried shutting down the machine. I even tried changing out the probe tips. After changing the probe tip to a .5mm ball I am now getting a different hole diameter but it is now showing the true positions out. Just wondering why I would get two different readings with two different probe tips and why the same part would not repeat from this morning until now?
I think i solved the problem. With the hole diameter being so small I started to play around with the prehit/retract distance. Finally I changed the touch speed and it solved the problem. I was at the recommended touch speed. But I still had to go lower.
