Cylinder Measurment

[italianm28]

cylinder only measureing 1/2 of the Dia in the correct work plane and in automode. Any help

Could you post the portion of the code with the cylinder and some before it? The only things I could think of off hand is if you had radius selected in output(not likely, but possible), if vector of cylinder came out wrong, or maybe if a small cylinder if the probe comp was off or wrong. These are just wild guesses without seeing the code and resultant output.

Jeff. Thanks for the reply. It's weird I measure 5 more cylinders on the Parts I'm validating and they all work fine in prog mode except the 12_3_cyl
Looking forward to finding out what's the deal.

The only thing I can think of is that you're stylus may not be lined up with the cylinder. Virtual DMIS will try to avoid hitting the shank of the stylus if it's not straight in line with a hole. This will cause it to only measure one side of the cylinder. If you're sure it won't shank, your best bet would be to use prog mode instead of auto.

Sorry for the late reply. There isn't much activity on this forum so I don't check very often.
