Formula

[[Me...]]

To all the smart formula creators,
I'm looking for a formula to insert in the feature strategy.
The feature is a cylinder and I want the formula to evaluate the 'form' of the feature. If the 'form' is greater than .0006", I want the program to pause (or stop) and instruct the operator to clean the part and re-start the program.
Make it so...

Do you run from the feature list or the characteristic list?

Features list. Also just installed Calypso 2018 about 3 weeks ago.

If you have the a license for PCM then you can put the following in the post settings for the feature that you wish to check the form of.

This is based on the form characteristic being named "Form1" and the tolerance for Form1 being set to 0.0006

You could also put in the value 0.0006 if that is not the overall tolerance of your form characteristic.

If you don't have PCM i'm not sure what you would need to do to accomplish what you are trying to do.

if  getActual("Form1").actual > getNominal("Form1").tolerance.upperTolerance

	message("Form1 exceeds allowable tolerance. Please clean the part and restart the program.")
	cncBreak()

endif

Thanks Derek! I'll give it a try.

In 2011 they put the Warning limits for manual run's in the Measurement Plan Editor for features so,if you're doing a manual alignment and have bad probings and the feature being checked has bad form (worse than you specify) then the CMM stops and pops up a message window like below.

I know it was 2011 because it was presented at the last national user conference in Scottsdale Arizona and I asked them if they could make it that simple to put into CNC runs too. Didn't sound like an irrational request to me but, it was 7 years ago, it must not have been that important to them..lol

Yes, you can do it with characteristics if you run off of them, yes you can use PCM if you got the $.

You can put a condition in the feature's strategy and have it check it again but, you can't stop the CMM, not without PCM.

I remember that Users Group Conference. I was given the job to sit at a desk while customers waited in line, waiting for their turn to stump the Apps Guy. My boss came up that idea, and it went pretty well as I remember. There was also the end of the day shot of tequila on the terrace.
