Gage Correction Qualification: Active/Not Active


---
 Share

Recommended Posts

How do I determine which features require "Gage Correction Qualification" (GCQ) when it is active prior to run time?
I know a program will fail to measure a feature that requires a GCQ, so that's the hard way.

Not sure I understand what you're asking ,If it's active prior to run, then that's already preset, right?

It shouldn't be difficult to explain but, it can be depending on how you use it.

To set a feature needing gauge correction, you open up the evaluation tab and select "gage correction" but, it must have a feature within the program to measure the gauge at a set location relative to the base alignment prior to running that feature - or- the gauge qualification was run with a separate program prior to running for the probe being used.

I used to have a program where I set a ring gauge in a designated location beside the part being measured, I used a little make-shift fixture to locate the ring gauge off of the part so it would always be in that location and then I would run the gauge qualification feature in the program before running the features that required the correction.
Clear as mud right?...probably not but we're all limited with time on this forum.

Attached is an instruction document that may help. 164_2eec44ee28b614ce59ce821c573e0f24.doc

Thank you Owen.
I am trying to figure out how I know a program uses GCQ.
If an operator starts a program and it requires GCQ, it will fail measuring features. Our second shift is the concern, they do not have the experience to edit programs.

I see.
I always put it in the measurement plan comment/instructions that is shown in the run menu and then also put a comment with PCM in the presettings to tell the operator to not forget that the probe needs the gauge qualification run before running the program.
You could also put a program stop in the first feature (if you're running off features) to inform the operator.
However, because I put it in the program (not a separate program) I don't remember it ever not measuring a feature. That's been a few versions ago, so they could've changed it.
I used it specifically on a disk probe.

Just had this issue with Disc stylus. I was able to change the limits for that stylus only and prevent this. My problem was the Sigma was above my global threshold, as it is a manual qualification.

Sorry to hijack this conversation but does anyone know if Gage Correction corrects the X and Y, too? I've always assumed it did not and have leaned towards using manual corrections using data collected in the ring gage program.

In my case it did not have an appreciable effect on them. I have two features in my qualification program. One is the gage correction qualification, the other is an identical circle with gage correction selected in evaluation. It corrects diameter , but didn't seem to affect location. This is my first use , and the deviation is around .0000X " and is not a problem in my application.

When I've used this puppy, it didn't seem to affect the position accuracy, maybe 0.002mm.
I always check the same front and back bore features on the ends with a much shorter standard 4mm probes and compared them with what the disk obtained. 164_2b8f8e084c6fb3f99f3db95021f19a70.jpg
