On machine probing, COE Members only discussion for future requirements.

There's a very lively discussion on the topic of on machine probing in the open forum.

http://www.coe.org/p/fo/st/thread=26749



This is a very important topic. I think it's great that everyone is sharing all the workarounds ideas and tips and tricks.... but at the end of the day I think we all gotta start thinking about what we need from Dassault systems, so that we can get some have the box solution.

I wish I could say that I was doing this myself but I'm not. But most certainly people have tried this using Catia, and whether it was limited  training or limitations of the software.... whatever the reason they didn't get to required result.

I think for the most part the point of on machine probing is to do best fitting and some location using fixture offsets or some other compensation.

The idea of the cold members only forum is to have Frank discussions of the limitations and flaws of the software without having the competition looking at the discussion and using it against our friends.

So what I think is required hear some actual intelligence. Something that the coe dpc chairman can look at and come up with some requirements, so we can have a new usable tool to have at our disposal.

Now where I can help is with my icam expertise is to talk about what the post processor is capable of doing.

I hope to hear from someone you soon
Best regards

The power of probing comes with using the data that the probe stores in the control.  Just positioning the probe in the right place is less than half the battle in my opinion.

I would love to see CATIA be able to access the data from the control and do math and make decisions based on that data.

Using the current machine control technology, I imagine that CATIA would have to write subroutines to the control in the control macro programming language.  Or maybe CATIA could control the Renishaw subroutines.  But the program also needs to access the stored data in order to make use of that data.

The only way I know of to do that comes with reading and writing to the control data registers.

I would love to see easier control of probes and probe data

Hi Dave,

I have a Catia V5 R21 SP6 Probing issues document I put together with screen shots in it. I couldn't get it to copy the screen shots into this editor. Would it be okay to send this to you for review?

Hi Roger,

We are in the early stages of using Catia's Probing MO's. I have my post outputting Renishaw Inspection Plus Cycles for the 840D driven by Catia's Probing MO's aptsource output. All Rapid moves are output in the renishaw protected positioning mode if the probe is turned on. I made Post commands for such things as turning the probe on/off, controling the report file, etc. For any manipulation of the probed data we use the pp-instructions inside the appoach/retract/linking macro's.
