Gouge check is not equal to collision check?

[kukelyk]

I have some cavity mill toolpaths. Some of them generated with the setting 'Check tool and holder' OFF. So there are some toolholder collisions. No problem. If I ask for the shortest tool length, it gives correct value. With the short tool (shorter than the reported one), I made a gouge check (The window title: Gouge and collision check) with the option 'Check tool and holder' switched ON.
The appalling result:
Gouge check does not support non-uniform stock. Only one stock value will be used.
Stock used:0.5
No gouged motions found.

Is it in NX 8.5.0.23.
How should I check my paths?
Fortunately it is only a test license..

No one wants to address the problem.

Thanks, I had that, but my question is not for cavity mill. My problem is the Gouge check reliability..

Are you noticing gouging in other types of operations, or has it been just Cavity Mill?

As I mentioned above, the path is calculated with the setting 'Check tool and holder' OFF, so it could be any other operation type..

Are you using custom stock or offset on the geometry?

There are different part stock and the floor stock, and an other different value for check stock. The check geometry is one face of the workpiece part.
I use no methods, the stock inside the workpiece is 0.

Sorry, kukelyk, you said you "...have some cavity mill toolpaths.......How should I check my paths?..."

Are you talking about just cavity mill paths, or do you have other types of operations that violate and gouge the part?

Does the type of operation makes any difference at Gouge checking?

Yes. The type of operation matters here. There is a history of the cavity mill operation violating the part and gouging. I am asking if you or anyone else sees this gouging on other types of operations, also.

We need an answer to

1) if other operations gouge, which ones, and why,

and

2) why gouge checking does not recognize gouges.

Hi,

I have used Sequential-Mill in UG when Catia was failing to produce the tool-motion. However, I noticed that UG didn't detect the gouge using Gouge Checking. And I found those gouges after I imported the cl file inside Catia. This was at my last job over 4 years ago. So I don't know if this is still the same.

Regards.
