Hi Friends,

If you find a bug or have a workaround in V5R22 SP-xx, please put it here.

Please be sure to state the Service pack also

The intent here is so all the COE members can do the following.

  • Have visibility of what is ahead so they can decide to upgrade
  • If they do choose to upgrade, they will have advance knowledge of known issues.
  • We can help each other, with workarounds

Thanks

Dave

Oh, and Let’s try to keep these Bug Bulletin Boards clean, and Hijack free, so the information is easy to read.

V5R22 SP0

Tricoidal milling aplied the inverse of the desired offset.

If you entered a .25 offset it would apply a -.25 offset and vice versa.

SP4 cured this problem.

Thanks bud.

If we all work together as a team,  we can kill this monster.

Monster = unknowns

Hijack / off, continue

Reported by one of our users in CATIA V5R22sp4:

When editing or creating a tool axis, the tool axis function is not working properly (or at least how it has worked in previous revisions of catia V5).

If I wanted to change or reverse this tool axis I would do the following:

1. Select tool axis

2. Select a surface or feature to set desired tool axis

3. In this case I reversed the current axis.

Graphically nothing happens. Before the orange arrow would reverse giving me instant conformation of results. Now I don’t know if I have the desired results.

To see the results I have to close out all of the dialog boxes. If results are not as desired this new problem creates a minimum of 5 additional steps to redo!

Anybody know of a solution to this?

Hmmm.

We are running V5R22 SP4.

I tried to duplicate your problem, but it seems to be working fine here.

We created a "Point to Point" operation just like you showed.

The vector display behavior was correct in every way, in every scenario we tried.

It's not that I don't believe you. What is missing is what set of unknown circumstances would cause this to happen.

V5R22 SP4

We are finding that if we edit programs created in older versions of Catia, the tool axis will invert.

The toolpath and operations are fine until you edit them.

We have observed this behavior in axial, profile contouring and multi-axis flank operations.

Now if we modify an operation, and it doesn't compute, we check the tool axis first.

Hi Randy,

Thanks for posting this. I will see what I can find out as far as if Dassault knows about this, and also... if it has been fixed, and at what version / sp level

Macro limitation for thread milling approach/retract?
(in response to Dave Frank)

Hello,  A customer is having a problem...Is there a way for the approach/retract circular macro to follow the thread pitch?  Helix isn't available, just a circular motion; changing the Angular Orientation isn't working well enough, the Apr/Ret are still gouging the threads because the circular motion is horizontal, not following the pitch of the thread.

A helical move would be good (I think), but I fear the customer may have to change tooling or redesign the internal thread (by undercutting the thread?) in this .500in dia x .500 deep hole.

Anyone else have this issue?  Is there a way to change the circular move to follow the thread and not gouge?  

**EDIT** I believe the answer is to select Optimized Pass in the Machining Strategy pulldown.

[External] Macro limitation for thread milling approach/retract?
(in response to Paul Guariento)
Are you feeding from the bottom up and using a multi flute thread mill? You could switch to a single point thread mill. Other than that if you arc into the thread at the bottom with a multi-flute thread mill at a fixed Z level all of the initial cuts will be the pitch apart so when you start helix motion up the cutter will engage the initial in feed marks and clean them up. The end of the arc needs to finish on center so your approach down the hole needs to be off center at the point of the start radius.

Thanks,

What Version are you using.  I thought they fixed this at some point to follow.
