Initial Work Offset Posting Twice (Multiple WCS)

[Anonymous]

Hello there,

When I post multiple WCS over more than one setup at the same time, it will run through all the WCS in the setup in sequence in whatever way I specify (preserve order, order by op.....) and then it will run the first WCS in that setup again, in full preserved order, before moving to the next setup, where it does exactly the same thing.

For example,

Setup1 runs at G54 and G55 (in preserve order to keep it simple).

Setup2 runs at G56 and G57 (again in preserve order).

If I select both setups at the same time and post it out, it runs as follows: G54, G55, G54, G56, G57, G56. I think I had the same issue with the reorder to minimise tool changes box checked too. 

If I post the setups individually they post out as expected. The issue exists using the Mazak post I've modified and a test done with the generic Haas too.

Is anyone else experiencing this issue? Any ideas what the problem could be?

Thanks,

Dave

which software and can you put the files up?

[Anonymous]

Sorry, Inventor HSM.

The issue persists across three different part files that I tried at random, one of my posts and the generic Haas post.

I can put up some files on Monday, but I was wondering if anyone else was experiencing the same issue, or maybe someone could replicate it?

Hi Dave and Len, I am using HSM for SolidWorks If the initial WCS is 1 in the second setup I would get the results you described. As you can see in the photo the initial WCS is 3 and then it posts out starting at G56 and then goes to G57.

I don't use that function, I copy the job and put a different offset and then order them in the tree, then select and post the ones I want.

that way I can post 1, 2 or all 4 or any combo.

did you try the first field at 2? instead of 3?

[Anonymous]

After another look what I was thinking wouldn't get the results he was getting. 

I will try separate jobs with different offsets.

If the first field was 2 it would start at G55.

Setup1 - The work offset field is 1. Multiple WCS offsets is checked and number of instances set to 2 for G54 and G55.

Setup3 - The work offset field is 3 and multiple WCS set as above for G56 and G57.

I can post either setup individually and they run as expected (the toolpath is executed at each offset once), but if I select both setups at once I get the issue described above.

can you do a screen cast of whats happening?

what version of SW and HSMWorks are you using?

Hey Len,

I'm using the current release version of Inventor HSM Ultimate.

I've put together a simple part to show the behaviour without the posted code being too long. This uses 3 WCS on each of the 2 setups. IAll of the posted files use the stock Autodesk generic Fanuc post processor nothing modified at all.

PreserveOrder.nc goes through G54, G55 and G56 as it should from Setup1, but then runs G54 again before moving to Setup2 then running G57, G58, G59, then G57 again.

OrderByOp.nc runs through each operation at all WCS on Setup1 as it should, before running through the whole thing again at the first WCS, then moving on and doing the same on Setup2.

ReorderToMinTC.nc exhibits the same kind of behaviour. Working through all Ops and WCS correctly, before running the first WCS of each setup again. In this case G54 and G57 reordered to minimise tool changes.

I can post either Setup1 or Setup2 individually without issue.

And here is the last attachment.

Dave sounds like an inventor issue, sorry but I do not use inventor only SW and HSMWorks

one of the other guys that use Inventor will have to sort this out.

[Anonymous]

Thanks for looking anyway.

Dave,

If I'm reading this correctly.

If you are posting operations from two different job setups regardless of the Multiple WCS usage, the operations will sequenced as such. The preserve order will only apply in its respective job setup.

Len have you ever tried posting operations from two or more job setups that are defined using multiple WCS in each? Form the way I read Dave's initial post the system is behaving as I would expect it to.

[lenny_1962]

@keith_clausen 

no I do not, I've only really used it twice in HSMWorks since 2012.

If I have multiple work offsets I just copy and paste the job folders in the tree and change the offset numbers and the output post name that includes the offset #.

Yes I know Keith it is not optimized, just how I like to do it, it's just so friken easy if you protect all the ops, I can pick and choose and reorder the tree to have it post out what I want to cut first, second.... 15th. And I always program in the assembly because I use a sh!tload of configurations and display states to manage during programming.

just doesn't sound correct to me that it recuts the fist offset...???!!! 

[keith_clausen]

Yes, I was speed reading through the initial post....my bad!

@Anonymous I have your file open and I will take a look at the posted code.

[keith_clausen]

@Anonymous

From your file I posted both setups using the Generic Haas post (Pre-NGC) and it seemed to post just fine, I even selected "Reorder to minimize tool Changes" and that to worked fine. If this is not working correctly for you It could be the fact that it is the  version of HSM you are using but more than likely it is your post processor that needs updating or tweek.

What version of HSM are you currently using?

Can you upload your post processor? If it is a generic post included in the install, please state.

I ran through Dave's file and posted it different ways using the Hass (pre-NGC) post and all seems as it should be. My guess is that his post is possibly out of date, may have hard coding for the WCS management and or a WCS reset in the post that is preventing the code from posting correctly.

[Anonymous]

Hi Keith,

Thanks for looking into this for me.
I first discovered my issue with a Mazak post that I modified from the Autodesk generic Mazak.cps . I then tried posting with the generic Haas to try and narrow it down to an issue with my PP, but the issue was still there.

My example problem code was posted using the Autodesk generic Fanuc.cps.

As far as I know we are updated to the latest release version of Inventor HSM and the generic posts were selected by me at random from HSM’s generic posts folder (which would be updated with any updates of Inventor, correct?)

I’m on U.K time, so I’ll put up the Mazak post I’m using up for you when I get into work tomorrow.

Thanks again
