Hurco Post processor 2024

[AllFyve]

Hurco post processor from Fusion library.

Chamfer toolpath 3-operations, 

1-chamfer top of part

2-chamfer left side hole

3-chamfer right side hole

swivel head crashes into part.

Chamfer toolpath 2-operations,

2-chamfer left side hole

3-chamfer right side hole

swivel head doesn't crash into part.

From what I can see the crash only occurs when using 1 tool to do operations on multiple faces in this order. The approach after chamfering top of part always crashes into the part. Hope somebody can help.

Thanks Charles

Hi Charles,

thanks for your feedback! Have you actually tested the code on a machine?
If you look at the NC program in your first video, you will see that there is a G8.2 line that executes the Hurco ASR (Automatic Safe Repositioning) feature, so I doubt that a crash actually happens in reality, which would then mean that the simulation doesn't show the actual machine behavior in this case.

It would be very helpful if you could do a test on a real machine and ideally make a video of its movements.

[AllFyve]

Yes, I do have access. Hopefully I can report back today with a video. Thank you so much!

[AllFyve]

Update! I did run a test on a Hurco VMX 60 SRTI. It ran correctly as you suggested. I didn't get to make a video today but hopefully tomorrow. In the meanwhile, is there a possible solution for the simulation error?

[AchimN]

That sounds good, thanks for testing!
To properly fix the simulation problem, we'd need the video showing the machine movements along with the Fusion file.

[AllFyve]

Here is the machine video running the code produced by the first video in this thread. It doesn't crash into the part like the simulation shows. It also retracts to machine zero when indexing the C-axis which is a good bit with a 60" table. I have seen how to fix this if using the conversational control on the machine but not anything that is working for NC programming or the Fusion post. Hope you guys can help with this.

Thanks Charles

I tried to upload the fusion files, but it won't let me...says wrong file type. File type was .f3z

[AllFyve]

Tried sending the files again...still not letting me reply with the file attachment.

[AchimN]

Thanks a lot for the video, that is very helpful!
Its probably the easiest if you would just share the link to your file. To get that link, right click on your Fusion file and select "Share Link":

[AllFyve]

Try this...

Hope this helps!

[AchimN]

Excellent, that worked, thanks Charles!

We will look into the post and try to get that issue fixed ASAP.
I'll keep you posted.

Thanks again!

[AllFyve]

Just wanted to check back with you on this. Just wasn't sure what to expect on potential solutions. 

Thanks Charles

[AchimN]

Hi Charles,

I think I found the problem, its fixed in the attached post.
Can you please give it a try and provide feedback?
Thanks!

[AllFyve]

Hi AchimN, 

Here is a new video with the updated post processor you attached using M140. The simulation doesn't simulate the M140, it should be retracting to machine zero in X like in the video. The lack of a G53 Z0 at the end of the program is causing the spindle to approach the table, not sure why. The first video of the actual machine movement I sent must have been posted without a M140. It's the only way it would've ran like that, my apologies! I really appreciate your help, understanding just how the HURCO Intelligent Automatic Safe Repositioning works has been bit of a challenge for me. 

[AchimN]

Thanks a lot for your feedback @AllFyve !!

Yes it seems that your initial video was made without the M140 option being active.
In the attached post the M140 move should now also be simulated properly. In addition, I´ve modified the post to output G53 Zxx right after the M140 since i think it is needed in order to be into a safe position when indexing the rotaries.

Any feedback is very welcome 🙂

Thanks!

[AllFyve]

Hi AchimN,

The simulation and actual machine movements are now in tune...awesome! Thank you very much for this. It would be nice if the post properties had the option to add an L token with input for desired value to the M140 as well as the G08.2 that is added when G68.2 is selected in the post properties.  As it stands you must edit the posted program from Fusion if you wish to have any control over the approaches and retracts being the G08.2 disables the Hurco Intelligent ASR. Here is a video showing the hurco_01.cps post using the L tokens along with the code for the operations we have been using. Also, using anything greater than M140 L0.0 at the beginning of the program will cause a Z axis over travel. 

Thanks for all your help AchimN!!!

Charles

Excellent, thanks for all your feedback and for providing the videos of the machine movements, that was very helpful!

I will go ahead then and update the library post.

Regarding the "L" option for the G08.2 ASR cycle, it should be no problem to make this a property into the post for the NC output, but I am afraid that machine simulation cannot handle this special case at the moment. 

[AllFyve]

Will the "L" option be added for the M140 as well?

Thanks AchimN

Charles
