generic Hurco 5-Axis post

[KerimY]

We are working on a generic Hurco 5-Axis post processor and we would be happy to get some feedback from you before we put it into the library.

This post is only to test the 3+2 and 5 axis. It will be implemented in the generic Hurco post if its done.

Update:

• add properties for the safe tool change position in X and Y

Please feel free to download and test it:

hurco beta.cps

[MJK_Performance]

YES! I will try this out today. I have a few sample programs from hurco for 3+2 and 5 axis for reference if you need them.

FYI - I downloaded and tried this and looks like my problems mentioned in another thread may be fixed. I will more carefully review the generated code ASAP and maybe even run it on my machine. 

[jerry426]

After more time with this beta (and breaking a 1/8 ball mill because I missed an error in the generated code before I pushed the pretty green button) I have this problem:

I have a Parallel operation which should happen at the indexed position of A-30 C135. The HSM UI clearly shows me that A-30 C135 is the orientation it will use, which is exactly what I expected to happen, however the generated code is A-30 C225 (see code snippet below).  

Is there something in the CPS file I should change to fix this? or something in the HSM GUI?

@KerimY can you look at @jerry426 problem?

[jerry426]

I can also confirm this happens on a Pencil operation which should be indexed to A-90 C150 but the posted code output is A-90 C210:

It is weird because the output but then negative would be correct.

So I'm not sure why that is wrong.

[AchimN]

@jerry426 could you please share your programmed part so that we can take a look?

[jerry426]

@AchimN My part assembly along with the part model and the stock model and my slightly modified "hurco beta.cps" file are here: 

https://www.dropbox.com/sh/bp3s8kz7lbfi9bp/AAA1M_k5g_likU_tKgTqfs85a?dl=0

The operations in question are the last 2:

• "Side Rail Undercut"
• "Tip Corner Cleanup"

I am running HSMWorks 2016 R3.40968

I ran this last night and have a couple of things, 

for the trunnion style hurcos it would be nice to have a safe tool change position:

N33 G0 M140
(2D Adaptive1)
N34 M9
N35 M1
N36 G53 X0. Y0. (<---- safe tool change position)
N37 T6 M6
N38 S12000 M3
N39 G54

and it need to unlock the "A" and "C" axis before doing 5 axis simultaneous tool paths;

@jerry426

Hello Jerry,

You activate the machine angles in the post which is deactivated by default.

You use the Machine Configuration in HSM to see the angles in the simulation, you have to adjust your Machine Configuration in HSM to your parameters in the postprocessor otherwise the angles in the simulation are wrong.

Please update all parameters in the page "Rotary Axes" in 4th and 5th axis with the same parameter as in the postprocessor.

.


Please update your postprocessor with the correct parameters in the MachineConfiguration.

@MJK_Performance

Hi Phil,

i updated the postprocessor in my first post and add 2 properties for the safe Tool Change position in X and Y.

Unlock axis works only with machineConfiguration because the postprocessor dont know which axis your machine has.

It is possible or an error if i unlock all axis (M33 M35 M13)?

Thank you all for feedback.

[jerry426]

@KerimY 

I made the adjustments you suggested and it now looks like I have good usable code being generated - THANKS! I will test it on my machine later this evening and hopefully report back here with confirmation that it works correctly. I also updated all my files related to this in my dropbox folder if anyone was curious to have a look at it - https://www.dropbox.com/sh/bp3s8kz7lbfi9bp/AAA1M_k5g_likU_tKgTqfs85a?dl=0

[jerry426]

I am happy to report that my latest attempt, based on the suggestions posted in this idea, has produced running code which I am now using to make parts (all 3+2 stuff). I added a few more personal preferences to the CPS file such as forcing the home position to be where I want it and other very minor things.

I hope to have time soon to check out the full 5-axis features.

Thanks to everyone that helped!

[KerimY]

sounds good.

Can you guys test the post without machineConfiguration, with Vector output?

You must deactivate the machineConfiguration in post and delete your Machine in HSM so it works.

[MJK_Performance]

Ill try that as soon as i can

[MJK_Performance]

I have vector output running smoothly on the machine

[Laurens-3DTechDraw]

 @MJK_Performance awesome that you tested this.

I have nothing the do with the development or need for the post.

Just wanted to say thank you for that.

[KerimY]

@MJK_Performance a big thanks from me too.

I implemented this in the generic hurco post and update it in the post library soon.

I need to add a setting in the post to lock/unlock axis if you use vector output.

@Laurens-3DTechDraw thank you.

[MJK_Performance]

Just noticed a thing. If you are using multiple work offsets on different faces (like on a tombstone) it will only call up a G68 and G8.2 for the original work offset and not for the second one, which causes an error.

Hello @MJK_Performance,

can you send me your CAD files please.

Moving to "under review" in advance of separating out the post ideas from the general software requests. This was a batch process. So, this particular idea may still be archived.
