[Post Processor, Heidenhain] Cycl call after coolant off

[mbl_busse]

Hey there folks,

I want to optimize the pp for our C52 a bit further.

Before a toolchange happens I want to 'clean' the remaining coolant from the coolant-jets or the tool by blowing it out with air.

With normal flood coolant this is no problem- Hermle added a M-Code wich does exactly this (M440).

But for through-tool coolant there is only a cycle: cycle 315.

Therefore I have to add a cycl def after setting throughTool coolant off.

It has to look like this:

CYCL DEF 315 IKZ WZ ausblasen
Q1505=+2 ;Zeit ausblasen

Does anyone know how I could achieve this?

line from my pp, M440 already added, works flawless:

var coolants = [
{id: COOLANT_FLOOD, on: 8, off: [9, 440]},
{id: COOLANT_THROUGH_TOOL, on: 51, off: 52},
{id: COOLANT_AIR, on: 7, off: 9},
{id: COOLANT_AIR_THROUGH_TOOL, on: 12, off: 9},
{id: COOLANT_OFF, off: 9}
];

Thanks in advance and stay safe!

Hi,

something like this will do the job.

Thanks,

Hey there Jacob,

this is quite a good start, thank you very much.

So I got it working on pgm-end by writing it like this:

But this code doesnt work in case of a toolchange. I think the problem here might be that the currentCoolandMode is set earlier. Is there a way to 'grab' the coolant wich is currently running? In this case he seems to already take the coolandMode from the next tool..

Hi,

Do the same in OnSection.

Thanks,

Jacob

Thats exactly the line I've inserted the code.. It's still the same thing.

If I go like you stated

[if (COOLANT_THROUGH_TOOL)]

the command will be executed with every toolchange- independent of the actual coolant.

If I go like

[if currentCoolantMode == COOLANT_THROUGH_TOOL]

the code will show if the NEXT tool hast TroughToolCoolant.

I attached my post, if you want to take a look..

Hi,

Yes sorry, you need this condition.

Thanks,

Hi Jacob,

thanks for all your help, but I just cant get this to work. Even not with the PP from your last post..

I tried several iterations of this code. I'm sure it's just a small thing, but something is missing here.

Hi,

Will you share a project where you have the fail?

Thanks,

[mbl_busse]

Sure thing! It's just a file I tinker around for different ToolChange-Scenarios, because the NC-Extension of VisualStudio has no setting for something like M51-Toolchange-M8-Toolchange-M51 etc.

Here you go.

I also attached the NC-Program I get when PPing this through your PostProcessor. (changed to .txt for upload)

Hi,

Now I thing it works:-)

Thanks,

Jacob

Ha, Jacob!

This seems to work. Very nice! Thank you very much. This was infact quite educational 🙂

One small issue seems to be, that now the cycl is also added to the first tool call. But thats really just a minor issue.

Thank your very much! 🙂
