Thread turning cycle spring pass

patrik_stellgren — Thu, 22 Oct 2020 12:57:25 GMT

Hi,

I'm editing a post for my lathe and kind of got stuck.

I have tried a few different turning posts but most of them does not support "Springpass" when using the cycle.

The only post i found it to be working in is the Generic Haas turning post. I've looked in to it but can't really wrap my head around it.

The problem is my post doesn't generate a spring pass when using threading cycle. The dump shows two passes at the same X value. But not the posted code.

My guess is to use the isLastCyclePoint() function but not sure what to write in it.

Hi @patrik_stellgren ,

What control and cycle are you using?

Thanks,

Will

Been tinkering a bit and might actually have solved it. Probably not the best way and it might cause other problems further down. But it works for now.

I created a variable for the parameter nullpass and a if statement using isLastCyclePoint & the created var

Looks like this.

Feel free to give input

if (hasParameter("operation:nullPass")) { var NullPass = getParameter("operation:nullPass") } if (isLastCyclePoint() && (NullPass == 1)) { writeBlock( xOutput.reset(), xOutput.format(x - cycle.incrementalX) ); } return;

Hi @will_1

It's a Seicos L multi 🤣 based on a yasnax LX 3 back end. G92 threading cycle modified for my control.

Thanks

Hi @patrik_stellgren

That makes sense to me. If functionality for the number of spring passes gets added it probably wouldn't work with that.

Thanks,

Will

Hi @will_1

Is there a way to select the number of spring passes in fusion? I don't see any such option?

Thanks

Hi @patrik_stellgren

There is not a way to select the number, but if it did get added down the line then the logic in your post processor would only do the one spring pass which isn't so bad. Not anything to worry about.

Thanks,

Will
