Turning - confine radial grooving

[genxmachining.mill]

I am attempting to turn a part with various shallow undercuts and some o-ring glands. In the passes tab, I can enable radial grooving but it also plunges for my o-ring grooves. How do I allow it to turn the undercuts but not the o-ring glands?

Of the top of my head, I think you can make a sketch of part sectional profile to bypass O-ring groove, select Model in geometry tab and select sketch as driving geometry for cut.

On the other hand turning radial grooving on only allows profiling tool to remove part of the stock from undercuts and you have to come back with grooving tool anyway so there is no real benefit in doing so.

@Anonymousthank you for your reply. I will give that a try!

As for the undercuts, they are quite shallow so the turning tool does an adequate job of profiling those areas, but will be using a grooving tool for the o-ring glands. We have drawn them up in a way that the back clearance angle is less than that of the tool.

Sketch used to work to define cutting geometry but now it doesn't, the alternative is to duplicate setup and model, edit model leaving only desired features in it and use that model in setup to produce finish pass then combine posted code.

This would make sense if there were multiple grooves to be avoided while including others but for single groove I would just edit G-code in NC editor.

@Anonymous when selecting the chain, it appear you have to do the ALT select and add on to the chain:

And, just to add, the devs are aware of the need for groove suppression 😉

Nothing further to share at this point, but it's on the list...

@seth.madore , So you are right about hitting plus sign, for the OP ..... after selecting desired sketch, click on selection second time, it turns red, hit plus sign in small window that pops up.

Now, I may be slipping but I am pretty sure that wasn't the case in the past for turning.

I know I have to do that when skipping selected edges on mill contour, to connect it into one chain but this was news to me, thanks. 😊

You can also just select the whole revolve sketch profile, either from the display or the Browser menu

@genxmachining.mill Like Seth said, we are actively working on a more flexible way to suppress individual grooves and we should be able to release this feature soon.
