Hello,

I would like to help in choosing the best finishing strategy in the channel of this attached piece, I am trying to do it on the surface, without success, you could help me, it will be of great value, thank you.

I think if you can get a centerline down that channel and unwrap, a wrapped groove might be your best bet. If you want to take multiple passes, you could play with your surfaces and go for an isoline using to-line potentially as well.

Thankfully, one of my colleagues who is far wiser (read: older) than I, just messaged me to inform me that I don't know what I'm talking about and missed that you have a tapered surface there. A groove is definitely not the move unless you have perfect form tools for your profiles and you just want wrapped single passes....which probably isn't the case. 

 

It looks like you're going the surface milling route looking at your other features. For the long tapered bit, I think isoline is perfect. Make sure to grab a small tool, as it looks like you are currently trying to use a 12 mm BEM which is far too large.

 

The blending point between the long tapered surface and the small bottom-radius-style portion may be a bit tricky, especially considering how tiny those bottom radii are. How you program that is really going to depend on how you want to approach it. I could see a few things working... you could potentially go down the route of trying to extract, offset, and unwrap curves, and go for a side finish-pass bottom-radius type of situation, although that is going to require some considerable precision on your part with the profile curves. Isoline may be one of your better options for that portion, although it has the downside of only machining each surface individually at a time. For the top flat, this will work fine but could make blending the various faces together difficult. If you can get a single surface from those, I think that option could work fine. You could certainly get tricky with reference and guide surface-creation and make swarf work, but that option is above my cad skills. I tried pencil hoping that might work nicely, but no dice. 

 

I don't think there is an easy bolt-on solution for getting all those small faces in one go. I always try to make isoline work, but as always, there are many roads to Dublin in this case. Hopefully, this gets you pointed in a direction that works for you. Keep experimenting till you get the final result you're looking for.

I think a surface mill feature is your best bet, however, you are limited.

 

Take a look at the attached project.  I chose a Flowline strategy with a reference surface.  The only downside is I created the surface quickly in PowerShape.  You may be able to do it directly in FeatureCAM, but I think you may run into snags.....depending on the aesthetics of the surface you need.

 

Since there are undercuts here, you are limited to strategies you can use.

Hello,

Thank you very much for the solution, for the example of interaction in this scenario.

Hello,

Thank you very much for the considerations, all of them were great for the development, knowing more about the behavior of each strategy, 4 axes that I am learning for each piece, for each program, thank you very much.

 

God bless you
