Overcut in deburr 3d chamfer

Recommended Posts

Anyone have any suggestions on getting rid of the overcut on this deburring cut?  

3 axis mill, .125 ball mill.  Currently using 3d chamfer, but I also tried 3d contour and playing with stock amounts., and a flowline for s##ts and giggles, but i couldn't get it to generate less than 3 passes per edge.

If you use surface finish project and use curves the amount of passes will equal the number of curves you draw.

I'd like to see which edge you used as a chain?

When doing a 3D chamfer I always use the inner top chain....

I got it very close with your method.  Maybe I just need to do some tweaking with parameters.  It creates a wide, but shallow chamfer.  It's uniform though.  Maybe I set it up wrong.  I made a copy of the solid, and created fillets, then used those faces for the machining geometry, then for the curves, I selected the geometry you see in the chain above.I think I just need to get it cutting on the right part of the tool now.

You can extend the surface if you need to, or draw an addition swept surface.

Looks good!

 

Nice to see the new toolpaths at work!

I don't see any way in 5x deburr to filter down the amount of code at all.  Am I limited to what I'm given?  I know the memory on this machine isn't the biggest.

Sorry dude, all the multiax liscences are checked out rn, I don't know that toolpath but I will check it later if I get the chance

Save the backplot geometry to a new level

delete the arc lead-in/out geometry and run a 3D contour path on the chains with filtering enabled

You probably won't get lines and arcs, but you should be able to reduce the file size by 50%

If you are doing multiple parts you could make this toolpath a sub routine so only one copy is required

It would be nice if the advanced 5X toolpaths could filter their output, but filtering 5X code can be very dangerous

The legacy 5x toolpaths have filters and you can get in deep trouble fast if you don't pay attention

Alright, I'll do that.  I'm getting new code like every .020"-.025", even in the same direction.  The motion is great, it's just kind of a waste for some of our older machines with limited memory.

I run into this all the time.

We've got some 80's vintage HBM's with 125K of useable memory.

This pretty much eliminates using toolpaths like this, or any of the high speed 2d/3d toolpaths

In your saved backplot geometry, you can delete the straight line segments and replace them

with one straight  line It's a little work and you have to be careful, but it's worth the trouble for a production file.

You can also try converting the curved segments to splines for your 3D contour path.

The filters might even give you arcs from those splines

With just saving the backplot geometry, and using arc filters, I was able to reduce the toolpath size to less than a third of the original.  Picked up 2 killer tricks in one day today.  THANKS!

I love what you did their with gcodes help rendering a lightweight 2d mill solution from a 5ax toolpath. Very elegant methods at play here.I am learning a lot as well!
