nested containment

[k turk]

i read some older threads about this error, but while the answer may be the same, my application seemed slightly different. using the latest greatest X2-MR2.

 

the model:

imagine a simple flying saucer shape - ie. a gently sloping dome with a hole in the center.

 

the toolpath:

surface finish contour with containment set at the outside perimeter of the saucer and a boundary offset close to the inner hole - ie. nested containment circles. i want to avoid the central hole area.

 

the error:

Boundaries may not intersect, overlap, collapse, or be nested for Z machining(try analyze/chain)

 

can you really not have a nested containment? using the same containments i am able to do this with surface parallel, but i would prefer to use finish contour.

 

thanks

No, you cannot. Not on Surface Finish Contour. You CAN however have nested containment on HSM Waterline toolpaths.

Another alternative would be to create a surface to cover the hole and call it a Check surface and use only the outer containment boundary

[k turk]

that worked well; although for whatever reason, took a long time to crunch.

 

radial toolpath also worked.

 

thanks

okay, similar situation but with a different model and the toolpath is now a surface rough pocket.

 

same error - Boundaries may not intersect, overlap, collapse, or be nested for Z machining(try analyze/chain)

 

if you can't nest containment boundaries, is there a way to pick one boundary and have it cut everything outside that boundary? i could use the check surface trick, but this means i have to spend time generating surfaces. this strikes me as a big gap in MC's capabilities . . . is it just me?

Seems like your "Gap Settings" could handle that. Set it bigger than the hole and it should stay out of it. Not sure though.

Same answer as above!

 

Build a flat boundary surface over the area you don't want to cut, higher that your top cut and use it as a Drive Surf. Or use HSM Area Clear.

thank you. i will accept that i will have to create more geometry in such cases. it isn't that much of a problem as the boundary curves are already there. i will also have to look into HSM toolpaths - not familiar with them.

Once I tried the HSM toolpaths, I havent used a Surface toolpath since.

Go with HSM toolpaths. Nested bounderies is just ONE of the improvements.

WOW!

 

a whole world i didn't even know existed
