toolpath idea

[mirek1017]

what 5 axis toolpath I can use for mill this windows ,something like 2d ramping around the contour

None I would use 2D ramp with planes as each index. I like the fact I can set a start and end position that will be above the highest place and below the lowest. With a 5 Axis toolpath we have the extend feature, but no need to over complicate things when it is not needed.

when I am unroll the curve what  angle I should tape 

 

 

 

 

 

 

 

 

 

 

 

I unroll the top edge 0 and  90 deg   and I cant  properly fit in my solid window

Okay that is a completely different things that what i was seeing when looking at the picture. That is a full 4 axis operation not a 3 axis operation since the wall is not normal to a plane. Then yes a 5 axis operation would be good here. A couple different ways, but I would cheat here. I would make a dumbed down solid with floors and then use pocketing. How would could a programmer go about that process with a part like this? (BTW notice you get a lot of help. That is because you share a file!!!!!!!!!!!!!!!!!!!)

We use Model Prep and make a solid from the pockets with create verses remove. Then use Wall Finishing method and Cutting Method Spiral and I think it will be what you are looking for.

We could think about other ways, but this should be a good start.

Thank you Ron

if you dont have multi axis you could use rollidie

its a bit wonky as you cannot really change parameters, it doenst regen correctly and it doesnt have lead in/out either

if you want to make changes do the toolpath again

its a chook

we do have 5 axis I want to find out what option will be the best 

 

thank you for your sample file

haw  I can fix this ?

I noticed that files has two different types of pockets in it. Which ones are you trying to machine? 2 of them have sets of walls normal to the center line and 2 of them are what I would call true 4 axis pockets. I could machine the ones showing there in a 3+2 with two indexes. The other two for me were not proving to do what I was thinking. In what you have there I would make a dummy floor surface and try the pocketing. I couldn't get spiral work with the flat endmill. If you didn't want Helix motion I would swarf these and call it a day, but since you have specifically asked for that I have tried to point you in that direction as easily as possible. I would probably revert back to Unified with Morph between two curves and then try spiral there, but sorry just don't have a lot time today to do more than I have already done.

Kind of hoping Dylan, Aaron, Rekd, Colin, Jparis would chime in to offer there thoughts.

i think this is what Ron was mentioning
