multi axis pocket

[G1CNC]

Hi guys. any ideas what the best 5 axis toolpath would be to rough and finish this pocket?

I've tried multi axis pocketing but the software seems to want to hang up when i calculate it.

I'm guess swarf is the best way to go?

Any help appreciated.

Thanks

5-ax pocketing is not adequate here as your machining geometry floor is not radial. And then even if you create an imaginary floor surface

which could be radial ( like the top of your part ) then the tool axial deflections will not help to clear out the external surface undercut.

I would suggest a 3-ax roughing strategy and then swarfing.

Cool part!    The answer here is, of course, it depends.    How big is the part, what material, how big is that slot, how deep it is, how much undercut, etc.

Depending on slot width, Multiaxis Pocketing could help you with the roughing part, but you can either use it in Dynamic mode which will not do undercuts (it's always normal to the floor surface), or you have to use Offset style roughing to do the undercuts.

If you're thinking of slotting it and want to spiral from the middle outwards and tilt away from the walls, I'd use Morph, and on the Cut Pattern page make sure to set the Cut Order to "From Center away," that'll cause it to start with in the middle and then cut each slice towards the outside.   Collision control the inside walls with automatic tilt should get your angles nicely.

Then finish the walls with Swarf.

The grove remind me of a o-ring grove, and if it is it's probably not very big or deep..

The first thought I had was maybe try 5x curve ...

just my 2 cent worth lol

Tough to be certain as it's only a pic and size is lost...

I might go ahead and use a ramp cut converted to a 5 axis path to rough and swarfs for the walls, really need to ballmill the floor for finish, 5 axis flow perhaps

Agreed wit JP, we do similar parts, We 5X swarf the walls and surface the floor and rads on the top. (Tapered pintles is where all the fun is at)
