Angled Pocket Surface

[Mic6]

Hey guys, I'm having the worst time trying to get this arm pocket area roughed out. I can get a toolpath to stay within the containment, but I don't want it retracting so high, or cutting all that air. The green lineis my containment, and all of the material above that has been roughed out. All I want to do is rough the inside of the arms. Any suggestions?

 

 

[Teh Bear without Brains kinda idiot]

surface rough rest milling or HS rest roughing or pocket tp put mask on it and use it in surface project or even trim toolpath

simply create a trim boundary in FRONT then use it with toolpath trim to remove the unwanted moves

[Odin]

You could use a scallop and leave stock. Go from outside in. use the largest tool that will fit in the pocket. a fluted flat endmill would work if the flutes are long enough.

[Smrk]

You could create surface that cover hole, on this surface use "surface finish toolpath" and than rest roughing toolpath in normal (non covered) surfaces.

what about use solid as your material stock ?

Just cover this pocket before ,

Than rough against file.

HS Rest Roughing FTW! Thanks guys for all the suggestions. I'm still trying to work out the retracts, but it works great.

Post the MCX on the FTP or at least some basic dimensions so I can recreate this and have at it.

Sorry, that's about all I can show

Have you tried the Incremental retracts, that might get rid of the long retracts.

[Müřlıń®]

Use a surface finish contour and leave stock down to the flat then rough pocket.

[Mic6]

Okay guys, I have the part roughed(thanks again), but my brain is killing me trying to finish the insides of these arms. I created surfaces on the areas I'm trying to finish and attached them. I've tried all kinds of HS Finish, waterline, contour, and nothing seems to work right. 3D contour got close, but it just gouged the floor.

How about surface finish parallel the floors and a surface finish project the

walls and rads providing you can use the same size ballnose as the corner rads?

Surface Finish Blend?

 

I am guessing the lite purple area's are what need doing.

Hey Jason, I shouldve mentioned, the floors are finished with SF Parallel. The walls/rads are the problem. I'm not sure what toolpath I would project onto that surface.

Lite Purple is correct. I'll try blend.

If your tool is size to size for the rad, a Finish Project should work too

Mic,

 

I would create a Contour Toolpath above those surfaces, then use Surface Finish Project and project the NCI from the Contour down onto those surfaces. You'll need to make copies of the Floor surfaces, un-trim them, then extend them beyond the walls (so Project has something to "project" onto).

[Colin Gilchrist]

Blend would not work for those surfaces, unless you want to finish those walls using zig-zag passes. (I think that would end up wasting a bunch of machine time because those walls are vertical. If they were angled outwards, then I would agree with using Blend.)

I agree with Colin, based on the tool. If it's size to size Project is the better way to go for sure.

Will update with results...uggh

[MotorCityMinion]

If somebody saves this as a solid and can upload it, I have an idea I'd like to try.

[MotorCityMinion]

Best I could do with out a model...

 

Blend rules. No wasted moves on the verticals. Set to Along, 2D, Spiral, .0002 TT, .008 Step over. 1/4 ball cutting a 3/16 rad with .04 over thickness on the floor

 

[TheePres]

Curve 5-axis locked to to 3 with floor as compensation surface would also work.
