Partially open pocket / island facing

[Kendo]

Getting frustrated trying to figure out the toolpath for this 2D cut...

The face with 4 holes thru is my focus

To me it looks like a pocket with 3 open sides and an island, should be easy right

But I'd like to calculate the cut from stock  model which is mostly air

I got an open pocket to work with 2D dynamic mill and using containment / avoidance areas

Now need to figure out the rest milling / machining from the stock

Seems like programming to the 3D model instead of 2D geo, Mcam would be able to figure out the stock without containment / avoidance

Maybe I'll figure that out next... I'll poke at it some more

I'd say this is textbook OptiRough. Or 3+2 Roughing if you've got it, great candiate for a 5ax

You'll need to feed it some machining faces, avoidance faces and then containment if you don't get what you're after. And play with your Z depths to not go too deep or too high and waste time.

Learning to leverage that toolpath is a game changer: for this part you should be able to ruff out the top of that steeple and the gallery below with one or two optirough paths. Two only if you don't like what you're getting with 1.

Absolutely.  The 2d toolpaths are not stock aware, so you'll need to create wireframe that represents your stock if you want to use them manually program that in.  That's why this is 100% Opti.

Thanks guys that's the right direction!

I was stuck thinking of everything under the 3D tab as "3D surfacing", not for prismatic parts like this

Need to get some training. I use 3D toolpaths all the time for 2D shapes.

It would be nice to have 2D dynamic rest paths work from a stock model, though, they would play well together with optirough that way

I completely agree.   All of the toolpaths I looked after are stock aware (hole making and multiaxis)

you can force optirough to 2D with the steep shallow

I'm also pretty certain that setting step up as the same as your step down will make it so it only machines all the flat areas on that plane.

It seems odd that that is how you sometimes have to do it. It might nice if they had a "Critical Depths" option similar to 3D Waterline. I remember when I first started using optirough and having a hard time getting it to machine all the flats I wanted.
