Rest material milling

Sometimes you have a large pocket and you want some sharp edges or it has some spiky contours.
So you would like to mill 99% of the pocket with a big mill and only the parts that mill isn’t able to mill with a smaller one.
Like this example.


Something like rest material removal.
I know this is hard to implement because it depends on the previous operations. And I don’t even know if it is possible with your software concept.
But may you keep it in mind :wink:


Another thing is snapping of a circle’s center or a corner to the grid. Have I missed something or is that not possible?
And what are action points? I couldn’t find something about that in the manual…

What I usually do in this case is to rough out the pocket as you have shown, then do a contour pass with the smaller end mill, maybe two passes with a larger offset on the first if you have more in the corners than a single pass will get. Not exactly rest machining, but it usually works out pretty well.

Yes, rest milling is a hard nut to crack. It’s one of those functions I look at occasionally when I’m feeling particularly masochistic. So far I haven’t come up with anything that works reliably.

Yes that is sometimes a workaround, but on parts with a large contour line and a little area it makes sometimes no difference to mill all with the small mill.
On simple parts like rectangles where a want to have sharp edges I add a layer which only handles the edges.

:mrgreen:

Snapping to circle’s center is not yet implemented, isn’t it?

Snapping where? Measure for instance should snap to the centre if there is a blue cross.

Snapping to the grid when moving a Part.
If I have a part with a hole and want the hole to be centred in the origin.

Isn’t that accomplished by just clicking on translate, choose the center of the hole and type in 0,0? That’s how I do it.

Ok. Yes that’s the only way I can do it actually.
