Adaptive Path/CAM Operation

[RatonLaveur]

I like this idea of reducing linking moves. In some use cases it would be extremely helpful. When milling pockets this would homogenize the sidewalls quality quite nicely.

I need a couple of definitions:

Operation Type - Profiling vs clearing? - not clear what this means. Not seeing a change when I change this?

Finishing Profile - could mean a few things - might be a spring pass?

Use outline One place said this means to ignore holes? Not sure what it is supposed to do?


There is an Accuracy vs performance slider - which end is which? Turns out max accuracy is to the left.

Hello,

when I am milling pockets with the Adaptive Tool, the milling works in "same direction" (german: Gleichlauf)

Is it possible to have the milling process work in counter direction (german: Gegenlauf) with the Adaptive tool?
Where can I configure this if possible?

Many thanks
Josef

Do you mean 'conventional' vs 'climb' milling?

The adaptive operation only supports climb milling at this time. Support for conventional milling has been discussed but nobody has stepped up to do it.
Since adaptive is generally considered a roughing operation, there isn't a lot of benefit in supporting conventional milling.

[spitzlbergerj]

Thank you very much for the answer. Especially the reference to the use as a roughing operation helps me. With that, I can understand.

To clarify my question, here is a picture of what I mean. But I think you have already understood me correctly.



May I add one more question?

If adaptive is the roughing operation, can I use the Contour operation on a pocket as well? Or what would be used to mill the contour of the pocket cleanly then?

Sorry for these questions, I am just getting started with CNC. Thanks for the understanding.

Regards
Josef

This is indeed the German equivalent of climbing vs. conventional.

For contour only You would rather use the PathProfile operation than PathPocket.

Thank you @chrisb. This helps!

Hi everyone.
I am a mechanical engineer from Toulouse France.
I'm new to this forum and to freeCad but I've been using Fusion360for a while and so I have a bit of experience in the field.
Prices on Fusion360 has decided me to get out and form myself to freecad.

Anyway, lets get to the point.
I have designed this small part and am trying to make an efficient path to mill it on my CNC

I have found that not to mill a side, a dressup can be applied on an operation (not to mill attachments) and was glad with that.

But as you can see this adaptative only mills the walls of my part and not the faces although it is the horizontal faces that I selected.

How can this be done ? Can I mill the selected faces with adaptive or do I need to use another strategy.

Other question, what are the extensions (for milling inner corners ?)

One last thing: Shouldn't the keep tool down ration be a no dimension number?

Thanks for the work already accomplished and thanks in advance to those who will take time to answer.

I'm getting to understand how this work.
First, this is not at all aware of the part. And will cut in it if you tell it to.

In fact, it is rather a digging around a sketch down to a certain depth.
So, to mill the face at 5mm, I have to select edges or faces that the path will clear outside of.

So in my case, the most simple is to select the top faces of the 4 corners and set the final depth to 5mm.
