2D Adaptive Clearing cutting through model.

[ovisopa]

Hello guys, again with an issue I have regarding a 2D adaptive operation, when is milling the left part, it cuts from the right part, even if in the setup I selected both bodys.

The only way to do it is using an 3D adaptive operation ?

The 2D toolpaths are not model aware, they rely ONLY on the geometry you select with a very few exceptions (2D Chamfer for instance).

I wouldn't bother with 2D Adaptive on this setup, as it will simply  make more work for you later on.

I will try now the 3D adaptive operation, but it seems so much more complicated to make a 3D operation, as I haven't used any until now.

Here is your 3D Adaptive set up with a few modifications (changed the optimal load to the value you have in the first toolpath, and simplified the geometry selections):

You actually need very few selections for 3D Adaptive, which is one reason it is so powerful and useful. It can be much faster to program than 2D operations.

File attached.

Thank you, I downloded the file and look into it right now, I could do some 3D toolpaths , but I couldn;t make it mill to -5mm , as my contour was.

I will check your file and post back, in your screenshots there seems to me way more toolpaths than I needed, i want to mill just the top side, that is -5mm from the model top.

UPDATE.

I checked your file, and with very few adjustments (Bottom Height was changed to Model top -5mm, to limit the milling to that level and I also removed the 0.5mm axial offset)

The only thing I don't really like is the stepped milling on the angled wall, for roughing part of that wall I will use another smaller endmill with a larger corner radius, but for now it doesn;t other too much as it will lose only a few seconds to do those steps-up.

 Thank you @Steinwerks

UPDATE 2.

Also it seems it mills air, for a few  passes around the model, the stock contour  is not selected, maybe if I didn;t suppressed the previous operation, it will not mill so much air ? I tried now to activate the first operation, and it seems it stills mill air around the part

[Steinwerks]

The steps are for roughing 3D geometry, but you can change that by altering the Fine Stepdown value on the Passes tab. I would highly recommend changing the default Tolerance setting, .01mm would be much preferable to .1mm as the toolpath will deviate much less from the optimal load value that way (this applies to 2D Adaptive as well).

Edit: it should be noted that the 3D Adaptive path I altered would eliminate the need for all three of your previous toolpaths, which is the entire point of Adaptive Clearing in this instance and in general application

Excelent ideea, when I seen your toolpath going all the way down, I didn't thinked I could use only one operation to mill both the contour and the flat area at -5mm

I will continue now with the other mini endmills , to finish this part 🙂
