3d Adaptive unexpected behaviour

[designingberlin]

Hi,

I have a little issue I don't understand. The screenshot shows an adaptive toolpath. Mostly with the expected stepover. Just in the center the stepover is increased and I just don't know why. Any ideas.

f3d file is attached

• The stock is the actual casted part
• The body in the manufacturing setup is the final part
• The adaptive toolpath is contained within a closed sketch contour

Any ideas?

Thanks,

Stefan

Its most likely removing an island of material

the stepovers going around corners like that look incorrect but you must remember that the toolpath is from the center of the tool, the width of the material being cut isn't larger than the optimal load.

If you look at the toolpath running in simulation you will see it is likely correct

Yes. I checked that. tool load is fine. I ran the production parts like that.

It just seems very unexpected. I thought there might be a deeperreasoning behind that behaviour. Usually adaptive toolpath make a bit more sense to me.

It's because its milling a "triangle", not a rectangular shape. It will never voilate the max stepover, so it IS expected.
