Fantastic! This tool is most useful to less experienced machinists so that is great news.

Arbitrary? How very dare you!
The included chiploads are interpolated from published data. I believe the data suggested that anything below this rate would be considered rubbing rather than cutting, therefore lead to increased heat and tool wear.
If there is a need to allow lower values, I'm happy to have a look at it.

Is a negative stepdown desired for things like 3-d printing, or is that handled elsewhere? I would think that, at least, the negative stepover would cause problems with the rest of Path.
I was also able to enter negative surface speeds as well. Does that mess up FreeCAD elsewhere?
I think that the power calculation should stop increasing when you exceed a stepover greater than the tool diameter.
