Package: freecad:
Version: 0.20.2+dfsg1-4
This problem also exist in version 1.0.2+dfsg-1 in testing.
When trying to output G-code from the FreeCAD CAM module using the fanuc
postprocessor, I get a exception backtrace because the postprocessor try
to handle thread taps, while the surrounding code in FreeCAD do not seem
to support tool types.
>From the internal console:
20:24:40 Running the Python command 'CAM_Post' failed:

The problem need either horizontal or vertical feed rate or spindle
speed to trigger. The error above showed up when creating a simple
cylinder, creating a CAM job with fanuc as the post processor, adding a
simple facing operation on the top end of the cylinder, and then setting
feed rates to 150 mm/min and spindle speed to 1000.
I see the same problem discussed in
<URL: https://forum.freecad.org/viewtopic.php?t=74878 >, and
modification in the upstream code which seem related in
<URL:
https://github.com/FreeCAD/FreeCAD/commit/bd24577184e44f29d6b11baa950dda1bf28e21fe

and the following commit for that file.
I am not aware of any sensible workaround for this yet, and believe it
make FreeCAD CAM kind of useless for use with Fanuc CNC controllers.
