4th axis mill info…GeoPath Mill doesn’t automatically know you want full 4th-axis vs.
indexing 4th-axis. Unlike GeoPath Lathe, which presumes ZC mode (turning and milling), GeoPath Mill presumes you want indexing only unless you do something special.
+ You’ve activated the 4th-axis setting correctly.
+ You’ve made a Contour cut correctly.
To make this a full 4th-axis mill cut, add the following:
+ Put the Contour cut in a Macro (add a number to the Contour Cut Info
window’s “Cut is in Macro” box).
+ Make a Macro Cut > Convert to rotary axis, and enter the radius to the
OD of the bar in the “Radius” box.
Attached is an example of this.
With the “Convert to rotary axis” Macro, you can control / have separate
wrapped 4th-axis cuts vs. just indexing 4th-axis cuts in the same program.
Remember that if everything is wrapped in the entire program, you can
just cut the part flat, then use Save+Make Program > NC-Utilities > Wrap
XY Around Rotary Axis to output a wrapped 4th-axis mill program.

+ if converting to G-code, use a post that is full 4th-axis (M901, M904
for example). + the round(-ish) corners become helical arcs when wrapped, so these
output as dozens of small XYZB moves. In Mazatrol (as a Manual
Process), this is a large number of shape lines – you might want to
activate the MAZMAC.INI setting “ManPgmAsEIA=1”, so that this makes a
Mazatrol main program and an EIA sub-program (with 4th-axis mill cuts in
the EIA sub).
