Reviving a thread from the dead...
Many Fanuc machines do have a circle command. They Use G12.2 and G13.2
Their lead-in and lead-out cuts are a bit different. Fanuc leads in with a 45 degree linear cut then does a quarter-circle arc to the edge of the main circle (abd thre reverse on the way out) Most other machines do a full 180 degree lead-in/lead-out arc. Mach3 just does a horizontal linear cut to the edge.
Fanuc and Mitsubishi the only machines that I have seen that that support circle operations (not to be confused with G02/G03 arcs) in planes other than the G17 XY plane.
