Not in the pure sense, no. However, when in C axis mode, the Gcode 'looks' cartesian - X = Xaxis, Y axis becomes C, and the cartesian to polar conversion is done in L_CNC - this gcode file is a simple square:
Code:
G8
G18 ; select XZ plane
T1 M6 ; tool - 1
G01 X20 Z50 F800 ;
G0 C0
G12.1 ; C axis mode
G01 X20 C20 F800 ; = X20 / Y20 - first corner of the square
G01 X-20 C20 F800 ;2nd
G01 X-20 C-20 F800 ;3rd
G01 X20 C-20 F800 ;4th corner
G01 X20 C20 F800 ; end at first corner
G53 G01 Z0 F800 ; get z to safe place, then x , then return c to 0
G01 X0 F800
G0 C0
G13.1 ;switch to TURN mode

Tool offsets/cutter diameters, etc, you would have to take care of, as the above Gcode file puts the center of the tool on the X20/Y20 co-ord, ie, on the corner of the square, not offset by the cutter radius, if milling. A drill would have no diameter offset, but you may enter G43 Hxx for any length offsets, etc. if desired....
For axial drilling, perhaps simply move the drill to co-ord - G01 X20 C20 F(feedrate of the move- which will be a coordinated move, ie, Caxis and X axis), and at the end of the move, use Gcode to drill with the Z axis as normal. I have not tried it, but you may be able to do a rapid (G00) to the X20C20 position, and then Zdrill, since you only want the drill at the X20C20 position and are not interested in how it gets there, ie, G01 coordinated move would 'mill' the contour ( a straight line) in the workpiece - this gets the tool to the end point, but wastes time.
My lathe has no radial drill/mill capability - the live tool axis is fixed in line with the lathe spindle axis, so have not even considered radial drilling/milling, but daresay it could be handled in the same way as proposed above - after G12.1, a G01 Cxx would move Caxis to that angle ( ie, no X axis move in the command is then only a Caxis rotation, no coordinated X/C move. That could line up the workpiece periphery at an angle that the radial drill will move along. If the radial drill is fitted to the X axis, then a G01 Xxx would move the drill into the workpiece - refinement needs more thought - radial peck drilling, etc - normally a Z axis motion - not sure of the drilling Godes works in X?
Been a while since I powered the little lathe on - 99% of my lathe work is on the manual lathes I have - The little CNC lathe was an exercise in design and build and turned out very nice indeed, but in my shop, it is a solution in search of a problem...
