G12 Circular Pocket Milling CW / G13 Circular Pocket Milling CCW

These G-codes mill circular shapes. They are different only in that G12 uses a clockwise
direction and G13 uses a counterclockwise direction. Both G-codes use the default XY
circular plane (G17) and imply the use of G42 (cutter compensation) for G12 and G41 for
G13. G12 and G13 are non-modal.

D - Tool radius or diameter selection**
F - Feedrate
I - Radius of first circle (or finish if no K). I value must be greater than Tool Radius, but less
than K value.
K - Radius of finished circle (if specified)
L - Loop count for repeating deeper cuts
Q - Radius increment, or stepover (must be used with K)
Z - Depth of cut or increment

indicates optional
To get the programmed circle diameter, the control uses the selected D code tool size.
To program tool centerline select D0.
NOTE: Specify D00 if you do not want to use cutter compensation. If you do
not specify a D value in the G12/G13 block, the control uses the last
commanded D value, even if it was previously canceled with a G40.
Rapid-position the tool to the center of the circle. To remove all the material inside the
circle, use I and Q values less than the tool diameter and a K value equal to the circle
radius. To cut a circle radius only, use an I value set to the radius and no K or Q value.

Example G13 multiple-pass using I, K, Q, L, and G91:
This program uses G91 and an L count of 4, so this cycle will execute a total of four times.
The Z depth increment is 0.500. This is multiplied by the L count, making the total depth of
this hole 2.000.
The G91 and L count can also be used in a G13 I only line.
