Polar coordinates G110/G111
• G110 Adopt last programmed position as new centre point
• G111 Polar coordinate programming with angle and radius
Functions G110 and G111 simplify zero programming of polar coordinates. These functions
are only effective in the block. They are only valid for linear interpolation. Before a block with
G110, a block with G10 or G11 must be programmed. The F value (G11) or rapid traverse
(G10) last programmed is valid as feedrate. No axis movement can be performed in the block
with G111.
Example with G110:

N05 G0 X0 Y0
N10 G11 X0 Y0 A15

N15 G110 A30 B30
