4.5 Polar coordinates interpolation (G12.1, G13.1)

4.5 Polar coordinates interpolation (G12.1, G13.1)
An interpolation between a rotary axis and a linear axis in the machining plane is switched
on or off via G12.1 and G13.1. Another possible linear axis lies vertical to this plane.
This function corresponds to the TRANSMIT function in the Siemens mode.
Note
A detailed description of the TRANSMIT function can be found in the NC function description
"SINUMERIK 840D, Extended Functions", Chapter "Kinematic Transformation (M1)" and in
the work planning programming manual (PGA) "SINUMERIK 840D" in Chapter
"Transformation".
G12.1 is based on the Siemens function TRANSMIT. Appropriate machine data is to be set
for this.

G13.1
On specifying G12.1, the relevant previously used plane (G17, G18, G19) is deselected.
Operation with polar coordinates interpolation is deselected via NC RESET, where the
previously active plane is activated again.
Possible G functions in operation with polar coordinates interpolation
G01: Linear interpolation
G02, G03: Circular interpolation
G04: Dwelling, exact stop
G40, G41, G42: Cutter radius compensation
G65, G66, G67: Customer macro command
G90, G91: Absolute command, incremental command
G94, G95: Feedrate per minute, revolutional feedrate
