If R is specified with I and K, only R is effective.
If an additional axis other than the X– and Z–axes is provided, circular
threading can be specified for a plane other than the ZX plane. The
method of specification is the same as that for G02 and G03.
The G36 command is used to specify the following two functions:
Automatic tool compensation X and counterclockwise circular threading.
The function for which G36 is to be used depends on bit 3 (G36) of
parameter No. 3405.
D When parameter G36 is set to 0, the G36 command is used for
automatic tool compensation X.
D When parameter G36 is set to 1, the G36 command is used for
counterclockwise circular threading.
Automatic tool compensation using G37.1/G37.2
G37.1 can be used to specify automatic tool compensation X and
G37.2 can be used to specify automatic tool compensation Z.
