13. Reserved m
OEMIPO2
##
14. Reserved m
CT 15. Circle with tangential transition m
G34 16. Increase in thread pitch (progressive change) m
G35 17. Decrease in thread pitch (degressive change) m
INVCW 18. Involute interpolation in CW direction m

If no function from the group is programmed with modal G functions, the default setting
(which can be changed in the machine data) applies: $MC_GCODE_RESET_VALUES
## The keyword is not valid for SINUMERIK 810D/NCU571.
