See the following illustration for drilling axis of G18:
Using AXN (number of the drilling axis) to program the drilling axis enables the drilling axis to be directly programmed.

If Y-axis is present.
For example, to machine a center hole (in Z) in the G17 plane, you program:

AXN=3
Programming example: Tapping without encoder
Tapping is carried out without encoder at position X0; the drilling axis is the Z axis. The parameters SDR and SDAC for the
direction of rotation must be assigned; parameter ENC is assigned the value 1, the value for the depth is the absolute value.
Lead parameter PIT can be omitted. A compensating chuck is used in machining.

Programming example: Tapping with encoder
This program is used for tapping with encoder at position X0. The drilling axis is the Z axis. The lead parameter must be
defined, automatic reversal of the direction of rotation is programmed. A compensating chuck is used in machining.
