When assist gas is output with G32, the shutter is opened. When the
output of assist gas is stopped with G32P0, the shutter is closed.
Whether to use flow pattern specification or direct gas pressure control
specification is determined by the specification following G32. However,
the method to be used may be ambiguous, depending on the specification.
In such a case, the method to be used is determined by the setting of bit
0 of parameter No. 15004.
With this method, assist gas is output without changing the pressure, and
machining is started after assist gas has been output for a certain period
(gas pressure settling time). When the machining is stopped, the output
of the assist gas is also stopped.

P_: Assist gas type
T_: Assist gas pressure
R_: Assist gas pressure settling time
For the correspondence between the assist gas numbers and the types of
assist gas that are actually output, refer to the operator’s manual provided
by the machine tool builder.
When P0 is specified, the output of the assist gas is stopped.
