The AIR Command [MLPC]

The AIR command is used to control the supply of air to a device on the machine. It could be used to control a chip vacuum or spindle exhaust. This command is valid for all machine types but may not be available on a specific machine.

\textbf{AIR /} \begin{pmatrix} \begin{array}{l} \textbf{ON} \\ \textbf{OFF} \end{array} \end{pmatrix}

\textbf{AIR / ON} ,\mathit{seconds}

There are two methods of controlling the air device. The first method is used to turn the device on or off at different points in the machining operation. This is done by coding AIR/ON to start the device and AIR/OFF to stop the device. This is only valid if the air device is modal, meaning that the device will not shut off automatically, it must be instructed to do so.

The second method of controlling the air device is used to activate the device for a specific length of time and then shut it off. This is done by coding AIR/ON,seconds, where seconds is the amount of time the device is to remain active. The AIR/OFF command is not required as the device is automatically shut off after the time period has expired.
