11. TOOL FUNCTION (T FUNCTION)
117
By specifying a 2–digit/4–digit numerical value following address T, a
code signal and a strobe signal are transmitted to the machine tool. This
is mainly used to select tools on the machine.
One T code can be commanded in a block. Refer to the machine tool
builders manual for the number of digits commandable with address T
and the correspondence between the T codes and machine operations.
When a move command and a T code are specified in the same block, the
commands are executed in one of the following two ways:
1. Simultaneous execution of the move command and T function
commands.
2. Executing T function commands upon completion of move command
execution.
The selection of either sequence depends on the machine tool builders
specifications. Refer to the machine tool builders manual for details.
