11. TOOL FUNCTION
By specifying an up to 8–digit numerical value following address T, tools
can be selected on the machine.
One T code can be commanded in a block. Refer to the machine tool
builder’s 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:
(i) Simultaneous execution of the move command and T function
(ii)Executing T function commands upon completion of move command
The selection of either (i) or (ii) depends on the machine tool builder’s
specifications. Refer to the manual issued by the machine tool builder
