Title
Draw
When the tool change type is the ATC type (bit 3 (TCT) of parameter No. 5040 = 1),
commands are specified in the same manner as for the M series except that H99 and H00
are not used for the T series. See the description for the M series. For details on the tool
compensation types applied when the tool change type is the ATC type, see the lathe system
user's manual , "Ⅱ Programming; 5.7 Extended Tool Selection (B-63944EN-1)".
The command specification method for the turret type (bit 3 (TCT) of parameter No. 5040 =
0) is explained below.
CAUTION
This function cannot be used when the same number as the tool
selection number is to be used to specify a geometry offset number
(bit 1 (LGN) of parameter No. 5002 = 1).
- Commands
T○○○○○○99;
The tool life management function ends counting the life of the tool used so far, selects,
from the group specified by ○○○○○○, a tool whose life has not expired, outputs the T
code signal for the tool, and starts counting the life of the tool.
Example: Suppose that when a T199 command (with a tool offset specified with the lower
two digits) is issued, the life management function selects T10001 of tool group 1.
Then, T code 100 is output, and the tool offset number 1 is selected.
When the condition that a new tool be selected is not met, and the second or subsequent
selection of the same group is made since the control unit entered the automatic operation
start state from the reset state, the next to the currently selected T code is selected if more
than one offset is registered.
If the third selection is made, for example, the third offset is selected among multiple offsets
registered for the same tool.
Example: Suppose that the tool offset is specified with the lower two digits, and that two
offset numbers are set for the same tool number with the following two T codes:
T10001 T10002
The first T199 command issued since the control unit enters the automatic operation
start state from the reset state selects the first T code, T10001. Then, when T199 is
issued again before the control unit is reset, the second T code, T10002, is selected.
Furthermore, when T199 is issued again before the control unit is reset, the second T
code, T10002, is selected because the third offset is not present.
If bit 1 (TSM) of parameter No. 6801 is set to 1, life counting can be performed for
each T code even when T codes specifying multiple offsets for the same number are
registered.
