There are two methods for specifying a T code as shown in Table 15.1.2(a)
and Table 15.1.2(b).
Table 15.1.2(a)
Kind of
T code
Meaning of T code Parameter setting for specifying of
offset No.
2–digit
command
T f f
Tool wear and tool
geometry offset
number
Tool selection
When LD1, bit 0 of
parameter
No.5002, is set to
1, a tool wear off-
set number is spe-
cified with the last
digit of a T code.
When LGN, bit 1
of parameter
No.5002, is set to
0, the tool geome-
try offset number
and tool wear off-
set number speci-
fied for a certain
4–digit
command
T ff ff
Tool wear and tool
geometry offset
number
Tool selection
When LD1, bit 0 of
parameter
No.5002, is set to
0, a tool wear off-
set number is spe-
cified with the last
two digits of a T
code.
fied
for
a
certain
tool are the same.

certain
tool are the same.
Tool selection is made by specifying the T code corresponding to the tool
number. Refer to the machine tool builders manual for the relationship
between the tool selection number and the tool.
Tool offset number has two meanings.
It is specifies the offset distance corresponding to the number that is
selected to begin the offset function. A tool offset number of 0 or 00
indicates that the offset amount is 0 and the offset is cancelled.
15.1.2
T Code for Tool Offset
Format
D Lower digit of T code
specifies geometry and
wear offset number
D Lower digit of T code
specifies wear offset
number and higher digit
number specifies tool
selection number and
geometry offset number
15.1.3
Tool Selection
15.1.4
Offset Number
