- Tool offset specification code
Two types of tool offset specification codes are used: H code (for tool
length compensation) and D code (for cutter compensation). A number
not exceeding three digits (999) can be specified as a tool offset
specification code, but a specified number must not exceed the number
of tool offsets usable with the CNC.
NOTE
When codes specifying tool offset values are not
used, registration can be omitted.
- Tool change type
For tool life management, the four tool change types (types A to D)
indicated below are available. The type used varies from one machine
to another. For details, refer to the appropriate manual of each machine
tool builder.

Tool group number specified
in the same block as the tool
change command (M06)
Previously used
tools
Tools to be used next
Tool life count timing
Life counting is performed for a tool in the specified tool group
when M06 is specified next.
.
Life counting is
performed when a
tool in the tool group
specified in the
same block as M06
is specified
Remarks
If a T command
(return tool group)
after M06 does not
match the tool
group currently
being used, an
alarm (PS0442) is
issued (when bit 6
(ABT) of parameter
No. 7400 = 0).
Normally, when a tool group number is
specified by itself, type B is used.
However, no alarm is raised even if the
tool group number is specified by itself as
type C
When only M06 is
specified, P/S
alarm No. 0440 is
issued.
NOTE
When a tool group number is specified and a new
tool is selected, the new tool selection signal is
output.
