TOOL OFFSET (Cont'd)
2.12.1.2 H and D functions
(H,
D
codes)
The tool offset No. is specified by a 2-digit number (& 3-or 4-.digit number)
following address H or D.
H
:
r
=
Di¬
or
Tool offset No.
Two
types
of H.
D function methods are available, which
can
be selected
by
parameter.

Tool offset Nos. [01]
to
[99]
directly correspond
to
99
tool offset value
memory
Nos. That is. the offset
amount
stored in the tool offset value
memory
of the specified
No. is
used.
<5> Tool
offset No.
[00] (H00,
D00) have different meanings
depending
on
each correction function. For details, refer
to
the description of
each G-function.
Discrimination of H and D code
usage
O
The H and D codes (used to specify a tool offset No.) must be used
differently depending
on
the offset function as
follows:
Table 2.12.3 Usage
of H and G Codes
Code Usage
Tnol length offset H Code
D Code Tool position offset or
tool radius
compensation
@
However,
the tool offset Nos. "01"
to
"99"
and the H
or
D codes
may
be
used in
any
desired combination. For
easy
programming, however,
it is recommended that the H code be selected from HOI
to H30, and
the D code be selected from D31
to
D99.
