Tool Control Functions
Chapter 20
20-18
It is possible to alter or generate values in the tool offset tables (see section
3.1) by using the programming feature discussed in the following section.
It is possible to enter data in the offset tables by programming the correct
G10 command. The following section describes the use of the G10
commands.
Important: Note that G10 blocks may not be programmed when cutter
compensation is active.
A G10 code used to modify a tool offset table value will only change the
value in the table. If that offset value is currently being used by the
control, the active offset value will not be updated until the offset value is
called again from the table using a D or an H--word.
Any values entered in an offset table using the G10 command while the
control is in incremental mode (G91), are added to the currently existing
offset data. Any values entered in an offset table using the G10 command
while the control is in absolute mode (G90), are used to replace the
currently existing offset data.
The following is a representation of the basic format for modifying the
offset tables.
G10 L(10-13) P__ R__;
Where : Is :
L(10-13) Designates the definitions of the other parameter data being used in the G10
block. The L--word defines the other parameters as described in Table 21.A.
P see Table 21.A
R* see Table 21.A
* When setting tool length axis values, R can be replaced with the name of the axis (typically X, Y, or Z). Axis
names are always used by the control when offset tables are backed up by the control. If you use an R to set
a tool length value, it is applied to the axis currently selected as the tool length axis. See page 20-9 for
details on selecting the active tool length axis.
