- 185 -
- Tool holder offset
The machine-specific length from the rotation center of the tool rotation
axes (A- and B-axes, A- and C-axes, and B- and C-axes) to the tool
mounting position is referred to as the tool holder offset. Unlike a tool
length offset value, a tool holder offset value is set in parameter No. 7648.
When tool axis direction tool length compensation is applied, the sum of
the tool holder offset and tool length offset is handled as a tool length for
compensation calculation.

- Rotation axis origin compensation and rotation axis offset
This function compensates for a slight shift of the rotation axis origin
caused, for example, by thermal displacement. .
Set offsets relative to the rotation angles of the rotation axes in
parameter.
