1.5.2.4 Automatic coordinate system setting
When ZPR (bit 0 of parameter No. 1201) for automatic coordinate
system setting is 1, a coordinate system is automatically determined
when manual reference position return is performed.
Once α, β, and γ are set with parameter No. 1250, a workpiece
coordinate system is set upon reference position return so that the base
point on the tool holder or the tip of the basic tool is positioned at X =
α, Y = β, and Z = γ.
This processing occurs as if the following are specified at the
reference position:
M
G92 Xα Yβ Zγ ;
T
G50 Xα Zγ ;
When the setting of a workpiece coordinate system shift amount is
other than 0, a workpiece coordinate system shifted by the amount is
set.
T
1.5.2.5 Workpiece coordinate system shift
Explanation
When the coordinate system actually set by the G50 command or the
automatic system setting deviates from the programmed work system,
the set coordinate system can be shifted.
Set the desired shift amount in the work coordinate system shift
memory.
