In the example above, the same machine group contains tool posts for
four paths. In the ZX plane coordinate system with its origin placed
at the reference position of tool post 1 of path 1 in the same machine
group, the position of the reference position of tool post 2 of path 2 is
specified by setting the value ε
1
of the X component in parameter No.
8141 for path 2 and by setting the value ξ
1
of the Z component in
parameter No. 8143 for path 2.
Similarly, In the ZX plane coordinate system with its origin placed at
the reference position of tool post 1, the position of the reference
position of tool post 3 of path 3 is specified by setting the value ε
2
of
the X component in parameter No. 8141 for path 3 and by setting the
value ξ
2
of the Z component in parameter No. 8143 for path 3. In the
ZX plane coordinate system with its origin placed at the reference
position of tool post 1, the position of the reference position of tool
post 4 of path 4 is specified by setting the value ε
3
of the X component
in parameter No. 8141 for path 4 and by setting the value ξ
3
of the Z
component in parameter No. 8143 for path 4.
The unit of setting is the least input increment. For an axis based on
diameter specification, make a setting using a diameter value.
WARNING
Measure (ε
1
, ξ
1
), (ε
2
, ξ
2
), and (ε
3
, ξ
3
) in the state
where reference position return operation is
completed for all axes (the tool is at the reference
position.)
After modifying parameter No. 8141 and No. 8143
for each path, be sure to perform a reference
position return operation along all axes in all paths.
Otherwise, the internally stored positional
relationships of the tool posts are not updated to the
newly set parameter values.
