Distance along the X axis between the reference positions of tool post 1 and tool post n in the same
machine group
8143
Distance along the Z axis between the reference positions of tool post 1 and tool post n in the same
machine group
[Input type] Parameter input
[Data type] Real path
[Unit of data] mm, inch (machine unit)
[Min. unit of data] Depend on the increment system of the applied axis
[Valid data range] 9 digit of minimum unit of data (refer to standard parameter setting table (A))
(When the increment system is IS-B, -999999.999 to +999999.999)
Each of these parameters sets the distance between the reference positions of the tool post
of path 1 and tool post of each path in the same machine group.
Set 0 in parameters Nos. 8141 and 8143 for tool post 1 of each machine group.
For the lathe system, only a Z-X coordinate system based on parameters Nos. 8141 and
8143 is used for setting.
Tool post 4
Tool post 3
Tool post 2
The tool post of path 1 in the
same machine group is used as
the reference tool post.

In the example above (Fig. 8.4 (n), 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
ζ
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
ζ
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
ζ
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.
