• If the tool setter function for a one-turret/two-spindle lathe is
used
For the tool set function for a one–turret/two–spindle lathe, the
workpiece coordinate shift amount for the Z–axis is
automatically set in any of workpiece coordinate systems G54 to
G59 for workpiece coordinate system memory.
[Z–axis workpiece coordinate system shift amount to be set up] =
–([corresponding Z–axis tool geometry compensation amount]
– [Z–axis machine coordinate value])
Select the desired workpiece coordinate systems from G54 to
G59 manually or automatically, using the 2AT parameter (bit 1
of No. 5051).
- 2AT = 0 (manual selection)
Set the cursor to the desired workpiece coordinate system
G54 to G59
by operating the MDI (such as page and cursor keys).
NOTE
It is inhibited to select an external workpiece
coordinate system offset (EXT). If the cursor is set
to it, the warning message ”Write inhibited” is
displayed when the workpiece coordinate system
shift write amount signal becomes 1.
- 2AT = 1 (automatic selection)
Previously set any of workpiece coordinate systems G54 to
G59 in parameter No. 5054 for spindle 1 and parameter No.
5055 for spindle 2. When the workpiece coordinate system
shift amount write mode is entered, the cursor is set to any
of workpiece coordinate systems G54 to G59.
NOTE
If 0 or a value out of the valid data range is set in
parameter No. 5053 or 5054, workpiece coordinate
systems G54 and G57 are set up, respectively, for
spindles 1 and 2.
Also select a tool compensation number to be used in
measurement manually or automatically, using the QNI
parameter (bit 5 of No. 5005).
- QNI = 0 (manual selection)
Specify the desired tool compensation number in parameter
No. 5020.
- QNI = 1 (automatic selection)
The cursor is set to the desired tool compensation number,
using the tool compensation number input signal.
For spindle 1, the cursor is set to a tool compensation
number selected by the input signal.
For spindle 2, the cursor is set to the sum of the value
specified in parameter No. 5053 and the tool compensation
number selected by the input signal is used.
