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).
S 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.
S 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).
S QNI = 0 (manual selection)
Specify the desired tool compensation number in parameter No. 5020.
S 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.
