(9) Set the tool compensation value writing mode signal GOQSM to “0”.
The writing mode is canceled and the blinking “OFST” indicator light
goes off.
When the tool setter function for a one–turret/two–spindle lathe is in
use, the S1MES or S2MES (spindle under measurement) signal for
the spindle being measured becomes 0.
To use the tool setter function for a one–turret/two–spindle lathe, first
specify the spindle to be measured, using the S2TLS <G040.5> (spindle
measurement select) signal.
(1) Set the tool geometry offset values of each tool in advance.
(2) Execute manual reference position return.
By executing manual reference position return, the machine
coordinate system is established.
The workpiece coordinate system shift amount is computed based on
the machine coordinate system of the tool.
(3) Set the workpiece coordinate system shift amount writing mode
select signal WOQSM to “1”.
The CRT display automatically switches to the workpiece shifting
screen, the “WFST” indicator starts blinking at the status indicator
area in the bottom of the screen, which indicates that the workpiece
coordinate system shift amount writing mode is ready.
When the tool setter function for a one–turret/two–spindle lathe is in
use, the workpiece coordinate system screen is selected, and the
S1MES or S2MES (spindle under measurement) signal, whichever is
applicable, becomes 1.
NOTE
After this, it is impossible to switch the S2TLS (spindle
measurement selection) signal until the WOQSM (offset
write mode) signal becomes 0.
(4) Select a tool to be measured.
(5) Check tool offset numbers.
The tool offset number corresponding to the tool required for
measurement, shall be set in the parameter (No.5020) in advance.
The tool offset number can also be set automatically by setting the
tool offset number input signal (with parameter QNI(No.5005#5)=1).
(6) Manually approach the tool to an end face of the workpiece.
(7) Place the tool edge to the end face (sensor) of the workpiece using
manual handle feed.
When the tool edge contacts the end face of the workpiece, input the
workpiece coordinate system shift amount signal WOSET.
The workpiece coordinate system shift amount on the Z–axis is
automatically set.
(8) Release the tool.
(9) Set the workpiece coordinate system shift amount write mode select
signal WOQSM to “0”.
