FANUC Series 30i-MODEL A
Input of tool offset value measured B
(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.
Basic procedure to set workpiece coordinate shift value
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”.
