FANUC Series 30i-MODEL A
Input of tool offset value measured B
Basic procedure to set tool offset 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) Execute manual reference position return.
By executing manual reference position return, a machine coordinate system is stablished.
The tool offset value is computed on the machine coordinate system.
(2) Select manual handle mode or manual continuous feed mode and set
the tool compensation value write mode select signal GOQSM to “1”. The CRT di
splay is automatically changed to the tool offset screen (geometry), and the “OFS
T” indicator starts blinking in the status indication area at the bottom of the scree
n, which indicates that the tool compensation value writing mode is ready.When th
e tool setter function for a one–turret/two–spindle lathe is in use, the S1MES or S
2MES (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 GOQSM (offset
write mode) signal becomes 0.
(3) Select a tool to be measured.
(4) When the cursor does not coincide with the tool offset number desired to be set, move the
cursor to the desired offset number using the page key and cursor key.
The cursor can also be coincided with the tool offset number desired to be set utomatically
by the tool offset number input signals (when parameter QNI(No.5005#5)=1).
In this case, the position of the cursor cannot be changed on the tool compensation screen
using page keys or cursor keys.
(5) Near the tool to the sensor by manual operation.
(6) Place the tool edge to a contacting surface of the sensor by manual
handle feed.
Bring the tool edge in contact with the sensor. This causes the tool compensation value
writing signals to input to be CNC.
The tool compensation value writing signal is set to “1”, and the :
The following tool compensation amount write signals are set up according to the setting of
the TS1 parameter (bit 3 of No. 5004).
When the parameter is 0: +MIT1, –MIT1, +MIT2, –MIT2
When the parameter is 1: +MIT1 only
i) The axis is interlocked in this direction and its feed is stopped.
ii) The tool offset value extracted by the tool offset memory (tool
geometry offset value) which corresponds to the offset number
shown by the cursor is set up.
(7) For both X-axis and Z-axis, their offset values are set by operations (5) and (6).
(8) Repeat operations (3) to (7) for all necessary tools.
