(1) Execute manual reference position return.
By executing manual reference position return, a machine coordinate
system is established.
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 display is automatically changed to the tool offset screen
(geometry), and the “OFST” indicator starts blinking in the status
indication area in the bottom of the screen, which informs that the tool
compensation value writing mode is ready.
(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 by page key and
cursor key.
Besides, the cursor can also be coincided with the tool offset number
desired to set automatically 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 (+MIT1, –MIT1, +MIT2 or
–MIT2) to input to CNC.
The tool compensation value writing signal is set to “1”, and the :
i) The axis is interlocked in this direction and its feeding 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 value are set by the operations
(5) and (6).
(8) Repeat operations (3) to (7) for necessary tools.
(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.
