(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 screen is automatically changed to the tool offset screen
(geometry), and the “OFST” indicator starts blinking in the status
indication area at the bottom of the screen, which indicates 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 using the page
key and cursor key.
The cursor can also be coincided with the tool offset number desired
to be 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 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.
(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.
(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.
