9 Set the offset writing signal mode GOQSM to LOW.
The writing mode is canceled and the blinking “OFST” indicator light
goes off.
Procedure for setting the work coordinate system shift amount
Tool position offset values can be automatically set by manually moving
the tool until it touches the sensor.
Refer to the appropriate manual issued by the machine tool builder for
actual operation.
1 The tool compensation values are then calculated based on the
machine coordinates of the tool.
2 Execute manual reference position return.
By executing manual reference position return, the machine
coordinate system is established.
The workpiece coordinate system shifting amount is computed based
on the machine coordinate system of the tool.
3 Set the workpiece coordinate system shifting amount writing signal
mode WOQSM to HIGH.
(Refer to the appropriate manual issued by the machine tool builder
for actual operation.
)
The CRT display is automatically switches to the workpiece shifting
screen, the “WFST” indicator starts blinking at the status indicator
area in the bottom of the screen, which inform that the workpiece
coordinate system shifting amount writing mode is ready.
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.
Besides the tool offset number can be set automatically by setting the
tool offset number input signal (with parameter QNI(No.5005#5)=1).
Refer to the appropriate manual issued by the machine tool builder for
details.
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 by
manual handle feed.
The workpiece coordinate system shifting amount on the Z–axis is
automatically set.
8 Feed the tool.
9 Set the workpiece coordinate system shifting amount writing signal
mode WOQSM to LOW.
The writing mode is canceled and the blinking “WSFT” indicator
light goes off.
(Refer to the appropriate manual issued by the machine tool builder
for actual operation.
