(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 shifting amount is computed based
on the machine coordinate system of the tool.
(3) Set the workpiece coordinate system shifting amount writing mode
select signal WOQSM to “1”.
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).
(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.
When the tool edge contacts with the end face of the workpiece, input
the workpiece coordinate system shift amount signal WOSET.
The workpiece coordinate system shifting 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”.
The writing mode is canceled and the blinking “WSFT” indicator
light goes off.
[Classification] Input signal
[Function] Selects the mode for writing tool compensation.
[Operation] When this signal is turned “1” in a manual operation mode, the mode for
writing tool compensation is selected. The control unit then automatically
switches the screen displayed on the CRT to the tool geometry
compensation screen and blinks the “OFST” status display in the bottom
of the screen to notify that the mode has been changed to the mode for
writing tool compensation.
