Precautions for manual tool measurement l
(1) When compensation amount is written for an axis that has not completed zero point return, the operation message "TLM
axis not returned to ref. position" will appear.
(2) When the parameter "#8924 MEAS. CONFIRM MSG" is set to "1", the menu "Offset write" is highlighted and confirma-
tion message "OK? (Y/N)" is displayed. When you press the [Y] (or [INPUT]) key, the measurement position is written
as the tool compensation amount. When you press any other key, the offset is not written. At this time, menu highlighting
is canceled and the operation message is erased.
(3) When the parameter "#1124 ofsfix" is set to "0", the cursor moves to the next offset No. However, when "#1124 ofsfix"
is "1", the cursor does not move to the next offset No.
(4) When the parameter "#11017 T-ofs set at run" (Tool compensation amount setting during automatic operation enabled)
is set to "1", the tool compensation amount data can be set even during automatic operation or operation pause.
Carrying out tool measurement (Manual tool length measurement II)
(1) Select the tool to be measured with manual numeri-
cal value command. (Refer to "8.4 Manual Numerical
Value Command" for details.)
(2) Set the compensation No. of the compensation data
to be set in "Tool No. (Tool length measurement 2)"
(PLC device).
(3) Set the compensation No. of the wear data to be
cleared in "wear compensation No. (tool presetter)"
(PLC device).
(4) Turn ON the measurement switch.
(5) Move the additional axis in the minus direction by
manual feed and have the tool nose contact with the
touch probe.
(6) Turn the measurement switch OFF.
Note
(1) When entering the sensor area, the axis can be moved only in one direction selected from +X, -X, +Z, -Z, (+Y, -Y). If
two axes are moved simultaneously, measurement will not be carried out. However the axis movement stops for safety
with displaying "TLM axis is illegal".
(2) If the tool nose is contacting the sensor, the axis can be moved only in the direction moving away from the sensor.
Whether or not the tool nose is detached from the sensor can be judged by the following conditions.
The sensor signal has been turned OFF for 500 ms or more.
The tool nose is moved 100 μm or more after the sensor signal has turned OFF.
The above conditions are set with parameter "#1227 aux11/bit2" (measures against tool setter chattering).
"On mea" is displayed.
Guide drawing for manual tool length measurement II is
displayed.
Tool compensation data is displayed, placing the com-
pensation No. set in "Tool No. (Tool length measure-
ment 2)" (PLC device) at the top.
<Note>
The row at the cursor position will not be changed.
Measurement value is set for the additional axis of the
compensation No. set in "Tool No. (Tool length mea-
surement2)" (PLC device).
"On mea" disappears.
