3.2.3 Manual Tool Length Measurement II
(1) Outline
By using a device having a touch sensor, the tool compensation amount can be calculated just by
contacting the tool nose against the touch sensor with manual feed. The calculated results are
stored in the tool compensation amount memory.
After setting the tool compensation amount for each tool, the Z axis external workpiece
coordinate offset data can be set by cutting the edges of the workpiece with manual operation
and inputting the workpiece measurement signal.

1) Measurement
method
1. Set the machine coordinate values of the touch sensor's contact surface in the
parameters beforehand as the measurement basic value.
2. Select the tool for which the tool compensation amount is to be measured.
3. Using manual feed, contact the nose of the tool against the touch sensor.
The tool compensation amount will be calculated from the machine coordinate value
when the touch sensor is contacted and the measurement basic value, and will be saved
in the memory as the tool compensation amount.
Tool compensation amount =
Machine coordinate value – measurement basic value (sensor position)
After measuring, the tool wear amounts for the individually designated tool numbers are
cleared.
2) Number of set axes
The X (1st axis), Z (2nd axis) and additional axis can be set.
The additional axis is determined with the parameter "#1520 Tchg34" (additional axis tool
compensation operation selection).
#1520 Tchg34
Additional axis
0
3rd axis is selected.
1
4th axis is selected.
