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.

Interface and operation with NC
Turn ON Y721 (tool measurement mode).
Preset the following axis specification parameter as the
sensor position.
Set the compensation No. of the tool to be measured in
the R register.
Tool No.: R4720, Wear data compensation No.: R931
♦ The axis movement will stop, and can be moved only
in the direction away from the sensor.
The tool length compensation amount is automatically
calculated from the contacted position, and is stored in the
tool compensation amount memory.
Tool compensation amount = Machine coordinate value
– Measurement base position (Sensor position)
The wear amount is cleared after measurement.
♦ The tool compensation amount is measured one axis at a time.
Set the compensation No. of the tool to be used for
cutting in the R register.
♦ Do not move the tool in the Z axis direction after cutting.
Turn ON Y7B1 (workpiece measurement No.)
The Z axis workpiece coordinate offset will be measured
and set in the external workpiece offset.
Workpiece coordinate offset = Machine coordinate value
– Tool compensation data
Turn OFF Y721 (tool measurement No.)
