(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.

Set the compensation No. of the tool to be measured in
the R register.
Tool No.: R4720, Wear data compensation No.: R2431
♦ The axis movement will stop, and can be moved only
in the direction away from the sensor.
Set the compensation No. of the tool to be used for
cutting in the R register.
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
