Turn ON Y229 (tool measurement mode).
Preset the following axis specification parameter as the
sensor position. #2015 tlml–, #2016 tlml+
Turn OFF Y229 (tool measurement No.)
Turn ON Y329 (workpiece measurement No.)
Set the compensation No. of the tool to be measured in
the R register.
Tool No.: R2970, Wear data compensation No.: R186
Set the compensation No. of the tool to be used for
cutting in the R register.
The tool length offset amount is automatically calculated
from the contacted position, and is stored in the tool
compensation amount memory.
Tool compensation amount = Machine coordinate value
– Measurement basic value (Sensor position)
The wear amount is cleared after measurement.
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
Interface and operation with NC
◆
Do not move the tool in the Z axis direction after cutting.
◆
The axis movement will stop, and can be moved only in
the direction away from the sensor.
External workpiece offset
◆
The tool compensation amount is measured one axis at a time.
