5 Setting a Tool and a Workpiece
Details of automatic calculation expression (When the workpiece measurement signal is used)
The external workpiece coordinate offset data is automatically calculated with the following expression.
External workpiece coordinate offset = Machine coordinate value - Tool compensation data
The tool compensation data used for the measurement is selected with the base specification parameter "#1226 aux10
bit0".
#1226 aux10 bit0

Details of automatic calculation expression (When the menu [MeasVal take in] is used)
The workpiece coordinate offset data is automatically calculated with the following expression.
The calculation expression changes according to the parameter "#8709 Ext work sign rvs".
When "#8709" is "0":
Workpiece coordinate offset = Machine coordinate value - External workpiece coordinate offset - Tool compensa-
tion data
When "#8709" is "1":
Workpiece coordinate offset = Machine coordinate value + External workpiece coordinate offset - Tool compensa-
tion data
Select the tool compensation data used for the measurement with the parameter "#1226 aux10 bit0".
#1226 aux10 bit0
