4.1 Workpiece Coordinate
I-137
(d) Selecting the measurement workpiece coordinate and axis
Set the workpiece coordinates to be measured in the # ( ) setting area, and then move the cursor
to the setting area of the axis to be measured.
(Example) To measure the X axis (1st axis) of the G55 workpiece coordinate system.
Set 55 in # ( ).

(e) Automatically calculating the workpiece coordinate system offset data
When the
INPUT
SHIFT
keys are pressed, the selected axis' workpiece coordinate offset data will be
automatically calculated from the machine value, tool length data and tool nose wear data. The
calculation results will be displayed in the setting area.
The setting mode (absolute value setting/increment value setting) will automatically be set to the
absolute value setting.

(Step after (d) Selecting the measurement workpiece coordinate and axis.)
Press the

1) Details of automatic calculation expression
The workpiece coordinate offset data is calculated with the following expression.
Workpiece coordinate offset data = machine value – (tool length data + tool nose wear data)
