4. Parameters (User)
4.1 Workpiece Coordinate
I -135
(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.
(Example) To calculate X axis (1st axis) in G55 workpiece coordinate system
(Step after (d) Selecting the measurement workpiece coordinate and axis.)
Press the
INPUT SHIFT
keys.
3)
WORK
#(55) DATA ( 9.889)( )( )
The automatically calculated workpiece
coordinate offset data will be displayed at the
cursor position (X axis).
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)
