(3) Width center workpiece offset measurement
The two points among the measurement position coordinate of the X axis, Y axis or Z axis are
measured, and each axis' groove center is calculated. The calculated result is set in the specified
workpiece coordinate offset.
The workpiece position measurement coordinates are calculated from the skip machine position of
the X, Y and Z axes.
Measurement position coordinate X = X axis' skip machine position + center compensation amount
(horizontal) ± skip flow amount (horizontal)
Measurement position coordinate Y = Y axis' skip machine position + center compensation amount
(vertical) ± skip flow amount (vertical)
Measurement position coordinate Z = Z axis' skip machine position - Sensor length
The +/- of the skip flow amount changes according to the tool movement amount during
measurement

The offset (rotation center and rotation angle) of the rotary coordinate system is measured, and the results
are set to the workpiece coordinate system offset (rotation center) and the parameters.
<Measurement using touch sensor>
Measurement counter X = X axis skip position (Machine position)
Measurement counter Y = Y axis skip position (Machine position)
<Simple measurement (measurement without using touch sensor)>
Measurement counter X = X axis machine position + center compensation (H) + skip past amount
(Horizontal axis) (Note)
Measurement counter Y = Y axis machine position + center compensation (V) + skip past amount (Vertical
axis) (Note)
(Note)
The skip past amount is added for only the axis that moved last.
The sign ( + or - ) of the skip past amount depends on the movement direction of the axis.

To set the workpiece coordinate offset, the position
X (position Y, position Z) of the measurement A
point is measured, and the measured value is set in
the measurement A point. In the same manner as
the measurement A point, the measurement B point
is measured and set.
The groove width center coordinate of the X axis (Y
axis, Z axis) is calculated by setting the workpiece
coordinate system after setting two points, and the
calculated result is set in the workpiece coordinate
offset
