(1) Mount touch sensor in spindle.
(2) Move the touch sensor with exactly the same feedrate as applied for measuring to the measure point
and memorize the touch point coordinates.
(3) Turn the spindle by 180_ , repeat the procedure as described in (2) and memorize the touch point coor-
dinates.
(4) Calculate the shift amount with the coordinates obtained in (2) and (3) as follows.
A
B
SHIFT = (B coordinate – A coordinate) / 2
180° rotated
(5) Add plus/ minus sign for positive or negative measuring position.
A
As shown on the drawing on the left, the shift amount
becomes negative.
Note) Dont’t spin the spindle during measauring.

2.13.3.3 Over Run calculation
Apply the following described method to calculate the touch sensor over run.
(1) Mount touch sensor in spindle.
(2) Measure the diameter of an accurate ring gage with exactly the same feedrate as applied for centering.
With the result, the over run can be calculated as follows.
D : diameter ring gage.
D’ :measuring result.
d : touch sensor diamter.
OVER RUN = {(D’+d) – D} / 2
Do nots pin thetouchsensor.
