Movements
:
1. The probe moves to the center position of the 1
st
measuring hole with feed-rate (fa).
2. Moving the distance (Z) along –Z axis with feed-rate (fa).
3. Moving the distance (D/2 -
α
- stylus radius) along +X axis with feed-rate (fa).
4. Moving within the distance (D/2 +
γ
- stylus radius) with the feed-rate (f) until touching
the work-piece.
5. Return the center position of the hole with rapid traverse.
6. Repeat steps 1. to 5. in the direction –X axis and
±
Y axis.

First measurement
7. Moving to the position (1
st
measuring position -
β
) along +X axis with feed-rate (fa).
8. Moving within the distance (
β
+
γ
) with the feed-rate (f) until touching the work-piece.
9. Repeat steps 7. to 8. in the direction –X axis and
±
Y axis.

Second measurement
10. Repeat steps 1. to 9. in the 2
nd
hole.
When
G192
is executed, the system will calculate the angle of X axis from measurement
position and output it to the following variables.
#250
: Angle between X-axis and line through 2-holes center
