Siemens SINUMERIK 840D sl Programming Manual page 207

Starting position before the measurement
The probe must be positioned above the set sphere center point of the 1st sphere at a safe
height.
Note
The measuring points must be selected so that there is no danger of a collision with a sphere
fixture or another obstacle during measuring or intermediate positioning.
The measurement path in parameter DFA should be selected so large that all measuring points
can be reached within total measurement path 2 x DFA. Otherwise no measurement can be
performed or the measurements are incomplete.
Position after the end of the measuring cycle
The probe is above the determined sphere center point of the 3rd sphere at a safe height
(height at the starting position).
Procedure
The part program or ShopMill program to be processed has been created and you are in the
editor.
