Starting the automatic run
The homing run is started by the measuring software. Please refer to the
operating instructions for the measuring software.
Park position
After homing, the probe moves to the park position. The park position
coordinates are defined in the measuring software. The coordinates
must be inside the measuring volume.
Example
of a park position: X = 30, Y = -30, Z = -30.
NOTE
The position of the reference sphere has to be redetermined in the fol-
lowing cases after a homing run:
Case 1: Redetermination is necessary if a
stylus system
needs to be re-
qualified. This is required, for example, after supplementing or replacing
a stylus and after a collision.
Case 2: Redetermination is necessary if the position of the
changer rack
or holder has changed.
Stylus system qualification
What you should know!
Why is qualification necessary?
By means of qualification, the stylus vector and diameter are deter-
mined. This data is required to determine the coordinates of the probed
point.
The reference measurement has to be carried out before determining
the stylus vector.
In which cases is qualification necessary?
Qualification is necessary in the following cases:
–
After a collision
–
When the ambient temperature varies considerably and if the stylus
system consists of components having different expansion coeffi-
cients.
–
When inserting a new stylus into the stylus system.
–
When mounting a new probe.
What should be observed during qualification?
Take the following steps during qualification:
